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…
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…
Light-induced quantum droplet phases of lattice bosons in multimode cavities
P. Karpov, F. Piazza
Multimode optical cavities can be used to implement interatomic interactions which are highly tunable in strength and range. For bosonic atoms trapped in an optical lattice, cavity…
Spatiotemporal dynamics of particle collisions in quantum spin chains
P. I. Karpov, G. -Y. Zhu, M. P. Heller +1
Recent developments have highlighted the potential of quantum spin models to realize the phenomenology of confinement leading to the formation of bound states such as mesons. In th…
Variational classical networks for dynamics in interacting quantum matter
Roberto Verdel, Markus Schmitt, Yi-Ping Huang +2
Dynamics in correlated quantum matter is a hard problem, as its exact solution generally involves a computational effort that grows exponentially with the number of constituents. W…
Disorder-free localization in an interacting two-dimensional lattice gauge theory
P. Karpov, R. Verdel, Y. -P. Huang +2
Disorder-free localization has been recently introduced as a mechanism for ergodicity breaking in low-dimensional homogeneous lattice gauge theories caused by local constraints imp…
Modeling of networks and globules of charged domain walls observed in pump and pulse induced states
Petr Karpov, Serguei Brazovskii
Experiments on optical and STM injection of carriers in layered materials revealed the formation of nanoscale patterns with networks and globules of domain walls. T…
Polarizability of electrically induced magnetic vortex plasma
P. I. Karpov, S. I. Mukhin
Electric field control of magnetic structures, particularly topological defects in magnetoelectric materials, draws a great attention in recent years, which has led to experimental…
Phase transitions in ensembles of solitons induced by an optical pumping or a strong electric field
P. Karpov, S. Brazovskii
The latest trend in studies of modern electronically and/or optically active materials is to provoke phase transformations induced by high electric fields or by short (femtosecond)…
Dielectric susceptibility of magnetoelectric thin films with vortex-antivortex dipole pairs
P. I. Karpov, S. I. Mukhin
We consider model of quasi-2D magnetoelectric material as XY model for spin system on a lattice with local multiferroic-like interaction of spin and electric polarization vectors.…
