VI Cosmology and the Quantum Vacuum, Barcelona, Spain

The focus of this workshop will be on different aspects of modern theoretical cosmology, the challenges of the theory being consistent with experimental data, and the unavoidable connection of cosmological models with the quantum nature of the vacuum. A basic question in modern cosmology is: why we do not see vacuum fluctuations at cosmological scale? In addition, should the singularities of cosmological theories be treated as necessary ingredients of the classical theory or should them be considered as indicators of an underlying quantum theory, yet to be discovered? We aim to bring along to this workshop all the leading scientists working on those problems and discuss state of the art results on the above, strongly interdependent, areas of fundamental physics. The workshop will hence cover topics related to modified theories of gravity, theories of dark energy and inflation, the description of the universe’s evolution according to these theories and the incipient but compulsory modification of those within the theoretical frameworks of quantum gravity, including loop quantum cosmology, an elegant theory providing up to date a singularity free cosmological evolution.

Describing and understanding the quantum vacuum is always a challenge to all these theories, as is also the comprehension of the main manifestation available of the quantum vacuum at nanometric scales, namely the Casimir effect (e.g., when confronted with van der Waals forces).

Conference on the Foundations of Cosmology and Quantum Gravity, NYU, Abu Dhabi, UAE

Call for Papers: Conference on the Foundations of Cosmology and Quantum Gravity (FCQG 2020) At New York University Abu Dhabi (NYUAD) on January 19-21, 2020.

The conference is being jointly sponsored by the NYUAD Institute and two generous grants from the Templeton Foundation – one supporting the ‘Beyond Spacetime’ project based at Illinois-Chicago and Geneva, and the other supporting the ‘New Directions in Philosophy of Cosmology’ based at UC-Irvine and Western University.

KEYNOTE SPEAKERS INCLUDE

Robert Brandenberger (Physics, McGill University)
Karen Crowther (Philosophy, University of Oslo)
Richard Dawid (Philosophy, Stockholm University)
Daniele Oriti (Physics, Max Planck Institute for Gravitational Physics)
Mairi Sakellariadou (Physics, Kings College London)
Chris Smeenk (Philosophy, Western University)

The problem of reconciling general relativity with quantum theory remains a persistent problem in theoretical physics. Competing approaches make salient deep conceptual disagreements that engage physicists, mathematicians, and philosophers alike. These disputes are particularly pressing in the cosmological context, both because the interaction between gravitational and quantum effects are likely to be pronounced in the early universe and because cosmology offers an arena in which one might conceivably adjudicate between competing approaches. Moreover, the ‘ingredient theories’ of modern and quantum cosmology: general relativity, statistical mechanics and quantum mechanics – possess their own unique conceptual difficulties and puzzles. In general relativity, for example, there are significant questions about how to understand the nature of spacetime singularities, and in quantum theory there are persistent questions about how to understand measurements, observers, and the phenomenon of decoherence when the framework is extended to the universe as a whole. How do these issues interact and inform each other in the development of quantum gravity, and what new conceptual puzzles does quantum gravity engender?

This conference explores the relationship between modern cosmology and theorizing about quantum gravity – in short, the foundations of quantum cosmology – with the aim of assessing recent proposals and exploring new directions for research.

We anticipate bringing together philosophers and physicists whose work is at the forefront of foundational issues in these fields. We solicit papers on any topic in the philosophical foundations of cosmology and quantum gravity. We are particularly interested in work that addresses foundational issues involved in the interaction of quantum gravity with modern cosmology and astrophysics including blackholes.

Please submit an extended abstract of around 500 words, together with the title of the talk. The abstract should be anonymized for blind refereeing. Advanced PhD students or recent PhDs are particularly invited to submit abstracts, as are women and underrepresented minorities. All sessions will be videoed for public distribution after the meeting. Accommodation and most meals will be covered for all selected speakers. In addition an honorarium of at least $600 if coming from Europe (or comparable distance) and at least $1200 if coming from North America (or comparable distance) will be provided for. (Contributing speakers will be responsible for their own travel costs.)

Deadline: 20th Oct 2019, with decisions being communicated by the second week of November.

Abstracts should be submitted to: https://easychair.org/conferences/?conf=fcqg2020

CoSyne: Cosmological Synergies in the upcoming decade, Paris, France

The coming decade of astrophysics and cosmology will be driven by a large number of missions which will explore the cosmos observing the sky through e.g. electromagnetic waves, cosmic and gamma rays, gravitational waves and neutrinos. This will make possible a multi-messenger approach, capitalizing on multiple probes that capture phenomena of the Universe in different observational channels over a large range of redshifts and will open the opportunity to study the synergies between different experiments.

The conference will bring researchers working on theoretical aspects, statistical methods and observational cosmology and will discuss the new directions of fundamental physics and cosmological mysteries which can be addressed from these multi-messenger multi-frequency probes. Along with probing the fundamental aspect of gravity, nature of dark energy, properties of dark matter, primordial gravitational waves, neutrino masses and hierarchy, next-generation missions will also be powerful probes to learn about the astrophysical aspects such as the population of black holes, properties of first stars, reionization history of the Universe, galaxy evolution and the interplay between cosmological and astrophysical effects. The meeting will also discuss future statistical tools and machine learning techniques which will be required to make robust measurements from the data which will be available from the upcoming missions on astrophysical gravitational waves, cosmic microwave background, large scale structure, line intensity mapping, supernovae and many others.

Description:
Einstein’s Equation is the corner stone of General Relativity, but in the presence of quantum matter it must be modified to make sense. Although the description of gravity as a quantum phenomenon remains very problematic, there is a wide consensus that any theory of quantum gravity should admit a semi-classical limit, where the dynamics is described by the Semi-Classical Einstein Equation (SCEE). Unfortunately this equation is fraught with mathematical difficulties and even the most basic questions about the existence and uniqueness of solutions are difficult to answer, let alone what those solutions might look like.

The purpose of this two-day meeting is to bring together experts in relevant numerical and analytical methods, in order to discuss the state of the art and future prospects for solving the Semi-Classical Einstein Equation. A public lecture by Chris Fewster (University of York) will showcase some topics closely related to the theme of the meeting.

XII Black Holes Workshop, Guimaraes, Portugal

This is the first announcement for the Black Holes Workshop XII, which will take place in Guimaraes, Portugal, in December 19-20, 2019.

From astrophysics to high-energy physics, from information theory to quantum gravity, black holes have acquired an ever increasing role in fundamental physics, and are now part of the terminology of many important branches of observational, theoretical, and mathematical physics.

The Black Holes Workshops gather researchers working on physical and mathematical problems of black holes, both in its classical and quantum aspects, as well as their connections to general relativity and gravitation, string theory, cosmology, and astrophysics, and stimulate the interaction between all these fields.

The 2019 edition celebrates two decisive dates in the history of general relativity: First, the one hundred years of the deflection of light observations by Eddington, Dyson and collaborators; second, the eighty years of the paper by Oppenheimer and Snyder showing, for the first time, the formation of black holes through gravitational collapse.

The Black Holes Workshops are informal meetings. They consist of contributed talks by the participants. There is no registration fee.

There will be a social dinner on Thursday, December 19, evening.

We kindly invite you to register and submit your contribution at the
meeting’s webpage http://w3.math.uminho.pt/bhw19.

Please forward this message to all interested colleagues.

We hope to see you in Guimaraes!
