  • Quantum switches and quantum memories for matter-wave lattice solitons 
    Ahufinger, V.; Mebrahtu, A.; Corbalan, R.; Sanpera, A. (Bristol : IOP Publishing Ltd., 2007)
    We study the possibility of implementing a quantum switch and a quantum memory using matter-wave lattice solitons and making them interact with 'effective' potentials (barrier/well) corresponding to defects of the optical ...
  • Transmission amplitudes from Bethe ansatz equations 
    Doikou, Anastasia; Karaiskos, Nikos (New York, NY : Springer International Publishing, 2013)
    We consider the Heisenberg spin chain in the presence of integrable spin defects. Using the Bethe ansatz methodology, we extract the associated transmission amplitudes, that describe the interaction between the particle-like ...
