Dissipative two-identical-particle systems: diffraction and interference

2021-02-12T10:08:13+01:00Tags: , |

Authors: Mousavi, S. V.; Miret-Artes, S. Contribution: Article Journal: EUROPEAN PHYSICAL JOURNAL PLUS Publication date: 2020/01/17 DOI: 10.1140/epjp/s13360-020-00125-0 Abstract: Interference and diffraction of two-identical-particles are considered in the context of open quantum systems. This theoretical study is carried out within two approaches, the effective time-dependent Hamiltonian due to Caldirola-Kanai (CK) and the Caldeira-Leggett (CL) one where [...]

Authors: Mousavi, S., V; Miret-Artes, S. Contribution: Article Journal: EUROPEAN PHYSICAL JOURNAL PLUS Publication date: 2020/03/23 DOI: 10.1140/epjp/s13360-020-00336-5 Abstract: Dissipative backflow is studied in the context of open quantum systems. This theoretical analysis is carried out within two frameworks, the effective time-dependent Hamiltonian due to Caldirola-Kanai (CK) and the Caldeira-Leggett (CL) one where a master equation [...]

Joint theoretical and experimental study on elastic electron scattering from bismuth

2021-02-12T10:08:12+01:00Tags: , , |

Authors: Predojevic, B.; Sevic, D.; Marinkovic, B. P.; McEachran, R. P.; Blanco, F.; Garcia, G.; Brunger, M. J. Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2020/03/23 DOI: 10.1103/PhysRevA.101.032704 Abstract: We report on experimental elastic differential and integral cross sections for electron scattering from bismuth. The energy range of those measurements is 10-100 eV, while the [...]

Gamma-Rays from Kilonovae and the Cosmic Gamma-Ray Background

2021-02-12T10:08:12+01:00Tags: |

Authors: Ruiz-Lapuente, Pilar; Korobkin, Oleg Contribution: Article Journal: ASTROPHYSICAL JOURNAL Publication date: 2020/03/20 DOI: 10.3847/1538-4357/ab744e Abstract: The recent detection of the gravitational-wave event GW170817, produced by the coalescence of two neutron stars, and of its optical-infrared counterpart, powered by the radioactive decay of r-process elements, has opened a new window onto gamma-ray astronomy: the direct detection [...]

Mediator-assisted cooling in quantum annealing

2021-02-12T10:08:12+01:00Tags: , , |

Authors: Pino, M.; Garcia-Ripoll, Juan J. Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2020/03/18 DOI: 10.1103/PhysRevA.101.032324 Abstract: We show a significant reduction of errors for an architecture of quantum annealers where bosonic modes mediate the interaction between qubits. These systems have a large redundancy in the subspace of solutions, supported by arbitrarily large bosonic occupations. [...]

Origin of the Electron-Phonon Interaction of Topological Semimetal Surfaces Measured with Helium Atom Scattering

2021-02-12T10:08:12+01:00Tags: , , , , |

Authors: Benedek, Giorgio; Miret-Artes, Salvador; Manson, J. R.; Ruckhofer, Adrian; Ernst, Wolfgang E.; Tamtoegl, Anton Contribution: Article Journal: JOURNAL OF PHYSICAL CHEMISTRY LETTERS Publication date: 2020/03/05 DOI: 10.1021/acs.jpclett.9b03829 Abstract: He atom scattering has been demonstrated to be a sensitive probe of the electron-phonon interaction parameter lambda at metal and metal-overlayer surfaces. Here it is shown that [...]

Theoretical priors in scalar-tensor cosmologies: Thawing quintessence

2021-02-12T10:08:12+01:00Tags: , |

Authors: Garcia-Garcia, Carlos; Bellini, Emilio; Ferreira, Pedro G.; Traykova, Dina; Zumalacarregui, Miguel Contribution: Article Journal: PHYSICAL REVIEW D Publication date: 2020/03/05 DOI: 10.1103/PhysRevD.101.063508 Abstract: The late time acceleration of the Universe can be characterized in terms of an extra, time-dependent, component of the Universe-dark energy. The simplest proposal for dark energy is a scalar-tensor theory-quintessence-which consists [...]

Rotational spectroscopy and astronomical search for glutaronitrile

2021-02-12T10:08:11+01:00Tags: |

Authors: Cabezas, C.; Bermúdez, C.; Endo, Y.; Tercero, B.; Cernicharo, J. Contribution: Article Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2020/04/10 DOI: 10.1051/0004-6361/202037769 Abstract: Context. Nitriles constitute almost 15% of the molecules observed in the interstellar medium (ISM), surprisingly only two dinitriles have been detected in the ISM so far. The lack of astronomical detections for dinitriles [...]
