Non-Markovian Dynamics of Spin Squeezing

, 2013
We evaluate the spin squeezing dynamics of N independent spin-1/2 particles with exchange symmetry. Each spin interacts with its own reservoir, and the reservoirs are independently and identical.

Robertson Intelligent States [PDF]

, 1997
Diagonalization of uncertainty matrix and minimization of Robertson inequality for n observables are considered. It is proved that for even n this relation is minimized in states which are eigenstates of n/2 independent complex linear combinations of the

Influence of intrinsic decoherence on nonclassical properties of the output of a Bose-Einstein condensate

, 2005
We investigate nonclassical properties of the output of a Bose-Einstein condensate in Milburn's model of intrinsic decoherence. It is shown that the squeezing property of the atom laser is suppressed due to decoherence. Nevertheless, if some very special

Standard super-activation for Gaussian channels requires squeezing [PDF]

, 2013
The quantum capacity of bosonic Gaussian quantum channels can be non-additive in a particularly striking way: a pair of such optical-fiber type channels can individually have zero quantum capacity but super-activate each other such that the combined ...

Reflections on generating (disjunctive) cuts

EURO Journal on Computational Optimization, 2013
We consider the problem of constructing generic supporting hyperplanes to be used within a (branch and) bound-and-cut algorithm. We review some of the properties that these hyperplanes should enjoy.

Spin-Nematic Squeezed Vacuum in a Quantum Gas

, 2012
Using squeezed states it is possible to surpass the standard quantum limit of measurement uncertainty by reducing the measurement uncertainty of one property at the expense of another complementary property.

Prediction of the friction coefficient of filled rubber sliding on dry and wet surfaces with self-affine large roughness

Mechanical Engineering Journal, 2016
The friction of filled rubber on a rough surface is mainly determined by the rubber viscoelasticity and the surface property of multiple-scale asperities that can be represented by the power spectral density of the surface profile (i.e., power spectrum ...

Theory of quantum fluctuations of optical dissipative structures and its application to the squeezing properties of bright cavity solitons [PDF]

, 2007
We present a method for the study of quantum fluctuations of dissipative structures forming in nonlinear optical cavities, which we illustrate in the case of a degenerate, type I optical parametric oscillator.

On the uniform squeezing property and the squeezing function

, 2013
We describe the boundary behaviors of the squeezing functions for all bounded convex domains in $\mathbb{C}^n$ and bounded domains with a $C^2$ strongly convex boundary point.

Generalized $su(2)$ coherent states for the Landau levels and their nonclassical properties

, 2013
Following the lines of the recent papers [J. Phys. A: Math. Theor. 44, 495201 (2012); Eur. Phys. J. D 67, 179 (2013)], we construct here a new class of generalized coherent states related to the Landau levels, which can be used as the finite Fock ...
