Oscillating elastic defects: competition and frustration
J. Barre', A. R. Bishop, T. Lookman +1
We consider a dynamical generalization of the Eshelby problem: the strain profile due to an inclusion or "defect" in an isotropic elastic medium. We show that the higher the oscill…
Exact Elliptic Compactons in Generalized Korteweg-DeVries Equations
Fred Cooper, Avinash Khare, Avadh Saxena
We derive a general theorem relating the energy, momentum and velocity of any solitary wave solution of the generalized KdV equation which enables us to relate the amplitude, width…
Asymptotic Calculation of Discrete Nonlinear Wave Interactions
P. G. Kevrekidis, Avinash Khare, A. Saxena +2
We illustrate how to compute asymptotic interactions between discrete solitary waves of dispersive equations, using the approach proposed by Manton [Nucl. Phys. B 150, 397 (1979)].…
Statistical Mechanics of Lamé Solitons
Ioana Bena, Avinash Khare, Avadh Saxena
We study the exact statistical mechanics of Lamé solitons using a transfer matrix method. This requires a knowledge of the first forbidden band of the corresponding Schrödinger equ…
Phenomenological theory of a single domain wall in uniaxial trigonal ferroelectrics: lithium niobate and lithium tantalate
David A Scrymgeour, Venkatraman Gopalan, Amit Itagi +2
A phenomenological treatment of domain walls based on the Ginzburg-Landau-Devonshire theory is developed for uniaxial, trigonal ferroelectrics lithium niobate and lithium tantalate…
Exact solitary wave solutions for a discrete field theory in 1+1 dimensions
Fred Cooper, Avinash Khare, Bogdan Mihaila +1
We have found exact, periodic, time-dependent solitary wave solutions of a discrete field theory model. For finite lattices, depending on whether one is considering a repulsi…
Role of solvent for globular proteins in solution
A. Shiryayev, D. L. Pagan, J. D. Gunton +3
The properties of the solvent affect the behavior of the solution. We propose a model that accounts for the contribution of the solvent free energy to the free energy of globular p…
