Theory of waveguide QED with moving emitters

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

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 [...]

Topological bulk states and their currents

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

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 [...]

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

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 [...]

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

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

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

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 [...]

Tripartite Genuine Non-Gaussian Entanglement in Three-Mode Spontaneous Parametric Down-Conversion

Authors: Agusti, A.; Chang, C. W. Sandbo; Quijandria, F.; Johansson, G.; Wilson, C. M.; Sabin, C. Contribution: Article Journal: PHYSICAL REVIEW LETTERS Publication date: 2020/07/08 DOI: 10.1103/PhysRevLett.125.020502 Abstract: We show that the states generated by a three-mode spontaneous parametric down-conversion (SPDC) interaction Hamiltonian possess tripartite entanglement of a different nature to other paradigmatic three-mode entangled states [...]

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

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

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 [...]

Criegee intermediates meet rotational spectroscopy

Authors: Cabezas, Carlos; Nakajima, Masakazu; Endo, Yasuki Contribution: Review Journal: INTERNATIONAL REVIEWS IN PHYSICAL CHEMISTRY Publication date: 2020/07/02 DOI: 10.1080/0144235X.2020.1782651 Abstract: Carbonyl oxides, R1R2COO, alternatively known as Criegee intermediates (CIs), are short-lived molecules produced from ozonolysis of alkenes. These ozonolysis reactions yield highly excited CIs, and most of them promptly decay with emission of the OH [...]
