Dynamical and excited-state quantum phase transitions in collective systems

ÁL Corps, A Relaño - Physical Review B, 2022 - APS
We study dynamical phase transitions (DPTs) in quantum many-body systems with infinite-
range interaction, and present a theory connecting the two kinds of known DPTs (sometimes …

Dynamical quantum phase transitions in non-Hermitian lattices

L Zhou, Q Wang, H Wang, J Gong - Physical Review A, 2018 - APS
In closed quantum systems, dynamical phase transitions are identified by the nonanalytic
behavior of the return probability as a function of time. In this work, we study the nonunitary …

Quench dynamics and zero-energy modes: The case of the Creutz model

R Jafari, H Johannesson, A Langari… - Physical Review B, 2019 - APS
In most lattice models, the closing of a band gap typically occurs at high-symmetry points in
the Brillouin zone. Differently, in the Creutz model—describing a system of spinless fermions …

Dynamical quantum phase transitions: A geometric picture

J Lang, B Frank, JC Halimeh - Physical review letters, 2018 - APS
The Loschmidt echo is a purely quantum-mechanical quantity whose determination for large
quantum many-body systems requires an exceptionally precise knowledge of all eigenstates …

Theory of dynamical phase transitions in quantum systems with symmetry-breaking eigenstates

ÁL Corps, A Relaño - Physical review letters, 2023 - APS
We present a theory for the two kinds of dynamical quantum phase transitions, termed DPT-I
and DPT-II, based on a minimal set of symmetry assumptions. In the special case of …

Dissipative time crystals with long-range Lindbladians

G Passarelli, P Lucignano, R Fazio, A Russomanno - Physical Review B, 2022 - APS
Dissipative time crystals can appear in spin systems, when the Z 2 symmetry of the
Hamiltonian is broken by the environment, and the square of total spin operator S 2 is …
