Non-adiabatic quantum dynamics of the electronic quenching OH(A(2)sigma(+)) + Kr

2020-08-14T20:20:00+02:00Tags: , , , |

Authors: Gamallo, Pablo; Zanchet, Alexandre; Aoiz, F. Javier; Petrongolo, Carlo Contribution: Article Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2020/08/14 DOI: 10.1039/d0cp02512g Abstract: We present the dynamics of the electronic quenching OH(A(2)sigma(+)) + Kr(S-1) -> OH(X-2 pi) + Kr(S-1), with OH(A(2)sigma(+)) in the ground ro-vibrational state. This study relies on a new non-adiabatic quantum theory that [...]

Theory of waveguide QED with moving emitters

2020-07-28T20:20:00+02:00Tags: , , |

Authors: Sanchez-Burillo, Eduardo; Gonzalez-Tudela, Alejandro; Gonzalez-Ballestero, Carlos Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2020/07/28 DOI: 10.1103/PhysRevA.102.013726 Abstract: We theoretically study a system composed of a waveguide and a quantum emitter moving in a one-dimensional potential along the waveguide axis. We focus on the single-excitation subspace and treat the emitter motional degrees of freedom fully [...]

Seeing topological edge and bulk currents in time-of-flight images

2020-07-23T20:20:00+02:00Tags: , , , |

Authors: Rubio-Garcia, Alvaro; Self, Chris N.; Jose Garcia-Ripoll, Juan; Pachos, Jiannis K. Contribution: Article Journal: PHYSICAL REVIEW B Publication date: 2020/07/23 DOI: 10.1103/PhysRevB.102.041123 Abstract: Here we provide a general methodology to directly measure the topological currents emerging in the optical lattice implementation of the Haldane model. Alongside the edge currents supported by gapless edge states, transverse [...]

Topological bulk states and their currents

2020-07-23T20:20:00+02:00Tags: , , , |

Authors: Self, Chris N.; Rubio-Garcia, Alvaro; Jose Garcia-Ripoll, Juan; Pachos, Jiannis K. Contribution: Article Journal: PHYSICAL REVIEW B Publication date: 2020/07/23 DOI: 10.1103/PhysRevB.102.045424 Abstract: We provide evidence that, alongside topologically protected edge states, two-dimensional Chern insulators also support localized bulk states deep in their valence and conduction bands. These states manifest when local potential gradients are [...]

The millimeter-wave spectrum and astronomical search for ethyl methyl sulfide

2020-07-21T20:20:00+02:00Tags: |

Authors: Cabezas, C.; Bermudez, C.; Tercero, B.; Cernicharo, J. Contribution: Article Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2020/07/21 DOI: 10.1051/0004-6361/202038177 Abstract: Context. Sulfur-containing molecules constitute only 8% of the molecules observed in the interstellar medium (ISM), in spite of the fact that sulfur has been shown to be an abundant element in the ISM. In order [...]

Interference of a resonance state with itself: a route to control its dynamical behaviour

2020-07-14T20:20:00+02:00Tags: , , , |

Authors: Garcia-Vela, A. Contribution: Article Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2020/07/14 DOI: 10.1039/d0cp00392a Abstract: It is demonstrated both numerically and mathematically that the dynamical behavior of an isolated resonance state, which comprises the resonance decay lifetime and the asymptotic fragment state distribution produced upon resonance decay, can be extensively controlled by means of quantum [...]

Limits of photon-mediated interactions in one-dimensional photonic baths

2020-07-08T20:20:00+02:00Tags: , , |

Authors: Sanchez-Burillo, Eduardo; Porras, Diego; Gonzalez-Tudela, Alejandro Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2020/07/08 DOI: 10.1103/PhysRevA.102.013709 Abstract: The exchange of off-resonant propagating photons between distant quantum emitters induces coherent interactions among them. The range of such interactions, and whether they are accompanied by dissipation, depends on the photonic energy dispersion, its dimensionality, and/or the [...]
