Spectral response of disorder-free localized lattice gauge theories
Nilotpal Chakraborty, Markus Heyl, Petr Karpov +1
We show that certain lattice gauge theories exhibiting disorder-free localization have a characteristic response in spatially averaged spectral functions: a few sharp peaks combine…
Anomalous relaxation of density waves in a ring-exchange system
Pranay Patil, Markus Heyl, Fabien Alet
We present the analysis of the slowing down exhibited by stochastic dynamics of a ring-exchange model on a square lattice, by means of numerical simulations. We find the preservati…
Making Trotterization adaptive and energy-self-correcting for NISQ devices and beyond
Hongzheng Zhao, Marin Bukov, Markus Heyl +1
Simulation of continuous time evolution requires time discretization on both classical and quantum computers. A finer time step improves simulation precision, but it inevitably lea…
Disorder-free localization transition in a two-dimensional lattice gauge theory
Nilotpal Chakraborty, Markus Heyl, Petr Karpov +1
Disorder-free localization is a novel mechanism for ergodicity breaking which can occur in interacting quantum many-body systems such as lattice gauge theories (LGTs). While the na…
