Kavli IPMU Annual Report 2013 1 Foreword

It is a good time to reflect on the first seven years of our institute. The Kavli Institute for the Phys- ics and Mathematics of the Universe (Kavli IPMU) was founded seven years ago on October 1, 2007. We proposed to address five basic questions about the Universe, how it began, what it is made of, what its fate is, what its fundamental laws are, and why we exist in it. We do so by combining mathematics, physics, and astronomy, employing accelerator-based experiments, underground experiments, and observations at telescopes. This Institute literally started from scratch, but now has grown to a size of about 150 people on site including graduate students and support staff.

Overall, I believe the Institute came out to be exactly as proposed. Our unique building allows mathematicians, physicists and astronomers to be under the same roof, sharing seminars and the daily teatime. Interdisciplinary discussions have become a commonplace. The Institute is highly international; more than a half of the members are not Japanese nationals. Every member was hired anew, and the quality of the hires is clear; about 90% of the postdocs have been offered positions at other excellent institutions after their term at Kavli IPMU, and more than a third of them are on faculty positions by now. Our citation counts are similar to other world-leading research institutions. Thanks to several high profile papers and high international visibility, our members are invited to major conferences as keynote or summary speakers. We advertise positions interna- tionally and attract nearly a thousand applications each year.

Many papers were written based on mutual inspiration of mathematicians and physicists. Key “in- terpreters” to overcome the language barrier between mathematicians and physicists played critical roles to make it possible. This is crucial to address the question “what are the fundamental laws?” The large projects proposed in the original proposal are producing fruits. The direct dark matter detection experiment XMASS was built and produced world best limits on some candidates. It is addressing the question “what is the Universe made of.” The KamLAND-Zen effort produced the world best limit on neutrinoless double beta decay (this result was published in February, 2013, namely, in FY2012). Hyper Suprime-Cam (HSC) was designed, built, commissioned, and the 300-night survey was approved on the Subaru telescope, one of the largest in the world. Data from the initial few nights are being analyzed. Combined with the theoretical research by our members, they address the question “why do we exist.” Hitoshi Murayama Director We proposed Prime Focus Spectrograph (PFS) in 2009, which is now under construction. The combination of imaging survey using HSC and spectroscopic survey using PFS on the same telescope promises to be a world-leading observational program, looking into “the fate of the Uni- verse” a trillion years from now. We are now proposing LiteBIRD satellite experiment to look for the evidence for the cosmic inflation, to address the question “how did the Universe begin?” looking back to the era when the Universe we see today was much smaller than the size of an atomic nucleus, only 10–37 seconds from the Beginning.

All of this progress will be lost if the institute cannot secure funding. Fortunately thanks to the strong leadership of President Junichi Hamada, the University promised to sustain our institute at some level. In addition, the Kavli Foundation donated endowment to give us flexibility. We now know we will not disappear from the map. We are looking into an even brighter future!

The Kavli IPMU has a rather unique organization. While research is conducted in a flat- structure manner with loosely defined grouping, the decision making is done in a top-down scheme under the Director’s strong leadership. This scheme minimizes the administrative load for the researchers. It is also intended to maximally extract young researcher’s cre- ative and challenging minds as well as to encourage daily cross-disciplinary interactions.

The Director is appointed by the President of the University of Tokyo and reports directly Kavli IPMU to his office. The Director proposes to hire the Principal Investigators to the President. For other hiring of research staff and administrative staff, he has a complete authority. He is Organization Kavli IPMU Management also solely responsible for making all other decisions. He is assisted by the two Deputy Directors, the Associate Director, and the Administrative Director. They constitute the President TODIAS Director Executive Board (EB) and regularly meet to ensure smooth operation of the Institute. The Junichi Hamada Director: Yoichiro Matsumoto Hitoshi Murayama EB has direct access to the Office of the President for consultations on both scientific and administrative matters.

Function fields and Langlands correspondence Even though the main goal of arithmetic is to understand number fields, it is observed that function Langlands correspondence fields of one variable over finite fields behave quite similarly. Function fields have an advantage that for function fields and -adic we can use “geometric methods,” for instance cohomology theories. Not only making us easier to treat 5.1 the field, this perspective enables us to “export” ideas of arithmetic to, say, complex geometry. In fact, cohomology theory “geometric Langlands correspondence,” which is a certain correspondence of sheaves on Riemann surfaces, was formulated under this spirit. It seems geometric Langlands correspondence has some 풑 relation with S-duality, which is a physical theory, but we do not go into further details in this report. Tomoyuki Abe V. Drinfeld proposed a program to establish the Langlands correspondence for function fields and carried it out in certain cases. He was awarded Fields medal by this contribution. The method was Number theory and Galois expanded by L.

