Capillary-induced interactions between colloids at an interface
Alvaro Dominguez, Martin Oettel, Siegfried Dietrich
Within a general framework we study the effective, deformation-induced interaction between two colloids trapped at a fluid interface. As an application, we consider the interface d…
Effective Lagrangian Approach to pion photoproduction from the nucleon
C. Fernandez-Ramirez, E. Moya de Guerra, J. M. Udias
We present a pion photoproduction model on the free nucleon based on an Effective Lagrangian Approach (ELA) which includes the nucleon resonances (, N(1440), N(1520), N(15…
Continuous unitary transformations in two-level boson systems
S. Dusuel, J. Vidal, J. M. Arias +2
Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with $O…
Three-body continuum discretization in a basis of transformed harmonic oscillator states
M. Rodriguez-Gallardo, J. M. Arias, J. Gomez-Camacho +3
The inclusion of the continuum in the study of weakly-bound three-body systems is discussed. A transformed harmonic oscillator basis is introduced to provide an appropriate discret…
A flatness property for filtered D-modules
F. J. Castro-Jimenez, M. Granger
Let M be a coherent module over the ring D of linear differential operators on an analytic manifold X and let us consider k germs of transverse hypersurfaces at a point x in X. The…
Aharonov-Bohm effect for an exciton in a finite width nano-ring
F. Palmero, J. Dorignac, J. C. Eilbeck +1
We study the Aharonov-Bohm effect for an exciton on a nano-ring using a 2D attractive fermionic Hubbard model. We extend previous results obtained for a 1D ring in which only azimu…
