The „Magic Barrier” and other news from Hamiltonian lattice gauge theory
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.
