On the generalized eigenvalue method for energies and matrix elements in lattice field theory
(INT SCHOOL ADVANCED STUDIES, 2009)
We discuss the generalized eigenvalue problem for computing energies and matrix elements in lattice gauge theory, including effective theories such as HQET. It is analyzed how the extracted effective energies and matrix ...
Analysis of Lattice Size, Energy Density and Denaturation for a One-Dimensional DNA Model
(2012)
There are several mechanical models to describe the DNA phenomenology. In this work the DNA denaturation is stu- died under thermodynamical and dynamical point of view using the well known Peyrard-Bishop model. The ...
Phase-separated symmetry-breaking vortex-lattice in a binary Bose-Einstein condensate
(2020-01-01)
We study spontaneous-symmetry-breaking circularly-asymmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with repulsive ...
Study of surface free energy on a lattice-gas model applied to Liquid bridge
(Águas de Lindóia, 2013-05)
The pulmonary crackling and the formation of liquid bridges are problems that for centuries have been attracting the attention of scientists. In order to study these phenomena, it was developed a canonical cubic ...
Natural vibrations and buckling of a spatial lattice structure using a continuous model derived from an energy approach
(Korean Society of Steel Construction, 2017-06)
Lattice structures composed by parallel members named chords (or legs for vertical configurations) and connected by diagonals are very common among steel constructions in Civil and Mechanical Engineering and in particular, ...
Toda lattice field theories, discrete W algebras, Toda lattice hierarchies and quantum groups
(1996-10-31)
In analogy with the Liouville case we study the sl3 Toda theory on the lattice and define the relevant quadratic algebra and out of it we recover the discrete W3 algebra. We define an integrable system with respect to the ...

Electron–lattice coupling after high-energy deposition in aluminum
(Elsevier, 2015-07)
This paper presents an analysis of the parameters of highly-excited electron subsystem of aluminum, appearing e.g. after swift heavy ion impact or laser pulse irradiation. For elevated electron temperatures, the electron ...
On the Optimality of Finite Constellations from Algebraic Lattices
(2001-04-01)
A construction technique of finite point constellations in n-dimensional spaces from ideals in rings of algebraic integers is described. An algorithm is presented to find constellations with minimum average energy from a ...
