Thermometry of strongly correlated fermionic quantum systems using impurity probes
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
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 …

Criticality revealed through quench dynamics in the lipkin-meshkov-glick model
S Campbell - Physical Review B, 2016 - APS
We examine the dynamics after a sudden quench in the magnetic field of the Lipkin-
Meshkov-Glick model. Starting from the ground state and by employing the time-dependent …
