Abstract: We propose a model-building framework unifying those continuum models of condensed matter accounting for second-neighbor interactions. A notion of material isomorphism justifies restrictions that we impose to changes in observers on the material manifold. In… read more here.

Abstract: Abstract The diffusion of particles adsorbed on a homogeneous one-dimensional sawtooth lattice with the nearest neighbor and the next nearest neighbor interactions between the particles is investigated using a theoretical approach and the kinetic Monte… read more here.

DOI: 10.1103/physreva.95.063605
Abstract: We study spinless fermions with repulsive nearest-neighbor interactions perturbed by an impurity particle or a local potential quench. Using the numerical time-evolving block decimation method and a simplified analytic model, we show that the perturbations… read more here.
