Recurrence analysis of quantum many-body dynamics
Tomasz Szołdra, Matheus S. Palmero, Peter Schmelcher
Observables of out-of-equilibrium quantum many-body systems display complex temporal behavior that encodes the underlying physical mechanisms but typically resists straightforward…
Catching thermal avalanches in the disordered XXZ model
Tomasz Szołdra, Piotr Sierant, Maciej Lewenstein +1
We study the XXZ model with a random magnetic field in contact with a weakly disordered spin chain, acting as a finite thermal bath. We revise Fermi's golden rule description of th…
Femtosecond pulse parameter estimation from photoelectron momenta using machine learning
Tomasz Szołdra, Marcelo F. Ciappina, Nicholas Werby +4
Deep learning models have provided huge interpretation power for image-like data. Specifically, convolutional neural networks (CNNs) have demonstrated incredible acuity for tasks s…
Tracking locality in time evolution of disordered systems
Tomasz Szołdra, Piotr Sierant, Maciej Lewenstein +1
Using local density correlation functions for a one-dimensional spin system, we introduce a correlation function difference (CFD) which compares correlations on a given site betwee…
Unsupervised detection of decoupled subspaces: many-body scars and beyond
Tomasz Szołdra, Piotr Sierant, Maciej Lewenstein +1
Highly excited eigenstates of quantum many-body systems are typically featureless thermal states. Some systems, however, possess a small number of special, low-entanglement eigenst…
Detecting ergodic bubbles at the crossover to many-body localization using neural networks
Tomasz Szoldra, Piotr Sierant, Korbinian Kottmann +2
The transition between ergodic and many-body localized phases is expected to occur via an avalanche mechanism, in which \emph{ergodic bubbles} that arise due to local fluctuations…
Determination of Chern numbers with a phase retrieval algorithm
Tomasz Szołdra, Krzysztof Sacha, Arkadiusz Kosior
Ultracold atoms in optical lattices form a clean quantum simulator platform which can be utilized to examine topological phenomena and test exotic topological materials. Here we pr…
