Multi-emitter oscillating bound states in Waveguide QED
Sergi Terradas-Briansó, Carlos A. González-Gutiérrez, Iván Huarte +2
Waveguide quantum electrodynamics platforms have emerged as promising candidates for exploring and implementing non-Markovian quantum phenomena. In this work, we investigate the fo…
Influence of Non-Markovian Dynamics in Thermal-Equilibrium Uncertainty-Relations
Leonardo A. Pachon, Johan F. Triana, David Zueco +1
Contrary to the conventional wisdom that deviations from standard thermodynamics originate from the strong coupling to the bath, it is shown that in quantum mechanics, these deviat…
Entanglement and Disentanglement in Circuit QED Architectures
David Zueco, Georg M. Reuther, Peter Hänggi +1
We propose a protocol for creating entanglement within a dissipative circuit QED network architecture that consists of two electromagnetic circuits (cavities) and two superconducti…
Spin squeezing by one-photon-two-atom excitations processes in atomic ensembles
Vincenzo MacrÃ, Franco Nori, Salvatore Savasta +1
It has been shown elsewhere that two spatially separated atoms can jointly absorb one photon, whose frequency is equal to the sum of the transition frequencies of the two atoms. We…
Quantum and statistical mechanics in open systems: theory and examples
David Zueco
Using the system-bath model Hamiltonian this thesis covers the equilibrium and out of equilibrium properties of quantum open systems. Topics included are the calculation of thermod…
First- and second-order quantum phase transitions in the long-range unfrustrated antiferromagnetic Ising chain
VÃctor Herráiz-López, Sebastián Roca-Jerat, Manuel Gallego +4
We study the ground-state phase diagram of an unfrustrated antiferromagnetic Ising chain with longitudinal and transverse fields in the full range of interactions: from all-to-all…
