Coherent and dissipative dynamics at quantum phase transitions

D Rossini, E Vicari - Physics Reports, 2021 - Elsevier
The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

Thermometry of strongly correlated fermionic quantum systems using impurity probes

G Mihailescu, S Campbell, AK Mitchell - Physical Review A, 2023 - APS
We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

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 …
