SUMMARY:Time-evolution of local information : thermalization dynamics of local observables (Loïc Herviou / LPT / Seminar). - 3/12\, 11H.
DESCRIPTION:Loïc Herviou (EPFL\, Lausanne) \nAbstract : Understanding thermalization in closed quantum mechanics remains a subtle problem. As the occupancies of the Hamiltonian eigenstates are conserved\, thermalization occurs when eigenstates close in energy share similar local observables. In this talk\, I will discuss thermalization through the point of view of information. I will introduce a concept of information lattice\, which allows to represent the information flow using locality as an additional dimension. Thermalization then corresponds to a flow of the state specific information to a non-local range. Based on this observation\, I will propose a tentative algorithm that allows to simulate large scale dissipative systems at long times. \n  \n\n  \n

SUMMARY:Spin-Orbit Physics at Magnetic Interfaces (Aurélien Manchon / LPT / Seminar). - 7/12\, 14 H.
DESCRIPTION:Aurélien Manchon (CINaM\, Université d’Aix-Marseille) \nMagnetic materials lacking inversion symmetry constitute a unique platform for the exploration and control of magnetism. In these systems\, typically multilayers of transition metal ferromagnets and heavy metals (W\, Pt\, Bi2Se3 etc.)\, interfacial spin-orbit coupling promotes a wealth of physical phenomena\, among which the emergence of magnetic skyrmions\, spin-to-charge conversion\, spin-orbit torques\, as well as chiral magnetic damping. In this presentation\, I will first discuss the nature of interfacial spin-orbit coupling in magnetic multilayers and examine how it promotes spin-orbit torques. I will review various key aspects of this torque (symmetries and physical origin) and will discuss in particular a newly discovered component that allows for field-free switching. In a second part\, I will discuss how this torque can be used to electrically manipulate and excite antiferromagnetic materials\, a class of materials that can support ultrafast THz excitations.

SUMMARY:Hydrodynamics of the one-dimensional Bose gas : atom losses (Jerôme Dubail / LPT / Seminar). - 14/12\, 14H.
DESCRIPTION:Jerôme Dubail (LPCT\, Nancy) \nI will briefly introduce “Generalized Hydrodynamics”\, the hydrodynamic description of one-dimensional integrable systems [1\,2]\, and review the experimental results [3\,4] obtained by the groups of I. Bouchoule in Palaiseau and D. Weiss in Penn State. One important experimental effect not taken into account in GHD is the atom losses : I will discuss perspectives on how to include these [5\,6\,7]. \n[1] O. Castro-Alvaredo\, B. Doyon\, T.
