[institut] SCL Seminar: Ana Hudomal, Thursday 20 November, 14:00

[Marija Mitrovic Dankulov]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study 
of Complex Systems, which will be held on Thursday, 20 November 2025 at 
14:00 in the library reading room "Dr. Dragan Popović" of the Institute 
of Physics Belgrade. The talk entitled

Escaping Thermalization: Quantum Simulations of Many-Body Scars

will be given by Ana Hudomal (SCL, Institute of Physics Belgrade). The 
abstract of the talk:

Understanding thermalization in isolated quantum systems is one of the 
central challenges in quantum many-body physics. While the eigenstate 
thermalization hypothesis provides a general framework, an increasing 
number of exceptions are now known. One such exception is a novel class 
of systems in which a small number of non-thermal eigenstates coexist 
with an otherwise ergodic spectrum, representing a form of weak 
ergodicity breaking [1]. These atypical eigenstates, known as quantum 
many-body scars (QMBS), can lead to unexpectedly long-lived coherent 
dynamics. In this talk, I will discuss how QMBS behavior can be realized 
and explored using a variety of quantum simulators, including 
Rydberg-atom arrays, as well as Bose-Hubbard [2] and Fermi-Hubbard 
systems [3]. I will also show how certain perturbations can enhance 
scarring [4] or give rise to previously unknown non-ergodic regimes [5].
