Séminaire du LPTMS : Pierfrancesco Urbani (IPHT)
Marginal stability in soft anharmonic mean field spin glasses
Pierfrancesco Urbani (Institut de Physique Théorique)
Onsite blackboard talk + zoom (zoom ID:995 6963 5229, pw: M6Z5ib).
I will consider simple mean field spin glasses of real degrees of freedom subjected to anharmonic quartic potential and study the glass phase. I will show how this phase realizes marginal stability through soft, pseudogapped, non-linear excitations. I will also discuss how these findings provide a new scenario for the longstanding problem of the spin glass transition in a field and why this is important for the physics of low temperature amorphous solids.
