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 …
