Numerical simulations of nonlinear modes in mica: past, present and future
J. Bajars, J. C. Eilbeck, B. Leimkuhler
We review research on the role of nonlinear coherent phenomena (e.g breathers and kinks) in the formation linear decorations in mica crystal. The work is based on a new model for t…
Quantization of β-Fermi-Pasta-Ulam Lattice with Nearest and Next-nearest Neighbour Interactions
Aniruddha Kibey, Rupali Sonone, Bishwajyoti Dey +1
We quantize the β-Fermi-Pasta-Ulam (FPU) model with nearest and next-nearest neighbour interactions using a number conserving approximation and a numerical exact diagonalization me…
Quantum breathers in an attractive fermionic Hubbard model
J. C. Eilbeck, F. Palmero
In one-dimensional translationally invariant anharmonic lattices, an extended Bloch state with two or more strongly correlated particles is usually called a quantum breather. Here…
Influence of moving breathers on vacancies migration
J. Cuevas, C. Katerji, J. F. R. Archilla +2
A vacancy defect is described by a Frenkel--Kontorova model with a discommensuration. This vacancy can migrate when interacts with a moving breather. We establish that the width of…
The Discrete Nonlinear Schrödinger equation - 20 Years on
J. Chris Eilbeck, Magnus Johansson
We review work on the Discrete Nonlinear Schrödinger (DNLS) equation over the last two decades.
