Resonant false vacuum decay in two dimensions on a 4000-qubit quantum annealer
Gregor Humar, Jean-Yves Desaules, Luka Pavešić +4
From cosmology to quantum matter, metastable states often decay through the nucleation and growth of competing domains, with false vacuum decay providing the paradigmatic example o…
Finite-temperature crossover from coherent magnons to energy superdiffusion in the PXP model
Shengtao Jiang, Jean-Yves Desaules, Marko Ljubotina +1
The PXP chain was recently shown to exhibit superdiffusive energy transport with Kardar-Parisi-Zhang-like scaling, , joining a growing number of spin chains with this…
Absence of thermalization of free systems coupled to gapped interacting reservoirs
Marko Ljubotina, Dibyendu Roy, Tomaž Prosen
We study the thermalization of a small chain coupled to long, gapped leads at either side by observing the relaxation dynamics of the whole system. Using extensive tenso…
Kardar-Parisi-Zhang physics in the quantum Heisenberg magnet
Marko Ljubotina, Marko Znidaric, Tomaz Prosen
Equilibrium spatio-temporal correlation functions are central to understanding weak nonequilibrium physics. In certain local one-dimensional classical systems with three conservati…
Ballistic spin transport in a periodically driven integrable quantum system
Marko Ljubotina, Lenart Zadnik, Tomaž Prosen
We demonstrate ballistic spin transport of an integrable unitary quantum circuit, which can be understood either as a paradigm of an integrable periodically driven (Floquet) spin c…
Non-equilibrium quantum transport in presence of a defect: the non-interacting case
Marko Ljubotina, Spyros Sotiriadis, Tomaž Prosen
We study quantum transport after an inhomogeneous quantum quench in a free fermion lattice system in the presence of a localised defect. Using a new rigorous analytical approach fo…
Interaction instability of localization in quasiperiodic systems
Marko Znidaric, Marko Ljubotina
Integrable models form pillars of theoretical physics because they allow for full analytical understanding. Despite being rare, many realistic systems can be described by models th…
Many-body quantum chaos: Analytic connection to random matrix theory
Pavel Kos, Marko Ljubotina, Tomaz Prosen
A key goal of quantum chaos is to establish a relationship between widely observed universal spectral fluctuations of clean quantum systems and random matrix theory (RMT). For sing…
A class of states supporting diffusive spin dynamics in the isotropic Heisenberg model
Marko Ljubotina, Marko Znidaric, Tomaz Prosen
The spin transport in isotropic Heisenberg model in the sector with zero magnetization is generically super-diffusive. Despite that, we here demonstrate that for a specific set of…
Spin diffusion from an inhomogeneous quench in an integrable system
Marko Ljubotina, Marko Znidaric, Tomaz Prosen
Generalised hydrodynamics predicts universal ballistic transport in integrable lattice systems when prepared in generic inhomogeneous initial states. However, the ballistic contrib…
