Optimal observables for quantum-enhanced sensing and applications in a Floquet time crystal sensor
M. A. Manya, Andrei Tsypilnikov, Fernando Iemini
In this work, we discuss how to determine and implement feasible optimal observables for a metrology protocol that saturates the quantum Fisher information (QFI) bound. In particul…

Kondo effect in a two-dimensional electron gas in the Persistent Spin Helix regime
T. O. Puel, M. A. Manya, G. S. Diniz +2
The Kondo effect arises from many-body interactions between localized magnetic impurities and conduction electrons, affecting electronic properties at low temperatures. In this stu…
