Creating collective many-body states with highly excited atoms (2009)
Olmos, B., González-Férez, R., Lesanovsky, I.
We study the collective excitation of a gas of highly excited atoms confined to a large spacing ring lattice, where the ground and the excited states are coupled resonantly via a laser field. Our...
Fermionic collective excitations in a lattice gas of Rydberg atoms (2009)
Olmos, B., González-Férez, R., Lesanovsky, I.
We investigate the many-body quantum states of a laser-driven gas of Rydberg atoms confined to a large spacing ring lattice. If the laser driving is much stronger than the van-der-Waals interaction...
Localization in excitation number space of a strongly interacting Rydberg gas (2009)
Olmos, B., Müller, M., Lesanovsky, I.
When Rydberg states are excited in a dense atomic gas the mean number of excited atoms reaches a stationary value after an initial transient period. We shed light on the origin of this steady state...
Collective Rydberg excitations of an atomic gas confined in a ring lattice (2008)
Olmos, B., González-Férez, R., Lesanovsky, I.
We study the excitation dynamics of Rydberg atoms in a one-dimensional lattice with periodic boundary conditions where the atomic Rydberg states are resonantly excited from the electronic ground...
Parameter-based Fisher's information of orthogonal polynomials (2006)
Dehesa, J. S., Olmos, B., Yanez, R. J.
The Fisher information of the classical orthogonal polynomials with respect to a parameter is introduced, its interest justified and its explicit expression for the Jacobi, Laguerre, Gegenbauer and...
