In and out of equilibrium quantum metrology with mean-field quantum criticality

10 May 2020 Wald Sascha Moreira Saulo V. Semião Fernando L.

We study the influence that collective transition phenomena have on quantum metrological protocols. The single spherical quantum spin (SQS) serves as stereotypical toy model that allows analytical insights on a mean-field level... (read more)