It turns out that the theory of primitive forms for a function F is relevant in the complex geometric (B- model) aspects of N=(2,2) supersymmetric LG (Landau-Ginzburg) theory in physics, having F as its superpotential (K. Hori). The theory has therefore become a common subject of physicists and mathematicians in Math-String seminar at IPMU. The dualities between different string models in physics give strong non-perturbative means to calculate the partition functions. For instance, Witten showed that the Landau-Ginzburg model and the sigma-model on a Calabi-Yau manifold give different phases of the same physics. The mirror symmetry (worked out by physicists K. Hori, C. Vafa, cf. Kontsevich, Yau-Zaslov-Strominger) is one of the dualities, which has had a strong impact on mathematics, since it predicts an unexpected duality between complex geometry and symplectic geometry. We explain below new developments in this subject, which took place at IPMU in the last year, and confirmed the LG-LG mirror symmetry using primitive forms.

5.10 Status of the T2K experiment

Mark Hartz

Neutrino oscillations, are a phenomenon where one type or “flavor” of neutrino oscillates to another

as the neutrino travels through matter or vacuum. The discovery of neutrino oscillations confirmed the cp 3 existence of small but non-zero neutrino masses, evidence of physics beyond the Standard Model of δ particle physics. Now the Tokai-to-Kamioka (T2K) experiment has begun the search for Charge-Parity 2 (CP) violation in the oscillations of neutrinos. In a CP violating process, the laws governing matter and antimatter are different. If CP violation by neutrinos is found, it may explain why the universe is made of matter only, and not equal parts of matter and antimatter, through the process of leptogenesis. 1

T2K detected the first indication of e oscillations in 2011 with the observation of 6 e candidate events at the SK detector (Phys. Rev. Lett. 107 (2011) 041801).

Since neutrinosν →νand antineutrinos are produced and interact at different rates, a significant challenge for T2K will be the combined analysis of neutrino and antineutrino data with the proper accounting of all systematic effects.

Mark Vagins Research Highlights

Following 18 months of construction, EGADS first became operational in 2011, initially running with pure water. Various adjustments and tuning of the equipment followed, and by 2013, once it had been demonstrated that the filtered pure water in EGADS was equal in quality to that in Super-K, 400 ki- lograms of gadolinium sulfate—a world’s record—was dissolved in the 200 ton main tank, allowing large-scale studies of gadolinium filtration and transparency to begin. The EGADS selective filtration system has achieved a gadolinium retention rate of 99.97% per pass, while simultaneously cleaning unwanted impurities from the water: unprecedented, and a major technical achievement.

Now, with full gadolinium loading we are within 15% of the transparency of ultrapure water. This is probably already sufficient, but work continues to improve upon this result. Further comparative studies both with and without dissolved gadolinium in the 200 ton tank will take place during 2014.

The average mass map (Figure 2) is remarkably symmetrical eighty years ago. Nevertheless, astronomers cannot directly see dark matter in the night sky, and with a pronounced mass peak. The mass density distribution for individual clusters shows a wide range particle physicists have not yet identified a dark matter particle in their experiments. “What is dark of densities.

We wanted to use a large sample of galaxy clusters to find out how the density of dark matter changes from the center of a typical galaxy cluster to its outskirts. Sample of 50 galaxy clusters Average Dark Matter Map The density of dark matter depends on the properties of the individual dark matter particles, just like the density of everyday materials depends on their components. CDM, the leading theory about dark matter to date, describes that dark matter particles only interact with each other and with other matter high density via the force of gravity; they do not emit or absorb electromagnetic radiation and are difficult if not impossible to see. Therefore, we chose to observe dark matter by using gravitational lensing, which detects its presence through its gravitational interactions with ordinary matter and radiation. Accord- ing to Einstein’s theory of relativity, light from a very distant bright source bends around a massive CDM object, e.g., a cluster of galaxies, between the source object and the observer. It follows from this principle that the dark matter in cosmic giants like galaxy clusters alters the apparent shape and position of distant galaxies. The Subaru Telescope allows us to measure very precisely how the dark matter in galaxy clusters distorts light from distant galaxies and gauge tiny changes in the appearance of a huge number of faint galaxies (Figure 1). low density

