Author(s): I. A. Ivanov and A. S. Kheifets We perform a time-delay analysis of the strong field ionization of atomic hydrogen in the tunneling regime. We obtain values for the time delay by solving the time-dependent Schrödinger equation, and use these values as parameters to define the corresponding classical trajectories. We demonstrate th… [Phys. Rev. [...]

Author(s): Mathias Boström, Bo E. Sernelius, Iver Brevik, and Barry W. Ninham Casimir forces between surfaces immersed in bromobenzene have recently been measured by Munday et al. [ Nature (London) 454 07610 (2009)]. Attractive Casimir forces were found between gold surfaces. The forces were repulsive between gold and silica surfaces. We show the repulsion is [...]

Author(s): G. A. T. Pender, P. F. Barker, Florian Marquardt, J. Millen, and T. S. Monteiro Optomechanical cooling of levitated dielectric particles represents a promising new approach in the quest to cool small mechanical resonators toward their quantum ground state. We investigate two-mode cooling of levitated nanospheres in a self-trapping regime. We identify a structure [...]

Author(s): Daisuke Yamamoto, Ippei Danshita, and Carlos A. R. Sá de Melo We study phase transitions and hysteresis in a system of dipolar bosons loaded into triangular optical lattices at zero temperature. We find that the quantum melting transition from supersolid to superfluid phase is first order, in contrast with the previous report. We also [...]

Author(s): Francesco Ciccarello and Vittorio Giovannetti We show that two qubits, initially in a fully classical state, can develop significant quantum correlations as measured by the quantum discord (QD) under the action of a local memoryless noise (specifically we consider the case of a Markovian amplitude-damping channel). This is analytically proven a… [Phys. Rev. A [...]
