n-body dynamics of stabilized vector solitons
Gaspar D. Montesinos, Maria I. Rodas-Verde, Victor M. Perez-Garcia +1
In this work we study the interactions between stabilized Townes solitons. By means of effective Lagrangian methods, we have found that the interactions between these solitons are…
Whole Earth Telescope observations of BPM 37093: a seismological test of crystallization theory in white dwarfs
A. Kanaan, A. Nitta, D. E. Winget +3
BPM 37093 is the only hydrogen-atmosphere white dwarf currently known which has sufficient mass (~ 1.1 M_sun) to theoretically crystallize while still inside the ZZ Ceti instabilit…
Categorical non abelian cohomology, and the Schreier theory of groupoids
V. Blanco, M. Bullejos, E. Faro
By regarding the classical non abelian cohomology of groups from a 2-dimensional categorical viewpoint, we are led to a non abelian cohomology of groupoids which continues to satis…
Postnikov Invariants of Crossed Complexes
M. Bullejos, E. Faro, M. A. García-Muñoz
We determine the Postnikov Tower and Postnikov Invariants of a Crossed Complex in a purely algebraic way. Using the fact that Crossed Complexes are homotopy types for filtered spac…
Stable propagation of pulsed beams in Kerr focusing media with modulated dispersion
Maria I. Rodas-Verde, Gaspar D. Montesinos, Humberto Michinel +1
We propose the modulation of dispersion to prevent collapse of planar pulsed beams which propagate in Kerr-type self-focusing optical media. As a result, we find a new type of two-…
Controllable matter-wave switchers with vector Bose-Einstein solitons
Judit Babarro, María J. Paz-Alonso, Humberto Michinel +2
We show the possibility of producing matter-wave switching devices by using Manakov interactions between matter wave solitons in two-species Bose-Einstein Condensates (BEC). Our re…
