One-Body Purity, Non-Gaussianity, and Entanglement in Interacting Integrable Models
Rafał Świętek, Maksymilian Kliczkowski, Lev Vidmar +1
When describing entanglement in typical midspectrum eigenstates of many-body lattice Hamiltonians, two paradigms have emerged that capture the behavior observed in integrable and n…
Information in Many-body Eigenstates: A Question of Learnability
Maksymilian Kliczkowski, Jarosław Pawłowski, Masudul Haque
To what extent do individual eigenstates encode information about their parent Hamiltonian, and how does this encoding vary across the spectrum? We introduce \emph{learnability} as…
Fading ergodicity and quantum dynamics in random matrix ensembles
Rafał Świętek, Maksymilian Kliczkowski, Miroslav Hopjan +1
Recent work has proposed fading ergodicity as a mechanism for many-body ergodicity breaking. Here, we show that two paradigmatic random matrix ensembles -- the Rosenzweig-Porter mo…
Probing frustrated spin systems with impurities
Maksymilian Kliczkowski, Jakub Grabowski, Maciej M. Maśka
We investigate the effective interaction between two localized spin impurities embedded in a frustrated spin-1/2 Heisenberg chain. Treating the impurity spins as clas…
Fading ergodicity
Maksymilian Kliczkowski, Rafał Świętek, Miroslav Hopjan +1
Eigenstate thermalization hypothesis (ETH) represents a breakthrough in many-body physics since it allows to link thermalization of physical observables with the applicability of r…
Autoencoder-based analytic continuation method for strongly correlated quantum systems
Maksymilian Kliczkowski, Lauren Keyes, Sayantan Roy +4
The single particle Green's function provides valuable information on the momentum and energy-resolved spectral properties for a strongly correlated system. In large-scale numerica…
Average entanglement entropy of midspectrum eigenstates of quantum-chaotic interacting Hamiltonians
M. Kliczkowski, R. Świętek, L. Vidmar +1
To which degree the average entanglement entropy of midspectrum eigenstates of quantum-chaotic interacting Hamiltonians agrees with that of random pure states is a question that ha…
