Entanglement is a very fundamental and amazing feature of quantum theory. It measures non-classical non-local correlations between different parts of a quantum system. If the quantum system is in a highly entangled state, measuring an observable on a part of the system can strongly and instantaneously affect the state of another part of the system, […]
L. Šamaj 1, 2, E. Trizac 2 Physical Review E 84 (2011) 041401 We present a new analytical approach to the strong electrostatic coupling regime (SC), that can be achieved equivalently at low temperatures, high charges, low dielectric permittivity etc. Two geometries are analyzed in detail: one charged wall first, and then, two parallel walls at small distances, that can

Ehsan Noruzifar 1, Thorsten Emig 2, Roya Zandi 1 Physical Review A 84 (2011) 042501 We calculate the Casimir interaction between two parallel wires and between a wire and a metall plate. The dielectric properties of the objects are described by the plasma, Drude and perfect metal models. We find that at asymptotically large separation interactions involving plasma wires and/or plates

Zyss 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 83 (2011) 036208 Dielectric resonators are open systems particularly interesting due to their wide range of applications in optics and photonics. In a recent paper [PRE, vol. 78, 056202 (2008)] the trace formula for both the smooth and
J. Levinsen 1, 2, N. R. Cooper 1, 2, G. V. Shlyapnikov 1, 3 Physical Review A 84 (2011) 013603 We discuss the topological p_x+ip_y superfluid phase in a 2D gas of single-component fermionic polar molecules dressed by a circularly polarized microwave field. This phase emerges because the molecules may interact with each other via a potential V_0(r) that has an attractive dipole-dipole 1/r^3

Shlyapnikov 1, 3 Physical Review A: Atomic, Molecular and Optical Physics 83 (2011) 033604 We have found an exact analytical solution of the Bogoliubov-de Gennes equations for the Tkachenko modes of the vortex lattice in the lowest Landau level (LLL) in the thermodynamic limit at any momenta and calculated their damping rates. At finite

Lerner 4 Physical Review B 84 (2011) 054204 We study Johnson-Nyquist noise in macroscopically inhomogeneous disordered metals and give a microscopic derivation of the correlation function of the scalar electric potentials in real space. Starting from the interacting Hamiltonian for electrons in a metal and the random phase approximation,

P. Delplace 1, D. Ullmo 2, G. Montambaux 3 Physical Review B 84 (2011) 195452 We develop a method to predict the existence of edge states in graphene ribbons for a large class of boundaries. This approach is based on the bulk-edge correspondence between the quantized value of the Zak phase Z(k), which is a Berry phase across an appropriately chosen

Majumdar 1, Alberto Rosso 1 Journal of Physics A: Mathematical and Theoretical 44, 41 (2011) 415001 We compute exactly the mean perimeter and the mean area of the convex hull of a random acceleration process of duration T in two dimensions. We use an exact mapping that relates, via Cauchy’s formulae, the computation of the perimeter
