Sonic horizons and causality in the phase transition dynamics
Debasis Sadhukhan, Aritra Sinha, Anna Francuz +4
A system gradually driven through a symmetry-breaking phase transition is subject to the Kibble-Zurek mechanism (KZM). As a consequence of the critical slowing down, its state cann…
Open System Tensor Networks and Kramers' Crossover for Quantum Transport
Gabriela Wojtowicz, Justin E. Elenewski, Marek M. Rams +1
Tensor networks are a powerful tool for many-body ground states with limited entanglement. These methods can nonetheless fail for certain time-dependent processes - such as quantum…
Universal shift of the fidelity susceptibility peak away from the critical point of the Berezinskii-Kosterlitz-Thouless quantum phase transition
Lukasz Cincio, Marek M. Rams, Jacek Dziarmaga +1
We show that the peak which can be observed in fidelity susceptibility around the Berezinskii-Kosterlitz-Thouless transition is shifted from the quantum critical point (QCP) at $J_…
Symmetry breaking bias and the dynamics of a quantum phase transition
Marek M. Rams, Jacek Dziarmaga, Wojciech H. Zurek
The Kibble-Zurek mechanism predicts the formation of topological defects and other excitations that quantify how much a quantum system driven across a quantum critical point fails…
Breaking the entanglement barrier: Tensor network simulation of quantum transport
Marek M. Rams, Michael Zwolak
The recognition that large classes of quantum many-body systems have limited entanglement in the ground and low-lying excited states led to dramatic advances in their numerical sim…
Brute-forcing spin-glass problems with CUDA
Konrad Jałowiecki, Marek M. Rams, Bartłomiej Gardas
We demonstrate how to compute the low energy spectrum for small (), but otherwise arbitrary, spin-glass instances using modern Graphics Processing Units or similar heterog…
