Delay Times for Symmetrized and Antisymmetrized Quantum Tunneling Configurations
Alex E. Bernardini
The transit times are obtained for a symmetrized (two identical bosons) and an antisymmetrized (two identical fermions) quantum colliding configuration. Considering two identical p…
Symmetry breaking effects upon bipartite and multipartite entanglement in the XY model
Thiago R. de Oliveira, Gustavo Rigolin, Marcos C. de Oliveira +1
We analyze the bipartite and multipartite entanglement for the ground state of the one-dimensional XY model in a transverse magnetic field in the thermodynamical limit. We explicit…
Driving-dependent damping of Rabi oscillations in two-level semiconductor systems
D. Mogilevtsev, A. P. Nisovtsev, S. Kilin +3
We propose a mechanism to explain the nature of the damping of Rabi oscillations with increasing driving-pulse area in localized semiconductor systems, and have suggested a general…
Relativistic tunneling and accelerated transmission
Alex E. Bernardini
We obtain the solutions for the tunneling zone of a one-dimensional electrostatic potential in the relativistic (Dirac to Klein-Gordon) wave equation regime when the incoming wave…
The Exact Correspondence between Phase Times and Dwell Times in a Symmetrical Quantum Tunneling Configuration
Alex E. Bernardini
The general and explicit relation between the phase time and the dwell time for quantum tunneling or scattering is investigated. Considering a symmetrical collision of two identica…
Cluster-type entangled coherent states
P. P. Munhoz, F. L. Semião, A. Vidiella-Barranco +1
We present the cluster-type entangled coherent states (CTECS) and discuss their properties. A cavity QED generation scheme using suitable choices of atom-cavity interactions, obtai…
Controlling Phase Space Caustics in the Semiclassical Coherent State Propagator
A. D. Ribeiro, M. A. M. de Aguiar
The semiclassical formula for the quantum propagator in the coherent state representation is not free from the problem of caus…
Generalized Quantum Telecloning
Goren Gordon, Gustavo Rigolin
We present a generalized telecloning (GTC) protocol where the quantum channel is non-optimally entangled and we study how the fidelity of the telecloned states depends on the entan…
Minimal set of local measurements and classical communication for two-mode Gaussian state entanglement quantification
Luis F. Haruna, Marcos C. de Oliveira, Gustavo Rigolin
We develop the minimal requirements for the complete entanglement quantification of an arbitrary two-mode bipartite Gaussian state via local measurements and a classical communicat…
Limitations on the principle of stationary phase when it is applied to tunneling analysis
Alex E. Bernardini
Using a recently developed procedure - multiple wave packet decomposition - here we study the phase time formulation for tunneling/reflecting particles colliding with a potential b…
Physical properties of the Schur complement of local covariance matrices
Luis F. Haruna, Marcos C. de Oliveira
General properties of global covariance matrices representing bipartite Gaussian states can be decomposed into properties of local covariance matrices and their Schur complements.…
