Post-Doc Position in GAST Perugia-Brescia team starting from Fall 2024
The Gauge Theories and Strings (GAST) group in Perugia-Brescia invites applications for an INFN postdoctoral position starting in fall 2024, on the topic of “Holographic dualities, quantum information and gravity”. The appointment will last two years and the actual work place will be Brescia (contact persons Roberto Auzzi and Giuseppe Nardelli). Eligible candidates should be non-Italian citizens, or Italian citizens who, at the submission deadline, hold a position in a foreign institution and have been continuously abroad for at least three years. Applications should be sumbitted not later than November 10, 2023 (11:59 a.m. CET). Notice that it is mandatory to apply through the website: https://reclutamento.dsi.infn.it/ [search for call (“bando”) n. 25864]. The official call, containing the complete information and requirements, is available at https://jobs.dsi.infn.it/dettagli_job.php?id=3744.
Post-Doc position: 1+1 years funded by INFN (two years in total)
Brescia/Perugia team in Brief
Members:
Brescia: Roberto Auzzi and Giuseppe Nardelli (staff, Università Cattolica del Sacro Cuore and INFN sezione di Perugia)
Perugia: Gianluca Grignani and Marta Orselli (staff, Università degli Studi di Perugia and INFN sezione di Perugia) Andrea Placidi (postdoc, INFN sezione di Perugia) Marta Cocco, Elisa Grilli and Daniele Pica (PhD students, INFN sezione di Perugia).
Research Interest:
The interests of the group focusses on the relation between AdS/CFT correspondence and quantum information, in particular on the topics of entanglement entropy and on the role of computational complexity in understanding holographic dualities. An interesting direction is to try to extend the holographic approach outside the AdS comfort zone, including de Sitter and non-relativistic systems. We are also interested in applications of holographic dualities to the study of strongly coupled non-equilibrium systems and to conformal interfaces and defects.
Other research topics involve the analytical investigation of new types of strong gravitational phenomena related to the dynamics of binary black hole systems. These phenomena include, among others, binary black hole systems immersed in a background of a general curved space-time generated for example by the presence of a third body, such as a nearby supermassive black hole bound to the binary system.
Current research topics: 1) Holographic duals of asymptotically AdS spacetime including dS bubbles in the interior.2) Holographic complexity and its relation with quantum computational complexity (including Nielsen and Krylov approaches). 3) Holographic entanglement entropy in quenches and out of equilibrium systems.5) Binary Black Hole dynamics in general relativistic environments. 6) Hierarchical 3-body systems in General Relativity.
