Abstract: Abstract The Hubbard model in a bipartite face-centered cubic (fcc) lattice is studied in the tight-binding limit and using the mean-field approximation. This bipartite lattice can be obtained from the traditional fcc lattice by considering… read more here.

Abstract: Delocalized nonlinear vibrational modes (DNVMs) supported in crystal lattices are exact solutions to the equations of motion of particles that are determined by the symmetry of the lattices. DNVMs exist for any vibration amplitudes and for… read more here.
