Phase space geometry and optimal state preparation in quantum metrology with collective spins
Manuel H. Muñoz-Arias, Ivan H. Deutsch, Pablo M. Poggi
We revisit well-known protocols in quantum metrology using collective spins and propose a unifying picture for optimal state preparation based on a semiclassical description in pha…

Floquet time crystals in driven spin systems with all-to-all -body interactions
Manuel H. Muñoz-Arias, Karthik Chinni, Pablo M. Poggi
We show the emergence of Floquet time crystal (FTC) phases in the Floquet dynamics of periodically driven -spin models, which describe a collection of spin-1/2 particles with al…
