Closed timelike curves and chronology protection in quantum and classical simulators

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

Authors: Martin-Vazquez, Gonzalo; Sabin, Carlos Contribution: Article Journal: CLASSICAL AND QUANTUM GRAVITY Publication date: 2020/02/20 DOI: 10.1088/1361-6382/ab5f3f Abstract: In principe, general relativity seems to allow the existence of closed timelike curves (CTC). However, when quantum effects are considered, it is likely that their existence is prevented by some kind of chronological protection mechanism, as Hawking conjectured. [...]

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 [...]

Authors: Melnick, Gary J.; Tolls, Volker; Snell, Ronald L.; Kaufman, Michael J.; Bergin, Edwin A.; Goicoechea, Javier R.; Goldsmith, Paul F.; Gonzalez-Alfonso, Eduardo; Hollenbach, David J.; Lis, Dariusz C.; Neufeld, David A. Contribution: Article Journal: ASTROPHYSICAL JOURNAL Publication date: 2020/03/20 DOI: 10.3847/1538-4357/ab77b4 Abstract: The depth-dependent abundance of both gas-phase and solid-state water within dense, quiescent, molecular [...]

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 [...]

Dissipative quantum backflow

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

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 [...]
