Non-relativistic classical mechanics for spinning particles
G. Salesi
We study the classical dynamics of non-relativistic particles endowed with spin. Non-vanishing Zitterbewegung terms appear in the equation of motion also in the small momentum limi…
Resonant and non-resonant Tunneling through a double barrier
Vladislav S. Olkhovsky, Erasmo Recami, A. K. Zaichenko
An explicit expression is obtained for the phase-time corresponding to tunneling of a (non-relativistic) particle through two rectangular barriers, both in the case of resonant and…
Entanglement Across a Transition to Quantum Chaos
Carlos Mejia-Monasterio, Giuliano Benenti, Gabriel G. Carlo +1
We study the relation between entanglement and quantum chaos in one- and two-dimensional spin-1/2 lattice models, which exhibit mixing of the noninteracting eigenfunctions and tran…
Uniform semiclassical approach to fidelity decay in the deep Lyapunov regime
Wen-ge Wang, G. Casati, Baowen Li +1
We use the uniform semiclassical approximation in order to derive the fidelity decay in the regime of large perturbations. Numerical computations are presented which agree with our…
A complete characterization of phase space measurements
C. Carmeli, G. Cassinelli, E. DeVito +2
We characterize all the phase space measurements for a non-relativistic particle.
Robust generation of entanglement in Bose-Einstein condensates by collective atomic recoil
Mary M. Cola, Matteo G. A. Paris, Nicola Piovella
We address the dynamics induced by collective atomic recoil in a Bose-Einstein condensate in presence of radiation losses and atomic decoherence. In particular, we focus on the lin…
Quantum computing and information extraction for a dynamical quantum system
Giuliano Benenti, Giulio Casati, Simone Montangero
We discuss the simulation of a complex dynamical system, the so-called quantum sawtooth map model, on a quantum computer. We show that a quantum computer can be used to efficiently…
About distillability of depolarized states
Andrea R. Rossi, Matteo G. A. Paris
Reduction criteria for distillability is applied to general depolarized states and an explicit condition is found in terms of a characteristic polynomial of the density matrix. 3 $…
