Continuum description of profile scaling in nanostructure decay
Continuum description profile scaling nanostructure decay
2015/10/16
The relaxation of axisymmetric crystal surfaces with a single facet below the roughening transition is studied via a continuum approach that accounts for step energy g1 and step-step interaction energ...
Classical phases and quantum angles in the description of interfering Bose-Einstein condensates
Condensate random variables measurements
2014/12/19
The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can be understood eithe...
The Shockley model description of the surface states in topological insulators
Shockley model description surface states topological insulators
2012/2/27
We show that the surface states in topological insulators can be understood based on a well-known Shockley model, a one-dimensional tight-binding model with two atoms per elementary cell, connected vi...
Transport-theoretical Description of Nuclear Reactions
Transport theory Hadron-induced reactions Heavy-ion collisions
2011/7/21
In this review we first outline the basics of transport theory and its recent generalization to off-shell transport. We then present in some detail the main ingredients of any transport method using i...
Relativistic Description of Finite Nuclei Based on Realistic $NN$ Interactions
$NN$ Interactions
2011/7/20
A set of relativistic mean field models is constructed including the Hartree and Hartree-Fock approximation accounting for the exchange of isoscalar and isovector mesons as well as the pion.
Any Classical Description of Nature Requires Classical Electromagnetic Zero-Point Radiation
Classical Description Nature Electromagnetic Zero-Point Radiation
2011/8/5
Abstract: Any attempt to describe nature within classical physics requires the presence of Lorentz-invariant classical electromagnetic zero-point radiation so as to account for the Casimir forces betw...
Minimal Number of Discrete Velocities for a Flow Description
Minimal Number Discrete Velocities Flow Description
2011/8/17
Abstract: It seems intuitively correct to describe fluid flows by using fictitious particles hopping on homogeneously separated nodes with a given finite set of discrete velocities, however, it is not...

Theoretical description of two ultracold atoms in finite 3D optical lattices using realistic interatomic interaction potentials
Theoretical description two ultracold atoms finite 3D optical lattices realistic interatomic
2011/8/4
Abstract: A theoretical approach is described for an exact numerical treatment of a pair of ultracold atoms interacting via a central potential that are trapped in a finite three-dimensional optical l...
Semiclassical Description of Relativistic Spin without use of Grassmann variables and the Dirac equation
Relativistic Spin Grassmann variables Dirac equation
2011/9/29
Abstract: We propose the relativistic particle model without Grassmann variables which, being canonically quantized, leads to the Dirac equation. Both $\Gamma$\,-matrices and the relativistic spin-ten...
Statefinder Description in Generalized Holographic and Ricci Dark Energy Models
Statefinder Ricci Dark Energy Models
2011/9/7
We have considered the generalized holographic and generalized Ricci dark energy models for acceleration of the universe. If the universe filled with only GHDE/GRDE the corresponding decel-eration par...

Field theory description of neutrino oscillations
Field theory description neutrino oscillations
2010/12/27
We review various field theory approaches to the description of neutrino oscillations in vacuum and external fields. First we discuss a relativistic quantum mechanics based approach which involves th...
Based on the earlier work [S.-S. Lee, Nucl. Rev. B 832, 567 (2010)], we derive a holographic dual for the D-dimensional U(N) lattice gauge theory from a first principle construction. The resulting the...
Topological BF field theory description of topological insulators
Topological BF field theory description topological insulators
2010/12/27
Topological phases of matter are described universally by topological field theories in the same way that symmetry-breaking phases of matter are described by Landau-Ginzburg field theories. We propos...
