DESCRIPTION:Seminar Physique Mathématique\n	ONLY ON ZOOM\n\nTitle: Dynamics 
 of symmetry-resolved entanglement measures in free fermionic systems\n\nAb
 stract: The presence of a global internal symmetry in a quantum many-body 
 system is reflected in the fact that the entanglement between its subparts
  is endowed with an internal structure\, namely it can be decomposed as su
 m of contributions associated to each symmetry sector. The study of the sy
 mmetry resolution of entanglement measures provides a formidable tool to p
 robe the out of- equilibrium dynamics of quantum systems.\n	\n	In this talk 
 I will present the results of a series of works\, done in collaboration wi
 th Gilles Parez and under the supervision of Prof. Pasquale Calabrese\, de
 voted to the study of the dynamics of three different symmetry-resolved en
 tanglement measures after a global quantum quench\, namely the entanglemen
 t entropy\, the mutual information and the negativity.\n	\n	In the context o
 f free fermions\, we are able to provide analytical results for the releva
 nt time-dependent quantities. In particular\, we find that entanglement en
 tropies\, mutual information and logarithmic negativity show effective equ
 ipartition in the scaling limit of large time and subsystem size. Moreover
 \, we argue that these phenomena occur in more general quantum systems\, a
 s they can be understood from the quasiparticle picture for the spreading 
 of entanglement in integrable models.\n
