Scale-invariant survival probability at eigenstate transitions

M Hopjan, L Vidmar - Physical Review Letters, 2023 - APS
Understanding quantum phase transitions in highly excited Hamiltonian eigenstates is
currently far from being complete. It is particularly important to establish tools for their …

Critical quantum dynamics of observables at eigenstate transitions

S Jiricek, M Hopjan, P Łydżba, F Heidrich-Meisner… - Physical Review B, 2024 - APS
It is an outstanding goal to unveil the key features of quantum dynamics at eigenstate
transitions. Focusing on quadratic fermionic Hamiltonians that exhibit localization transitions …

Detecting delocalization-localization transitions from full density distributions

M Hopjan, G Orso, F Heidrich-Meisner - Physical Review B, 2021 - APS
Characterizing the delocalization transition in closed quantum systems with a many-body
localized phase is a key open question in the field of nonequilibrium physics. We exploit the …

Coexistence of one-dimensional and two-dimensional topology and genesis of Dirac cones in the chiral Aubry-André model

TVC Antão, DA Miranda, NMR Peres - Physical Review B, 2024 - APS
We construct a one-dimensional (1D) topological SSH-like model with chiral symmetry and a
superimposed hop** modulation, which we call the chiral Aubry-André model. We show …

[HTML][HTML] Survival probability, particle imbalance, and their relationship in quadratic models

M Hopjan, L Vidmar - Entropy, 2024 - mdpi.com
We argue that the dynamics of particle imbalance in quadratic fermionic models is, for the
majority of initial many-body product states in the site occupation basis, virtually …
