Scattering of atomic dark-bright solitons from narrow impurities
(2013)
In this work, we examine the collision of an atomic dark-bright soliton, in a two-component Bose-Einstein condensate, with a Gaussian barrier or well. Our study has both an experimental component and a theoretical/computational ...

Spiral waves solutions in reaction-diffusion equations with symmetries. Analysis through specific models
(IOP Science, 1997)
Symmetries of nonlinear reaction-diffusion equations determine the existence of regular rotating spiral waves. They are only a consequence of kinetics processes and molecular diffusion. We prove the existence of these waves ...

Moving breathers in a DNA model with competing short and long range dispersive interactions
(2002)
Moving breathers is a means of transmitting information in DNA. We study the existence and properties of moving breathers in a DNA model with short range interaction, due to the stacking of the base pairs, and long range ...

Dynamics of the Davydov-Scott monomer in a thermal bath: comparison of the full quantum and semiclassical approaches
(2007)
The quantum state diffusion equation is applied to the problem of energy transfer in proteins. Lindblad operators, capable of coupling the full quantum Davydov-Scott monomer to a thermal bath, are derived. Numerical ...