These so called “spectral signatures” provide a measure of the distance to the galaxy (i.e., its redshift). The ratio of the intensity of H relative to H providesα a measureβ of obscuring dust. The strength of the emission lines indicates the rate at which stars are forming while the ratio of [NII] relative to H is indicative of the level of βchemical enrichmentα of the interstellar medium (i.e., metallicity). The FMOS-COSMOS survey is the largest near-infrared spectroscopic survey of galaxies at high spectral resolutionα and high redshift yet to be undertaken. Scientific results include the following:

1) Galaxy growth and a star-forming ‘main sequence.’ There is a highly ordered, general decline in the rate at which galaxies form stars over cosmic time. The FMOS observations shown in Figure 2 confirm that the rate of star formation varies with the total mass in stars. Although this relationship was first seen locally, this research shows that star formation not only persisted in early epochs but also that its rates of star formation were 20 times higher then! The star formation rate increases with a look-back time out to a corresponding redshift of z 1.6. While this has been observed using other indicators (ultraviolet or infrared) at high redshift, FMOS’s detection of the H emission line in the near infrared provides a consistent way to measure star∼ formation in the early Universe and compare it Figure 1: ‌FMOS spectra in the J-band (left panel) and H-band (right panel), each of which filters light so that only α specific wavelengths can pass through.

Hydrogen, the most common element in the universe, was missing, and no helium was detected. There was, however, strong evidence for silicon and sulfur, which allowed Quimby to uniquely clas- sify PS1-10afx as a Type Ia supernova. Given the redshift, which was set first by matching the broad spectral features to templates and second by narrow lines from the host galaxy, the broad band colors The small size of this lens galaxy and the large magnification it produced were not exactly what the of PS1-10afx were consistent with those expected from a Type Ia supernova as well, and these colors experts would have predicted for the first discovery of a gravitationally lensed Type Ia supernova, evolved over time just as expected. To Quimby’s team, this left just one explanation: PS1-10afx was a but they may very well be typical of discoveries to come. Because the likelihood of lensing increases normal Type Ia supernova, but it was simply 30 times brighter than it should be. There was only one quickly with redshift, and the Type Ia production rate also increase with redshift, it turns out to be straightforward way to explain this. more probable to find a highly magnified, high-redshift Type Ia supernova than a less magnified, lower-redshift one. A consequence of this is that most of the gravitationally lensed Type Ia supernovae The physics of Type Ia supernovae has been studied in detail over the past three decades, and there that will be found with searches such as the coming Large Synoptic Survey Telescope can be identi- is no known way to produce a Type Ia supernova with normal colors and a normal light curve but a fied by their colors, the higher redshift, gravitationally lensed supernovae being redder than the more substantially higher luminosity.

This means that the survey need not resolve the individual image compo- than Type Ia usually have higher temperatures (bluer colors) and larger physical sizes (and thus slower nents, which enables more low-mass galaxies to serve as foreground lens and, over-all, increases the light curves). New physics would thus be required to explain PS1-10afx as an intrinsically luminous expected number of gravitationally lensed Type Ia supernovae by an order of magnitude. supernova. However, Quimby’s team found a second explanation that required only well demonstrated physics: gravitational lensing.

This adds an additional phase delay. By Although the available observations were consistent with the hypothesis of Quimby’s team, there was timing the delays precisely and comparing these to the delay expected from the geometry of the lens, one glaring omission that led some to question their solution: where was the lens galaxy?

Last September, Quimby’s team set out to find the hidden lens. Using the Low-Resolution Imaging Spectrograph on the 10 meter Keck-I telescope, they spent 7 hours collecting light at the location of PS1-10afx, which had by then faded away itself (see figure 1). After carefully extracting the signal from the data, Quimby’s team had their confirmation. Buried in the glare of the relatively bright host galaxy was a second, foreground galaxy (see figure 2). This second galaxy was faint enough to have previously gone unnoticed, but the analysis of Quimby’s team showed that it was still the right size to explain the gravitational lensing of PS1-10afx.
