2+1D Quantum Field Theories in Large N Limit 2 + 1d Quantum Field Theories in Large N limit by Hamid Omid M.Sc Theoretical Physics, The University of British Columbia, 2011 B.Sc Theoretical Physics, Isfahan University of Technology, 2009 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF Doctor of Philosophy in FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Physics) The University Of British Columbia (Vancouver) January 2017 c Hamid Omid, 2017 Abstract In Chapter 1, we present a brief introduction to the tight-binding model of graphene and show that in the low-energy continuum limit, it can be modeled by reduced QED2+1. We then review renormalization group technique which is used in the next chapters. In Chapter 2, we consider a quantum field theory in 3 + 1d with the defect of a large number of fermion flavors, N. We study the next-to-leading order contri- butions to the fermions current-current correlation function h jm (x) jn (y)i by per- forming a large N expansion. We find that the next-to-leading order contributions 1=N to the current-current correlation function is significantly suppressed. The suppression is a consequence of a surprising cancellation between the two con- tributing Feynman diagrams. We calculate the model’s conductivity via the Kubo formula and compare our results with the observed conductivity for graphene. In Chapter 3, we study graphene’s beta function in large N. We use the large N expansion to explore the renormalization of the Fermi velocity in the screening dominated regime of charge neutral graphene with a Coulomb interaction. We show that inclusion of the fluctuations of the magnetic field lead to a cancellation of the beta function to the leading order in 1=N. The first non-zero contribution to the beta function turns out to be of order 1=N2. In Chapter 4, we study the phase structure of a f 6 theory in large N. The ii leading order of the large N limit of the O(N) symmetric phi-six theory in three dimensions has a phase which exhibits spontaneous breaking of scale symmetry accompanied by a massless dilaton. In this chapter, we show that this “light dila- ton” is actually a tachyon. This indicates an instability of the phase of the theory with spontaneously broken approximate scale invariance. We rule out the exis- tence of Bardeen-Moshe-Bander phase. In this thesis, we show that Large N expansion is a powerful tool which in regimes that the system is interacting strongly could be used as an alternative to coupling expansion scheme. iii Preface This thesis is based on notes written by myself during my PhD program and also publications authored by my collaborators and me. Most of the calculations were done by myself. The ideas were developed during several meetings between my supervisor and myself. Chapter 2 is the study of AC conductivity of 2 + 1d Dirac semi-metal in the large N Limit. A version of this chapter is prepared to be pub- lished. Chapter 3 is the study of the beta function of charge neutral 2 + 1d Dirac Semi-metal in the large N. A version of this chapter is also prepared to be pub- lished. In Chapter 4, we investigate f 6 theory in the large N limit. A version of this chapter is accepted to be published in Phys. Rev.

The series is even due to particle-hole and time reversal symmetry. The Feynman integrals for diagrams with more than two legs are finite. 54 Figure 3.2 The leading contribution to the beta function in the large N limit comes from the Feynman diagram where the dotted line is the relativistic large N propagator and the insertion into the photon propagator is the tree-level classical Coulomb action which is non-relativistic. This diagram is of order 1=N2. 57 Figure 3.3 We have plotted the beta function in [55] (purple) vs. Eq.(3.19) (orange). As one expects in the limit of v ! 1 (here we have chosen the units such that light velocity is our measure for velocity), we find that the Lorentz symmetry prevents the Fermi velocity from running. The beta function in [55] violates this condition as its Lorentz symmetry is violated by con- struction but not the presence of the two velocities in the Lagrangian. 65 Figure 3.4 We have plotted the beta function in [55](dashed lines) vs. Eq.(3.19) (solid lines). The orange, purple and green lines respectively correspond to N = 4;10;100 . ............................. 66 Figure 3.5 By zooming into p q regime, we only check that a given theory with an infrared limit that corresponds to the ultraviolet regime of Eq.(3.21) will be infrared divergent free. ..................... 69 x Figure 3.6 Adapted from [18].

These proceedings contain lectures on field theory and the Standard Model, quantum chromodynamics, CP violation and flavour physics, as well as reports on cosmic rays, the Pierre Auger Project, instrumentation, and trigger and data-acquisition systems. iii Preface The third in the new series of Latin American Schools of High-Energy Physics took place in Malargüe, lo- cated in the south-east of the Province of Mendoza in Argentina, from 27 February to 12 March 2005. It was organized jointly by CERN and CLAF (Centro Latino Americano de Física), and with the strong support of CONICET (Consejo Nacional de Investigaciones Científicas y Técnicas). Fifty-four students coming from eleven different countries attended the School. While most of the students stayed in Hotel Rio Grande, a few students and the Staff stayed at Microtel situated close by. However, all the participants ate their meals to- gether at Hotel Rio Grande. According to the tradition of the School the students shared twin rooms mixing nationalities and in particular Europeans together with Latin Americans. María Teresa Dova from La Plata University was the local director for the School.

Allison Physics at the University of Chicago has a remarkable history. From Albert Michelson, appointed by our first president William Rainey Harper as the founding head of the physics department and subsequently the first American to win a Nobel Prize in the sciences, through the mid-20th century work led by Enrico Fermi, and onto the extraordinary work being done in the department today, the department has been a constant source of imagination, discovery, and scientific transformation. In both its research and its education at all levels, the Department of Physics instantiates the highest aspirations and values of the University of Chicago. Robert J.

We are proud to present the first issue of Chicago Physics – an annual newsletter that we hope will keep you connected with the Department of Physics at the University of Chicago. This newsletter will introduce to you some of our students, postdocs and staff as well as new members of our faculty. We will share with you good news about successes and recognition and also convey the sad news about the passing of members of our community.

  • Quantum Emergence: Entangling the Universe 1 Leo P. Kadanoff
    Quantum Emergence: Entangling the Universe Leo P. Kadanoff ([email protected]) University of Chicago Perimeter Institute Pitt Emergence October 2015 1 Monday, August 24, 2015 abstract This talk is about emergence as seen by a theoretical physicist. Simply stated, I see an emergent result as any scientific conclusion that is a subtle or unexpected result of the basic postulates of a scientific field. The talk starts by describing some of the ways this can happen. It continues with a detailed discussion of entanglement in quantum mechanics. Quantum entanglement is an idea that was added to the basic quantum theory ten years after that theory was put together in 1924-5. Its impact began to be felt only twenty-five years later with the work of John Bell. Since then the entanglement concept has formed the basis for entire fields of science. For example, it has had a dominating influence on “hard” condensed matter physics. Pitt Emergence October 2015 2 Monday, August 24, 2015 Possible Views of Emergence: I. An Emergent result is anything that surprises the investigator. In 1665, the scientist and clockmaker Christiaan Huygens noticed that two pendulum clocks hanging on a wall tended to synchronize the motion of their pendulums. A similar scenario occurs with two metronomes placed on a piano: they interact through vibrations in the wood and will eventually coordinate their motion. abstract This result is somewhat surprising since the coupling between two clocks or two metronomes is likely to be very weak. abstract Huygens then looked further into his accidental discovery by setting up an experiment to demonstrate the synchronization phenomenon.lab manager The material on Huygens is taken from an unpublished work by Mogens Jensen and LPK.
