Assessment of weak-coupling approximations on a driven two-level system under dissipation
Wallace S. Teixeira, Fernando L. Semião, Jani Tuorila +1
The standard weak-coupling approximations associated to open quantum systems have been extensively used in the description of a two-level quantum system, qubit, subjected to relati…

In and out of equilibrium quantum metrology with mean-field quantum criticality
Sascha Wald, Saulo V. Moreira, Fernando L. Semião
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 a…
