Diffusion from Convection
Marko Medenjak, Jacopo De Nardis, Takato Yoshimura
We introduce non-trivial contributions to diffusion constant in generic many-body systems arising from quadratic fluctuations of ballistically propagating, i.e. convective, modes.…
Domain wall melting in spin-1 chains
Marko Medenjak, Jacopo De Nardis
In this letter we study the non-equilibrium spin dynamics in the non-integrable spin-1 XXZ chain, emerging after joining two macroscopic pure states with different magnetizations.…
The isolated Heisenberg magnet as a quantum time crystal
Marko Medenjak, Berislav Buca, Dieter Jaksch
We demonstrate analytically and numerically that the paradigmatic model of quantum magnetism, the Heisenberg XXZ spin chain, does not relax to stationarity and hence constitutes a…
Two-species hardcore reversible cellular automaton: matrix ansatz for dynamics and nonequilibrium stationary state
Marko Medenjak, Vladislav Popkov, Tomaž Prosen +2
In this paper we study the statistical properties of a reversible cellular automaton in two out-of-equilibrium settings. In the first part we consider two instances of the initial…
Anomalous spin diffusion in one-dimensional antiferromagnets
Jacopo De Nardis, Marko Medenjak, Christoph Karrasch +1
The problem of characterizing low-temperature spin dynamics in antiferromagnetic spin chains has so far remained elusive. We reinvestigate it by focusing on isotropic antiferromagn…
Operator Entanglement in Interacting Integrable Quantum Systems: the Case of the Rule 54 Chain
Vincenzo Alba, Jerome Dubail, Marko Medenjak
In a many-body quantum system, local operators in Heisenberg picture spread as time increases. Recent studies have attempted to find features of tha…
