Energy conditions in quantum theory and gravity, York, UK

Posted on by

The workshop “Energy conditions in quantum theory and gravity” will be held from September 20-21, 2018 at the University of York (UK) in the historic King’s Manor.

Registration is now open until September 1st. For more information and registration visit the workshop website: https://sites.google.com/a/york.ac.uk/energy-conditions-in-quantum-theory-and-gravity

Classical energy conditions were introduced as a means of codifying generic properties of matter in general relativity. They play key roles in the singularity theorems of Hawking and Penrose and in many other results of mathematical relativity. However, not all models of classical matter obey the pointwise energy conditions, and quantum fields cannot obey any of them. This workshop will address two main themes, bringing together experts in both areas: (a) the use of weakened energy conditions in classical relativity, (b) the Quantum Energy Inequalities that can be proved for various quantum field theory models, and their consequences. In addition, related topics in mathematical relativity and quantum field theory will be discussed.

This workshop also falls in the 40th anniversary year of the first paper on energy inequalities in quantum field theory. [LH Ford, Proc.Roy.Soc.Lond. A364 (1978) 227-236]

The aim of this school is to provide an in-depth overview about recent developments in the field. Starting with a precise formulation of the problem in the first half of the school, we will discuss various solution proposals, with a particular focus on the relation to the BMS-group.

Targeting mainly PhD-students, the material will be covered in form of lectures and discussion sessions.

Related contributions by attendees are also welcome.

Awards for Essays on Gravitation, 2018

Posted on by

In 2018, for our sixty-ninth competition, the trustees of the Gravity Research Foundation are offering five awards for short essays for stimulating thought and encouraging work on the phenomenon of gravitation. The stipulations follow:

(1) We will make these Awards on May 15, 2018 for the best and most well-written essays about gravitation, its theory, applications or effects. Essays should be 1500 words or fewer excluding abstracts and a small number of equations, diagrams, tables and references. The subject matter may or may not be original research. The essay competition is not intended to replace a research journal where the detailed results of original research are submitted. Essays should not give lengthy detailed mathematical calculations nor detailed descriptions of an experimental setup. Essay ideas should be self-contained and understandable – not dependent on reading other documents.

(2) The First Award will be $4000.00
The Second Award will be 1250.00
The Third Award will be 1000.00
The Fourth Award will be 750.00

(3) Essay must be in English and e-mailed in a single PDF file before April 1, 2018. One essay only will be accepted from each author. Notify us within 24 hours if you do not receive an e-mail confirmation of your submission.

(4) Title page should include: essay title, authors’ names (specify corresponding author), e-mail & mailing addresses, submission date, an abstract of 125 words or fewer, and the statement: “Essay written for the Gravity Research Foundation 2018 Awards for Essays on Gravitation.” Pages should be numbered.

(5) The decision of the judges will be final and no reviews or comments will be provided.

(6) Please check the winners’ announcement to be posted on our website: www.gravityresearchfoundation.org around May 15, 2018. We will also attempt to send all participants a general e-mail notification.

(7) The five award-winning essays will be published in a special issue of the International Journal of Modern Physics D (IJMPD). Authors of essays designated Honorable Mention will be invited to submit their essays to the IJMPD where these may undergo additional refereeing at editorial discretion for possible publication. Authors of all other essays are free and encouraged to publish their essays after May 15th.
