The entropy of coupled map lattices with respect to the group
of space-time translations is considered. We use the notion of generalized
Lyapunov spectra ([11]) to prove the analogue of Ruelle inequ...
INEQUALITIES FOR THE H-AND FLAG H-VECTORS OF GEOMETRIC LATTICES
H-AND FLAG H-VECTORS GEOMETRIC LATTICES
2015/8/25
We prove that the order complex of a geometric lattice has a convex ear decomposition. As a consequence, if ∆(L) is the order complex of a rank (r +1) geometric lattice L, then the for all i ≤ r...
Unusual States of Vortex Matter in Mixtures of Bose-Einstein Condensates on Rotating Optical Lattices
Superfluid parameter space vortex lattice parameters the mixture of condensed matter optical lattice
2014/12/19
In a single-component superfluid under rotation a broken symmetry in the order parameter space results in a broken translational symmetry in real space: a vortex lattice. If translational symmetry is ...

Rotation statistical mechanics model of superfluid vortex lattice vortex lattice
2014/12/19
We study the evolution of rotational response of a statistical mechanical model of two-component superfluid with a nondissipative drag interaction as the system undergoes a transition into a paired su...
Discrete Parity-Time Symmetric Nonlinear Schrodinger Lattices
Lattices Parity-time Symmetry Schrodinger
2014/12/8
In this thesis we summarize the classical cases of one-dimensional oligomers and two dimensional plaquettes, respecting the parity-time (PT ) symmetry. We examine different types of solutions of such ...
Elimination of transverse instability in stripe solitons by one-dimensional lattices
Elimination of transverse stripe solitons one-dimensional lattices Optics
2012/5/28
We demonstrate theoretically and experimentally that the transverse instability of coherent soliton stripes can be greatly suppressed or totally eliminated when the soliton stripes propagate in a one-...
This survey is a brief introduction to the theory of hyperbolic buildings and their lattices, with a focus on recent results.

$Top(X)$ within $\px$ lattices meet topology
2012/2/29
For a non-empty set $X$, the collection $Top(X)$ of all topologies on $X$ sits inside the Boolean lattice $\PP(\PP(X))$ (when ordered by set-theoretic inclusion) which in turn can be naturally identif...
Spectra and ground states of one- and two-dimensional laser-driven lattices of ultracold Rydberg atoms
Spectra ground states one- and two-dimensional laser-driven lattices ultracold Rydberg atoms
2012/2/28
We investigate static properties of laser-driven, ultracold Rydberg atoms confined to one- and two-dimensional uniform lattices in the limit of vanishing laser coupling. The spectral structure of squa...

2011/9/23
Abstract: We present a general theory for studying the difference analogues of special functions of hypergeometric type on the linear-type lattices, i.e., the solutions of the second order linear diff...

2011/10/9
Abstract: We study a superfluid in a rotating anharmonic trap and explicate a rigorous proof of a transition from a vortex lattice to a giant vortex state as the rotation is increased beyond a limitin...

Abstract: We numerically investigate the heat conduction behavior of one-dimensional momentum-conserved lattice systems with {\it asymmetric} interactions. The heat conductivity is measured by couplin...

2011/9/13
Abstract: We deal with the question of whether or not the p-convexified couple (X_0^{(p)},X_1^{(p)}) is a Calderon couple under the assumption that (X_0,X_1) is a Calderon couple of Banach lattices on...

Abstract: We show that the Gross-Pitaevskii equation with cubic nonlinearity, as a model to describe the one dimensional Bose-Einstein condensates loaded into a harmonically confined optical lattice, ...
