Resistive convection in a cylindrical plasma
(1984)
It is shown that the combined effect of resistivity and thermal conductivity is responsible for the existence of marginal stationary modes in a cylindrical current-carrying plasma, under the influence of a shearless magnetic ...
Structure of liquid GeO2 from a computer simulation model
(2004)
The structural properties of liquid GeO2 were investigated using molecular dynamics simulation. A comparison of the obtained pair correlation functions, coordination number, angular distribution, and both the neutron and ...
Introduction of external field effects in the frontier molecular orbital theory of chemical reactivity
(1992)
External field effects are introduced in both charge and orbital control terms of Klopman–Salem formalism for the study of chemical reactivity in condensed phase. An analytical expression is derived for the change of the ...
Non-Hermitian robust edge states in one dimension: Anomalous localization and eigenspace condensation at exceptional points
(American Physical Society, 2018)
Capital to topological insulators, the bulk-boundary correspondence ties a topological invariant computed from the bulk (extended) states with those at the boundary, which are hence robust to disorder. Here we put forward ...
Theory of superplasticity in polycrystalline materials: Stress-induced structural instabilities of grain boundaries
(2005)
A fine mechanical analysis of a polycrystalline material subjected to large stresses must distinguish between intergranular and crystalline matter because they have different mechanical properties. Homogeneity is an illusion ...
Theory of ductility: From brittle to superplastic behavior of polycrystals
(2006)
The plastic flow of a polycrystal is calculated assuming that no sliding does occur if the in-plane components of the shear stress acting on the common grain boundary of two grains are below a threshold stress τc. Otherwise ...
Interaction of a discrete soliton with a surface mode
(2006)
We examine the formation of bound state(s) near the surface of a semi-infinite tight-binding chain, when both, a linear surface mode and a nonlinear impurity located at distance d from the surface, are present. By using ...
Nonlinear impurity in a lattice: Dispersion effects
(2003)
We examine the bound state(s) associated with a single cubic nonlinear impurity, in a one-dimensional tight-binding lattice, where hopping to first- and second-nearest neighbors is allowed. The model is solved in a closed ...
Nonlinear surface impurity in a semi-infinite lattice
(2005)
We examine the formation of bound states on a generalized nonlinear impurity located at or near the beginning (surface) of a linear, tight-binding semi-infinite lattice. Using the formalism of lattice Green functions, we ...
