Fourth European Physical Society Conference on Gravitation: Black Holes, Valencia, Spain --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26927 Starting: 2023-11-13 to 2023-11-15 Location: Valencia, Spain Additional Information: https://congresos.adeituv.es/4epsgpd/ficha.en.html Contact: j.antonio.font[AT]uv.es The 4th European Physical Society Conference on Gravitation, organised by the Gravitational Physics Division, will be held in person in Valencia (Spain) on November 13-15, 2023. The aim of the conference is to showcase the rich landscape of current research in black hole physics and to stimulate exchange of ideas and discussion among the participants. Once regarded as a mathematical curiosity of Einstein's general relativity, the importance of black holes in fundamental physics is now incontrovertible. Black holes play a prominent role across many branches of physics, from astrophysics and cosmology to high-energy physics, from information theory to quantum gravity. Many such aspects of black hole physics will be covered at the 4th EPS Conference on Gravitation, and from a theoretical, observational and phenomenological perspective. The conference is organised in three days, each one focused around three key topics - theory, observations, phenomenology - introduced by invited speakers and contributed talks followed by round table discussions. There will also be a poster session. The scientific program will be finalised in the upcoming weeks. The conference will take place at ADEIT, the University-Enterprise Foundation of the University of Valencia. Registration to the conference is already opened and will end on October 27th. Submission of abstracts for contributed talks or posters is also opened and will close on October 16. The registration fee for the conference is 50 EUR. The fee includes access to all sessions, all coffee breaks and lunches, the Monday Welcome cocktail, the conference dinner, and the certificate of participation issued online. With my best regards. Toni Font (for the LOC/SOC). +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.3.

Postdoctoral position in Mathematical Physics, Sheffield, UK ------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/07/10/postdoctoral-position-in-math... Deadline: 2023-07-26 Location: Sheffield, UK Additional Information: https://shorturl.at/afnX3 Contact: s.dolan[AT]sheffield.ac.uk Research Associate in Mathematical Physics (University of Sheffield, UK). Duration: 12 months. Salary: Grade 7, GBP 36,333 pa. Job application link: https://shorturl.at/afnX3    Job reference: <span style="color: var(--nv-text-color);font-family: var(--bodyfontfamily);font-size: var(--bodyfontsize);letter-spacing: var(--bodyletterspacing);text-transform: var(--bodytexttransform);background-color: var(--nv-site-bg)">UOS037707</span> Closing date: 26th July 2023. This postdoctoral position arises from a recently awarded STFC grant "Penrose processes in an analogue black hole formed in hybrid light-matter (polariton) superfluid" in Sheffield. The researcher will work in the Cosmology and Relativity group with Dr Sam Dolan (School of Mathematics and Statistics) on topics in analogue gravity, and they will provide theoretical modelling for the experimental group led by Prof Dmitry Krizhanovskii (Department of Physics and Astronomy). The aim of the project is to recreate a Penrose-like process in a laboratory quantum system, by using exciton-polaritons in semiconductor photonic structures based on III-V semiconductors. The condensation and superfluidity of polaritons generates a large draining vortex in a superfluid, emulating the "flow" of space-time into a black hole. The experimental team aim to image the trajectories of excitations (e.g. vortices) in this flow. The theory team, to include the postdoctoral researcher, will seek to describe the motion and dynamics of excitations using tools originally developed in General Relativity, as well as through simulations of the polariton fluid. The overall success of the project hinges, first, on establishing a robust theoretical map between trajectories in the laboratory system and the worldlines of particles or strings in an effective spacetime; and, second, on showing that excitations can extract energy from the system in a way analogous to the Penrose process in the context of black holes. The contribution of the postdoctoral researcher will be essential in meeting these goals. Overall, the project addresses fundamental physics questions with state-of-the art semiconductor quantum technologies developed in the Department of Physics and Astronomy and the National Epitaxy Facility at the University of Sheffield: it relates general relativity to hydrodynamics and physics of macroscopically ordered light-matter states in solids, and it opens up new avenues in the study of quantum phenomena and gravity effects on the microscale. The successful applicant will have a PhD or equivalent experience relevant to mathematical modelling and physics. Experience of solving ordinary and partial differential equations with exact, approximation and numerical methods is essential. A background in general relativity, analogue gravity and/or modelling of quantum fluids will be highly advantageous. You must display outstanding motivation, enthusiasm and commitment to undertake research in a fast-moving, interdisciplinary and international field. You will be expected to have excellent collaboration and communication skills, and to be able to work to a high standard both independently and as part of a team, while meeting project deadlines. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2.5.

With the developed methods, you will likely be placing much more stringent bounds on fundamental constraints from third-generation detectors. You will join the international Einstein Telescope Collaboration as well as the LIGO-Virgo-KAGRA Collaboration, and are expected to participate in analysing data as part of the latter.
