Normal weak eigenstate thermalization
Patrycja Łydżba, Rafał Świętek, Marcin Mierzejewski +2
Eigenstate thermalization has been numerically shown to occur for few-body observables in a wide range of nonintegrable models. For intensive sums of few-body observables, a weaker…
Local integrals of motion in dipole-conserving models with Hilbert space fragmentation
Patrycja Łydżba, Peter Prelovšek, Marcin Mierzejewski
Hilbert space fragmentation is an ergodicity breaking phenomenon, in which Hamiltonian shatters into exponentially many dynamically disconnected sectors. In many fragmented systems…
Critical quantum dynamics of observables at eigenstate transitions
Simon Jiricek, Miroslav Hopjan, Patrycja Łydżba +2
It is an outstanding goal to unveil the key features of quantum dynamics at eigenstate transitions. Focusing on quadratic fermionic Hamiltonians that exhibit localization transitio…
Single-quasiparticle eigenstate thermalization
Piotr Tokarczyk, Lev Vidmar, Patrycja Łydżba
Quadratic Hamiltonians that exhibit single-particle quantum chaos are called quantum-chaotic quadratic Hamiltonians. One of their hallmarks is single-particle eigenstate thermaliza…
Generalized thermalization in quantum-chaotic quadratic Hamiltonians
Patrycja Łydżba, Marcin Mierzejewski, Marcos Rigol +1
Thermalization (generalized thermalization) in nonintegrable (integrable) quantum systems requires two ingredients: equilibration and agreement with the predictions of the Gibbs (g…
Single-particle eigenstate thermalization in quantum-chaotic quadratic Hamiltonians
Patrycja Łydżba, Yicheng Zhang, Marcos Rigol +1
We study the matrix elements of local and nonlocal operators in the single-particle eigenstates of two paradigmatic quantum-chaotic quadratic Hamiltonians; the quadratic Sachdev-Ye…
Entanglement in many-body eigenstates of quantum-chaotic quadratic Hamiltonians
Patrycja Łydżba, Marcos Rigol, Lev Vidmar
In a recent Letter [Phys. Rev. Lett. 125, 180604 (2020)], we introduced a closed-form analytic expression for the average bipartite von Neumann entanglement entropy of many-body ei…
Eigenstate Entanglement Entropy in Random Quadratic Hamiltonians
Patrycja Łydżba, Marcos Rigol, Lev Vidmar
The eigenstate entanglement entropy has been recently shown to be a powerful tool to distinguish integrable from generic quantum-chaotic models. In integrable models, a unique feat…
