Double barrier potentials for matter-wave gap solitons
V. Ahufinger, B. A. Malomed, G. Birkl +2
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 rese…
Quantum switches and quantum memories for matter-wave lattice solitons
V. Ahufinger, A. Mebrahtu, R. Corbalan +1
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) c…
Trapped Ion Chain as a Neural Network: Error Resistant Quantum Computation
Marisa Pons, Veronica Ahufinger, Christof Wunderlich +5
We demonstrate the possibility of realizing a neural network in a chain of trapped ions with induced long range interactions. Such models permit one to store information distribute…
Ultracold atomic gases in optical lattices: mimicking condensed matter physics and beyond
Maciej Lewenstein, Anna Sanpera, Veronica Ahufinger +3
We review recent developments in the physics of ultracold atomic and molecular gases in optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard m…
Strongly correlated Fermi-Bose mixtures in disordered optical lattices
L. Sanchez-Palencia, V. Ahufinger, A. Kantian +3
We investigate theoretically the low-temperature physics of a two-component ultracold mixture of bosons and fermions in disordered optical lattices. We focus on the strongly correl…
Disordered complex systems using cold gases and trapped ions
Aditi Sen De, Ujjwal Sen, Maciej Lewenstein +3
We report our research on disordered complex systems using cold gases and trapped ions, and address the possibility of using complex systems for quantum information processing. Two…
