Reminder: CFP: Information-Theoretic Concepts in Physics
by Michael Cuffaro March 30, 2023

March 30, 2023

Call for papers: Special issue of Entropy **Information-Theoretic Concepts in Physics** Guest editors: ----- Michael Cuffaro (LMU Munich) Stephan Hartmann (LMU Munich) Deadline for manuscript submissions: ----- 1 May 2023 Description: ----- Information-theoretic concepts are becoming increasingly important in physics, both in applied and theoretical physics. Examples include using quantum-mechanical systems to perform computations and transmit information; the use of information-theoretic concepts to characterize gravitational phenomena, such as black holes; informational axiomatizations and interpretations of quantum theory; and many others. The goal of this Special Issue is to provide an interdisciplinary snapshot of the foundational and philosophical research at the cutting edge of this important area of physics. We welcome submissions focused on topics such as (but not restricted to): - Historical perspectives on the use of informational concepts in physics; - Quantum and classical information; - Quantum and classical computational resources; - Informational interpretations and axiomatizations of physical theories; - Informational approaches to spacetime phenomena; - Informational characterizations of thermodynamical phenomena and the thermodynamics of information; - Informational characterizations of open systems phenomena; - General methodological and philosophical issues related to the physics of information. Manuscript submission information: ----- Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, the submission form can be accessed here: https://susy.mdpi.com/user/manuscripts/upload/?journal=entropy. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website. Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page (https://www.mdpi.com/journal/entropy/instructions) Entropy (https://www.mdpi.com/journal/entropy) is an international peer-reviewed open access monthly journal published by MDPI. Please visit the Instructions for Authors page (https://www.mdpi.com/journal/entropy/instructions) before submitting a manuscript. The Article Processing Charge (APC) (https://www.mdpi.com/about/apc/) for publication in this open access (https://www.mdpi.com/about/openaccess/) journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service (https://www.mdpi.com/authors/english) prior to publication or during author revisions.

Invitation to join a research project on the very nature of gravitation
by vpetkov＠minkowskiinstitute.org March 24, 2023

March 24, 2023

Minkowski Institute is inviting colleagues who are interested in joining (as affiliated members of the Institute) its most ambitious research project – to examine rigorously whether gravitational phenomena are noting more than manifestations of the non-Euclidean geometry of spacetime, which would mean that gravitation is not a physical interaction. This project follows strictly Minkowski’s program of geometrizing Physics – after discovering the spacetime structure of the world (all physical objects are, in reality, a forever given web of worldlines in spacetime), Minkowski summarized this program: “The whole world presents itself as resolved into such worldlines, and I want to say in advance, that in my understanding the laws of physics can find their most complete expression as interrelations between these worldlines.” Colleagues who join the project will take part in analyzing the mathematical structure of general relativity with the explicit intention to derive, following Minkowski’s program, all predictions of general relativity by regarding gravitational phenomena as effects of the non-Euclidean geometry of spacetime, without assuming that gravitation is a physical interaction (i.e., without assuming the existence of gravitational energy and momentum). In 1921 Eddington mentioned the possibility that gravitation might not be a physical interaction almost explicitly – “gravitation as a separate agency becomes unnecessary” [A. S. Eddington, The Relativity of Time, Nature 106, 802-804 (17 February 1921)]. The main theme of the Third Hermann Minkowski Meeting on the Foundations of Spacetime Physics this year (https://minkowskiinstitute.org/meetings/2023/) will be the nature of gravitation – whether it is merely spacetime geometry or it is a physical interaction. If interested, contact us at mi(a)minkowskiinstitute.org or by responding to this message.

Fwd: Black Hole and Gravitational Wave Day in Munich, May 12
by Erik Curiel March 22, 2023

March 22, 2023

May be of interest to some of y'all... ---------- Forwarded message --------- From: *Torsten Enßlin* <ensslin(a)mpa-garching.mpg.de <mailto:ensslin@mpa-garching.mpg.de>> Date: Mon, Mar 20, 2023 at 11:06 AM Subject: [ift-group] Fwd: Black Hole and Gravitational Wave Day in Munich, May 12 Dear colleagues, We are happy to announce the “*Black Hole and Gravitational Wave Day*” to bring everyone working on topics related to cosmological and astrophysical gravitational waves and all aspects related to black holes in the Munich area together. The event will be held in person on Friday May 12 at the MPA seminar room, and we welcome all interested participants to join. The aim is to connect the many researchers working in the Munich area. Topics will include: - Primordial Black Holes - Black Holes (theory + observation) - Gravitational Waves (stochastic backgrounds, astrophysical sources, early Universe, B-modes, …) We aim for a mix of invited talks, lively discussion sessions and many contributions from locals, so we encourage everyone who is interested to submit a talk title or an abstract. We especially encourage PhD students and early career researchers to apply. Confirmed speakers include Reinhard Genzel (MPE), Selma de Mink (MPA), Gia Dvali (LMU), and Günther Hasinger (ESA, tbc). You can find the event page here: https://indico.ph.tum.de/event/7265/ <https://indico.ph.tum.de/event/7265/> Please, register if you want to attend and note that*the deadline for the submission of contributions is April 12*. We are looking forward to meeting all of you! Feel free to circulate this email within your own research groups to help reach everyone interested in Munich. Best regards, Mathias Garny, Valeriya Korol, Florian Kühnel, Henrique Rubira, Julia Stadler
