Ottaviani, C., Ahufinger, V., Corbalán, R., Mompart, J.
We show that the adiabatic dynamics of a Bose-Einstein condensate (BEC) in a double well potential can be described in terms of a dark variable resulting from the combination of the population...
Doppler-free Adiabatic Self-Induced Transparency (2009)
Loiko, Yu., Serrat, C., Vilaseca, R., Ahufinger, V., Mompart, J., Corbalan, R.
We demonstrate that a Doppler broadened two-level medium can be made transparent to a laser pulse by an appropriate adiabatic variation of the laser field amplitude and its nominal detuning. This new...
Coherent Patterning of Matter Waves with Subwavelength Localization (2008)
Mompart, J., Ahufinger, V., Birkl, G.
We introduce the Subwavelength Localization via Adiabatic Passage (SLAP) technique to coherently achieve state-selective patterning and addressing of matter waves. The SLAP technique consists in...
Double barrier potentials for matter-wave gap solitons (2008)
Ahufinger, V., Malomed, B. A., Birkl, G., Corbalan, R., Sanpera, A.
We investigate collisions of solitons of the gap type, supported by a lattice potential in repulsive Bose-Einstein condensates, with an effective double-barrier potential that resembles a Fabry-Perot...
Quantum switches and quantum memories for matter-wave lattice solitons (2006)
Ahufinger, V., Mebrahtu, A., Corbalan, R., Sanpera, A.
We study the possibility of implementing a quantum switch and a quantum memory for matter wave lattice solitons by making them interact with "effective" potentials (barrier/well) corresponding to...
Disordered ultracold atomic gases in optical lattices: A case study of Fermi-Bose mixtures (2006)
Ahufinger, V., Sanchez-Palencia, L., Kantian, A., Sanpera, A., Lewenstein, M.
We present a review of properties of ultracold atomic Fermi-Bose mixtures in inhomogeneous and random optical lattices. In the strong interacting limit and at very low temperatures, fermions form,...

Trapped ion chain as a neural network (2005)
Pons, M., Ahufinger, V., Wunderlich, C., Sanpera, A., Lewenstein, M.
We demonstrate the possibility of realizing a neural network in a chain of trapped ions with induced long range interactions. Such models permit to store information distributed over the whole...

Lattice solitons in quasicondensates (2004)
We analyze finite temperature effects in the generation of bright solitons in condensates in optical lattices. We show that even in the presence of strong phase fluctuations solitonic structures with...
Ahufinger, V., Sanpera, A., Pedri, P., Santos, L., Lewenstein, M.
We analyze the generation and mobility of discrete solitons in Bose-Einstein condensates confined in an optical lattice under realistic experimental conditions. We discuss first the creation of 1D...
Lasing without population inversion: towards continuous wave X-ray laser emission (2000)
