Subsonic phase transition waves in bistable lattice models with small spinodal region
phase transitions in lattices heteroclinic travelling waves FPU-type chains kinetic relations
2012/6/14
Phase transitions waves in atomic chains with double-well potential play a fundamental role in materials science, but very little is known about their mathematical properties. In particular, the only ...
Classification of Simple Lie Algebras on a Lattice
Simple Lie Algebras Lattice Representation Theory Mathematical Physics
2011/9/1
Abstract: Let $\Lambda$ be a lattice of rank $n$. A Lie algebra on the lattice $\Lambda$ is a Lie algebra ${\cal L}=\oplus_{\lambda\in\Lambda}\,{\cal L}_{\lambda}$ such that $\dim\,{\cal L}_\lambda=1$...

Non-adiabatic transitions in a non-symmetric optical lattice
Non-adiabatic transitions non-symmetric optical lattice
2011/7/27
Abstract: We study Landau-Zener interband transitions for a non-symmetric optical lattice in the presence of an external force. We show that gain and losses of the light beam, as well as the relative ...
On non-multiaffine consistent around the cube lattice equations
Integrable lattice equations Yang-Baxter maps Consistency around the cube
2011/7/27
Abstract: We show that integrable involutive maps, due to the fact they admit three integrals in separated form, can give rise to equations which are consistent around the cube and which are not in th...

Time-Dependent Density Functional Theory Driven Lattice Gas Systems
2010/11/23
We present a new method to describe the kinetics of driven lattice gases with particle-particle
interactions beyond hard-core exclusions. The method is based on the time-dependent density
functional...
Analytic Approximations for the Extrapolation of Lattice Data

2011/1/14
We present analytic approximations of chiral SU(3) amplitudes for the extrapolation of lattice
data to the physical masses and the determination of Next-to-Next-to-Leading-Order low-energy
