Classification of Rational Conformal Field Theories With A Single Critical Exponent (Dr. Suni Mukhi, CERN and IISER, Pune)) @ 501 e su zoom
Mar 16@2:00 pm–3:00 pm

Seminario di Fisica Teorica –

I will present the classification of all unitary, rational conformal field theories with one non-trivial primary and central charge c < 25. (with Brandon Rayhaun, arXiv: 2208.05486). I will also, more briefly, review a partial classification of theories with two nontrivial primaries, as well as some new predictions on the existence of meromorphic CFT with central charge 32.

Relaxed hydrodynamics (in an electric field) (Daniel Brattan) @ Aula 603 e zoom
Mar 22@2:00 pm–3:00 pm

Seminario di Fisica Teorica –

Hydrodynamics is the effective theory that governs the transport of charge, energy and momentum at late times and large distances. In certain circumstances this description must be modified to include the fact that these charges decay very slowly; for example when there are chemical processes or spatial translation invariance is broken. In this talk I will primarily discuss how to incorporate such “relaxation” processes into the effective theory of a fluid driven by an electric field. Given sufficient time I will place this work in the larger context of the relaxed hydrodynamics programme and tease new results.

Axion dark matter in the sky (Marco Regis, Università di Torino) @ Aula 603 e zoom
Mar 29@2:00 pm–3:00 pm

Seminario di Fenomenologia –

Axion-like particles (ALPs) are one of the most attractive solutions to the dark matter issue.
In this talk, I will discuss how to search for ALPs in astrophysical structures.
After some introduction, I will focus on the emission associated with their decay into photons.
The discussion will involve different ALP mass ranges and wavelength bands.

Emergent Fractons (Daniele Musso, Oviedo University) @ 603 e online
Apr 5@2:00 pm–3:00 pm

Seminario di Fisica Teorica –

This talk revolves about low-energy effective field theories with fractonic degrees of freedom characterised by mobility constraints. The fractonic features descend from spatially-dependent rigid symmetries, like sub-system symmetries and multipole symmetries. We focus mainly on the emergence of fractonic dynamics in standard elastic theory and generalization thereof. Elastic defects behave at low energy as fractons and they can be described as the charged objects of a dual gauge theory through Hubbard-Stratonovich duality. We propose to formulate such dual gauge theory purely in terms of standard vector gauge fields, as opposed to the customary formulation in terms of tensor gauge fields. The new formulation is promising in view of addressing some fundamental open questions related to the coupling of fractonic theories to a background geometry, relevant for their theoretical consolidation as well as for applications. If time allows, we also comment on the relation of fractons with dynamical breaking of translation symmetry and the possibility to UV complete some known fractonic models.
