Geometry and quantum brachistochrone analysis of multiple entangled spin-1/2 particles under all-range Ising interaction
B. Amghar, M. Yachi, M. Amghar +3
We present a unified geometric and dynamical framework for a physical system consisting of spin- particles with all-range Ising interaction. Using the Fubini-Study formali…
