Rotor/spin-wave theory for quantum spin models with U(1) symmetry
Tommaso Roscilde, Tommaso Comparin, Fabio Mezzacapo
The static and dynamics properties of finite-size lattice quantum spin models which spontaneously break a continuous symmetry in the thermodynamic limit are of central impor…
Scalable spin squeezing in a dipolar Rydberg atom array
Guillaume Bornet, Gabriel Emperauger, Cheng Chen +11
The standard quantum limit bounds the precision of measurements that can be achieved by ensembles of uncorrelated particles. Fundamentally, this limit arises from the non-commuting…
Entangling dynamics from effective rotor/spin-wave separation in U(1)-symmetric quantum spin models
Tommaso Roscilde, Tommaso Comparin, Fabio Mezzacapo
The non-equilibrium dynamics of quantum spin models is a most challenging topic, due to the exponentiality of Hilbert space; and it is central to the understanding of the many-body…
