Dear Colleagues,

This is to announce the following seminar talk organised by the BME
Department of Theoretical Physics:

Date: June 25th Tuesday, 2024, 14:30
Location: Schay room, BME Building F, stairway I., first floor

Non-ergodicity in kinetically constrained models: localization,
fragmentation, and confinement

Strongly interacting systems are generally expected to thermalize, making
local information of the initial state scattered into highly non-local
degrees of freedom that are challenging to access. However, various
mechanisms exist that could prevent thermalization and, therefore, aid in
passively protecting coherence and quantum information.

In this talk, I will show how different ergodicity-breaking mechanisms
manifest in a single class of models, known as kinetically constrained
models, which can be realized in current platforms based on Rydberg arrays
[1] and superconducting circuits [2]. Then, I will discuss a novel dynamical
phase transition between an ergodic phase and a non-ergodic one that these
models can host, which can be diagnosed through the complexity of simulating
the dynamics using tensor networks [3].
