The "Magic Barrier" and other news from Hamiltonian lattice gauge theory

 

Dátum: 2026. február 26. csütörtök, 11 óra

Helyszín: 3-as épület Tanácsterem és online

 

The Hamiltonian formulation of lattice gauge theories allows to exactly
compute dynamical processes in real time. Of particular interest are
non-perturbative processes, such as thermalization and color-string
breaking. Using SU(2) gauge theory, we show that a certain quantity related
to quantum "magic" - the quantum aspects that cannot be efficiently
implemented on classical computers - exhibits a peak that coincides with the
period of most rapid entropy growth. I will also report recent first results
for SU(3) gauge theory including the string-like potential between heavy
quarks.
