Anomalously fast transport in non-integrable lattice gauge theories
Devendra Singh Bhakuni, Roberto Verdel, Jean-Yves Desaules +3
Kinetic constraints are generally expected to slow down dynamics in many-body systems, obstructing or even completely suppressing transport of conserved charges. Here, we show how…
Discrete solitons in Rydberg atom chains
Aron Kerschbaumer, Jean-Yves Desaules, Marko Ljubotina +1
Solitons - localized wave packets that travel without spreading - play a central role in understanding transport and properties of nonlinear systems, from optical fibers to fluid d…
Learning mixed quantum states in large-scale experiments
Matteo Votto, Marko Ljubotina, Cécilia Lancien +5
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shado…
Finding periodic orbits in projected quantum many-body dynamics
Elena Petrova, Marko Ljubotina, Gökhan Yalnız +1
Describing general quantum many-body dynamics is a challenging task due to the exponential growth of the Hilbert space with system size. The time-dependent variational principle (T…
Finite steady-state current defies non-Hermitian many-body localization
Pietro Brighi, Marko Ljubotina, Federico Roccati +1
Non-Hermitian many-body localization (NH MBL) has emerged as a possible scenario for stable localization in open systems, as suggested by spectral indicators identifying a putative…
Fragmentation, Zero Modes, and Collective Bound States in Constrained Models
Eloi Nicolau, Marko Ljubotina, Maksym Serbyn
Kinetically constrained models were originally introduced to capture slow relaxation in glassy systems, where dynamics are hindered by local constraints instead of energy barriers.…
