We suggest to employ a laser-assisted tunneling scheme to establish the many-particle state of “conditional-hopping bosons”, thus realizing a gas of Abelian anyons.

Low-frequency conductivity of a nondegenerate two-dimensional electron liquid
... The question of observing the actual dynamics or electron scattering in the electron liquid has not been addressed previously. From analogy with single-electron scattering one may expect that an insight into this dynamics can be gained from the frequency dependence of xx ( ). Here, we develop an ...

Microscopic description of two dimensional dipolar quantum gases Universitat Polit` ecnica de Catalunya
... A microscopic description of the many-body properties of anisotropic homogeneous gases of bosonic dipoles in two dimensions is presented and discussed. By changing the polarization angle with respect to the plane, we study the impact of the anisotropy, present in the dipole-dipole interaction on dif ...

Generation of arbitrary Dicke states in spinor Bose±Einstein
... a spinor condensate due to the internal nonlinear atom±atom interaction [30]. In this note, we extend these results by describing a quantum control technique which allows to prepare arbitrary Dicke spin states, as well as maximally entangled states by means of properly sequencing of external couplin ...

Notes on noise
... Actually, for the case we have considered in which the noise source is classical, f (t) and f (t0 ) are real commuting variables; therefore K(t) is an even function of t and correspondingly K̃(ω) is an even function of ω. Classical noise is spectrally symmetric, and the rates for excitation and deca ...

... The micromechanical cleavage method have been also applied to other layered materials successfully, creating all sort of new 2D materials. We would like to highlight three of them: 1) Boron nitride, with an identical geometry to graphene but with two inequivalent atoms in the unit cell[3]. 2) Bismut ...

Dynamics and interference of autoionizing wave packets

The calculations are performed using R-matrix methods combined with time-dependent multichannel quantum-defect th ...
