Beyond the Jaynes-Cummings model: circuit QED in the ultrastrong coupling regime (2010)
Niemczyk, T., Deppe, F., Huebl, H., Menzel, E. P., Hocke, F., Schwarz, M. J., ...
In cavity quantum electrodynamics (QED), light-matter interaction is probed at its most fundamental level, where individual atoms are coupled to single photons stored in three-dimensional cavities....
Ab Initio Molecular Dynamics on the Electronic Boltzmann Equilibrium Distribution (2010)
Alonso, J. L., Castro, A., Echenique, P., Polo, V., Rubio, A., Zueco, D.
We prove that for a combined system of classical and quantum particles, it is possible to write a dynamics for the classical particles that incorporates in a natural way the Boltzmann equilibrium...
Nikitin, A. Yu., Zueco, D., Garcia-Vidal, F. J., Martin-Moreno, L.
The non-resonant electromagnetic transmission of a normal-incident plane wave through a single hole in a perfect conductor metal slab of finite width is studied. The cases of rectangular and circular...
Nonlinear response of single-molecule magnets : Field-tuned quantum-to-classical crossovers. (2007)
López-Ruiz, R., Luis, F, Millán, A., Rillo, C., Zueco, D., García-Palacios, J. L.
Quantum nanomagnets can show a field dependence of the relaxation time very different from their classical counterparts, due to resonant tunneling via excited states (near the anisotropy barrier...
As already known for nonrelativistic spinless particles, Bopp operators give an elegant and simple way to compute the dynamics of quasiprobability distributions in the phase space formulation of...

Non-linear response of single-molecule magnets: field-tuned quantum-to-classical crossovers (2006)
Lopez-Ruiz, R., Luis, F., Millan, A., Rillo, C., Zueco, D., Garcia-Palacios, J. L.
Quantum nanomagnets can show a field dependence of the relaxation time very different from their classical counterparts, due to resonant tunneling via excited states (near the anisotropy barrier...
Garcia-Palacios, J. L., Zueco, D.
We implement continued-fraction techniques to solve exactly quantum master equations for a spin with arbitrary S coupled to a (bosonic) thermal bath. The full spin density matrix is obtained, so that...
Longitudinal relaxation and thermoactivation of quantum superparamagnets. (2006)
Zueco, D., Garcia-palacios, J.L.
The relaxation mechanisms of a quantum nanomagnet are discussed in the frame of linear response theory. We use a spin Hamiltonian with a uniaxial potential barrier plus a Zeeman term. The spin,...
Longitudinal relaxation and thermoactivation of quantum superparamagnets (2005)
Zueco, D., Garcia-Palacios, J. L.
The relaxation mechanisms of a quantum nanomagnet are discussed in the frame of linear response theory. We use a spin Hamiltonian with a uniaxial potential barrier plus a Zeeman term. The spin,...
Quantum Ratchets at High Temperatures (2004)
Zueco, D., Garcia-Palacios, J. L.
Using the continued-fraction method we solve the Caldeira-Leggett master equation in the phase-space (Wigner) representation to study Quantum ratchets. Broken spatial symmetry, irreversibility and...
Mode-Locking of mobile discrete breathers (2004)
Zueco, D., Martinez, P. J., Floria, L. M., Falo, F.
We study numerically synchronization phenomena of mobile discrete breathers in dissipative nonlinear lattices periodically forced. When varying the driving intensity, the breather velocity...
Garcia-Palacios, J. L., Zueco, D.
The continued-fraction method to solve classical Fokker--Planck equations has been adapted to tackle quantum master equations of the Caldeira--Leggett type. This can be done taking advantage of the...
