Mothers in Science
The aim of this book is to illustrate, graphically, that it is perfectly possible to combine a successful and fulfilling career in research science with motherhood, and that there are no rules about how to do this. On each page you will find a timeline showing on one side, the career path of a research group leader in academic science, and on the other side, important events in her family life. Each contributor has also provided a brief text about their research and about how they have combined their career and family commitments. This project was funded by a Rosalind Franklin Award from the Royal Society 1 Foreword It is well known that women are under-represented in careers in These rules are part of a much wider mythology among scientists of science. In academia, considerable attention has been focused on the both genders at the PhD and post-doctoral stages in their careers. paucity of women at lecturer level, and the even more lamentable The myths bubble up from the combination of two aspects of the state of affairs at more senior levels. The academic career path has academic science environment. First, a quick look at the numbers a long apprenticeship. Typically there is an undergraduate degree, immediately shows that there are far fewer lectureship positions followed by a PhD, then some post-doctoral research contracts and than qualified candidates to fill them. Second, the mentors of early research fellowships, and then finally a more stable lectureship or career researchers are academic scientists who have successfully permanent research leader position, with promotion on up the made the transition to lectureships and beyond. -
Making Quantum Technology Ready for Industry
Brussels 28/29 March 2019 Making Quantum Technology ready for Industry Putting Science Into Standards (PSIS) Workshop on Quantum Technology CEN-CENELEC Management Centre Rue de la Science 23, 1040-Brussels www.cencenelec.eu www.ec.europa.eu/jrc/en #Standards4Quantum Workshop structure On 28th and 29th of March 2019, the Joint Research Centre and CEN/CENELEC hold at the CEN/ CENELEC Management Centre (CCMC) in rue de la Science 23, Brussels, a workshop titled Making Quantum Technology Ready for Industry. The workshop focuses on current standards and potential standardisation fields in quantum technologies and is organised with the support of the German Institute for Standardization (DIN) and DG CNECT, the host of the EU Quantum Flagship. In Europe, the European Telecommunications Standards Institute (ETSI) has established an Industry Specification Group with a specific focus on quantum key distribution (QKD). At the international level, standardization is taking place within Joint Technical Committee 1 of ISO/IEC addressing among others cybersecurity and data protection. CEN and CENELEC have signed agreements with ISO and IEC through which common European and international standards can be developed in parallel, thereby avoiding duplication of work Since many quantum technology areas are advancing on the technology readiness level scale, it is important to prepare the field for standardization activities, helping to facilitate and accelerate market uptake of quantum technology. The workshop provides: 1. an overview of how standardization can be useful to the quantum innovation process; 2. what standardizers can do for the quantum science community. To contribute to the different pace in the main quantum areas, the workshop is divided in four technical sessions. -

DCPT-18/27 Negative modes of Coleman-de Luccia and black hole bubbles Ruth Gregory,1, 2, ∗ Katie M. Marshall,3, † Florent Michel,1, ‡ and Ian G. Moss3, § 1Centre for Particle Theory, Durham University, South Road, Durham, DH1 3LE, UK 2Perimeter Institute, 31 Caroline Street North, Waterloo, ON, N2L 2Y5, Canada 3School of Mathematics, Statistics and Physics, Newcastle University, Newcastle Upon Tyne, NE1 7RU, UK (Dated: April 26, 2019) We study the negative modes of gravitational instantons representing vacuum decay in asymptotically flat space-time. We consider two different vacuum decay scenarios: the Coleman-de Luccia O(4)-symmetric bubble, and O(3) × R instantons with a static black hole. In spite of the similarities between the models, we find qualitatively different behaviours. In the O(4)-symmetric case, the number of negative modes is known to be either one or infinite, depending on the sign of the kinetic term in the quadratic action. In contrast, solving the mode equation numerically for the static black hole instanton, we find only one negative mode with the kinetic term always positive outside the event horizon. The absence of additional negative modes supports the interpretation of these solutions as giving the tunnelling rate for false vacuum decay seeded by microscopic black holes. I. INTRODUCTION arXiv:1808.02305v2 [hep-th] 25 Apr 2019 False vacuum decay through the nucleation of true vacuum bubbles has many important applications ranging from early universe phase transitions to stability of the Higgs vacuum. The process has an elegant description in terms of Euclidean solutions to the underlying field equations that extend the bubbles into imaginary time [1, 2]. -

Zu den Highlights zählten zweifelsohne die Jahrestagung der World Academy of Sciences mit Teilnehmerinnen und Teilnehmern aus über 60 Ländern sowie – für mich persönlich – mein Besuch beim CeMM gemeinsam mit dem Staatspräsidenten der Italienischen Republik, Sergio Matarella. Darüber hinaus stellt der Start der Initiative „Genom Austria“, über die meine Frau den Ehrenschutz übernommen hat, ein wegweisendes Projekt dar, in dem ganz konkret die gesellschaftliche Bedeutung der modernen Genetik und ihrer Möglichkeiten untersucht werden soll. Exemplarisch wird damit die Foto: Ingo Pertramer Notwendigkeit aufgezeigt, die naturwissenschaftlich-technische Entwicklung mit der Öffentlichkeit zu diskutieren, Transparenz und Mündigkeit zu stärken und so eine auf Wissen gründende Partizipation an heutiger Spitzenforschung zu ermöglichen. Ich erwähne dieses Beispiel von „Genom Austria“ auch deshalb, weil an ihm deutlich wird, in welchem hohen Maße sich die Österreichische Akademie der Wissenschaften als Ort der Wissenschaft und als Ort des gesellschaftlichen Diskurses versteht. Dafür möchte ich allen Beteiligten danken. -

We find that the metric is approximately a scaled version of the empty space string metric, i.e. conical in nature. We use our results to place bounds on the amount of cylindrical gravitational radiation currently emitted by such a string. We then analyse explicitly the gravitational radiation equations and show that even initially large disturbances are rapidly damped as the expansion proceeds. The implications for the gravitational radiation background and the limitations of the quadrupole formula are discussed. 0 Oporrtod by Universities Research A8SOChtiOn Inc. under contract with the United States Department of Energy 1 Introduction. -_- -- Cosmic strings' have attracted a lot of attention recently as they give a compelling and plausible description of structure in the universe. They are topological defects which can be formed when the universe undergoes a suitable phase transition to a spontaneously broken symmetry state. The condition for string formation is that the vacuum manifold (the set of vacuum states of the theory) is not simply connected2. The strings responsible for galaxy formation are GUT strings, i.e. those formed during phase transitions at the GUT scale, 10I5GeV. -

These com- pact objects are extraordinarily efficient at producing electromagnetic and gravitational radiation. As such, they are ideal laboratories for fundamental physics and they have an immense discovery potential. The detection of merging black holes by third-generation Earth-based detectors and space-based detectors will provide exquisite tests of general relativity. Loud “golden” events and extreme mass-ratio inspirals can strengthen the observational evidence for horizons by mapping the exterior spacetime geometry, inform us on possible near-horizon modifications, and perhaps reveal a breakdown of Einstein’s gravity. Measure- ments of the black-hole spin distribution and continuous gravitational-wave searches can turn black holes into efficient detectors of ultralight bosons across ten or more orders of magnitude in mass.
