CA18108 Action participant Prof. Nikolaos Mavromatos receives the 2023 John William Strutt, Lord Rayleigh Medal and Prize

We are proud to announce that Prof. Nikolaos (‘Nick’) Mavromatos (King’s College London and National Technical University of Athens) has received the prestigious John William Strutt, Lord Rayleigh Medal and Prize, awarded by the Institute of Physics (IOP) to those whose distinguished contributions have helped advance the field of theoretical, including computational and mathematical, physics. The 2023 edition of this prize recognizes Professor Nikolas Mavromatos “for fundamental contributions to theoretical physics, especially the suggestion of quantum gravity-induced modifications of the vacuum optical properties, a proposition that led to a new arena of theoretical and experimental investigation.”

The active role played by Prof. Mavromatos in CA18108 activities has been essential for the success of our Action. Congratulations, Nick!

CosmoNag-ICN

Celia Escamilla-Rivera (Instituto de Ciencias Nucleares, Universidad Autonoma de Mexico) and Geovanny Rave (Escamilla’s master’s student) were awarded Honorable Mention in the 2023 Essay Competition of the Gravity Research Foundation for their essay “On primordial gravitational waves in Teleparallel Gravity”, https://arxiv.org/abs/2305.06987

Laurent Freidel (Perimeter Institute for Theoretical Physics, Canada), Jerzy Kowalski-Glikman (University of Wroclaw, Poland), Robert G. Leigh (University of Illinois, USA), and Djordje Minic (Virginia Tech, USA) were awarded Honorable Mention in the 2023 Essay Competition of the Gravity Research Foundation for their essay “On the Inevitable Lightness of Vacuum”, https://arxiv.org/abs/2303.17495

which presents a new understanding of the cosmological constant problem.

Carlos Sopuerta (Institute of Space Sciences (ICE) of the National Spanish, Research Council (CSIC), Bellaterra, Barcelona, Spain), together with his colleagues José Luis Jaramillo (Institut de Mathématiques de Bourgogne (IMB), Université de Bourgogne Franche-Comté, Dijon, France) and Badri Krishnan (Institute of Mathematics, Astrophysics and Particle Phyiscs, Radboud University, Nijmegen, Netherlands), were awarded Honorable Mention in the 2023 Essay Competition of the Gravity Research Foundation for their essay “Universality in Binary Black Hole Dynamics: An Integrability Conjecture”, https://arxiv.org/abs/2305.08554,

where they deepen in the simplicity and universality of the waveform
of a binary black hole coalescence.

Carlos Barceló Serón (Author of La gravedad)

Julio Arrechea and Carlos Barceló (Institute of Astrophysics of
Andalusia) have been awarded an Honorable Mention
in the 2023 Gravity Research Foundation Awards for Essays on Gravitation
with their essay titled “Stellar equilibrium on
a physical vacuum soil” (https://arxiv.org/abs/2305.07939). This essay
explores the relevance of the quantum vacuum as a key aspect behind the
existence of new figures of stellar equilibrium.

Congratulations to all of them!

COST CA18108 3rd Training School in Pałac Wojanów (Poland), 12-21 February 2023

Our 3rd Training School will be organized by the Institute of Theoretical Physics of the University of Wroclaw at Pałac Wojanów, situated in the neighborhood of Jelenia Góra (Poland), from the 12th to the 21st February 2023. Registration is open at the website of the School:

https://indico.capa.unizar.es/event/30/

where you can find additional information about the organization of the school.

We encourage the participation of PhD students and young postdocs with either theoretical or experimental background, since one of the objectives of the Action is the training of young researchers in theoretical models and experimental techniques in order to build a new scientific profile that will combine the relevant skills and a transversal background in the fields of astrophysics and quantum gravity.

IceCube probes for quantum gravity using astrophysical neutrino flavors

The IceCube Collaboration, which includes members from our COST Action CA18108, has presented the results of its search for the effect of quantum gravity on the flavors of astrophysical neutrinos. Although no evidence was found for quantum gravity effects, the result presented is the first to reach the expected signal region of quantum gravity using neutrino flavor interferometry. This study was published today as a letter in the journal Nature Physics.
