Ferroelastic Dynamics and Strain Compatibility
T. Lookman, S. R. Shenoy, K. O. Rasmussen +2
We derive underdamped evolution equations for the order-parameter (OP) strains of a ferroelastic material undergoing a structural transition, using Lagrangian variations with Rayle…
Atomic scale lattice distortions and domain wall profiles
K. H. Ahn, T. Lookman, A. Saxena +1
We present an atomic scale theory of lattice distortions using strain related variables and their constraint equations. Our approach connects constrained {\it atomic length} scale…
Thermodynamics of a Higher Order Phase Transition: Scaling Exponents and Scaling Laws
P. Kumar, A. Saxena
The well known scaling laws relating critical exponents in a second order phase transition have been generalized to the case of an arbitrarily higher order phase transition. In a h…
Scattering of a solitary pulse on a local defect or breather
Panayotis G. Kevrekidis, Boris A. Malomed, H. E. Nistazakis +3
A model is introduced to describe guided propagation of a linear or nonlinear pulse which encounters a localized nonlinear defect, that may be either static or breather-like one (t…
