Bridging the gap between topological non-Hermitian physics and open quantum systems

2022-07-25T20:22:00+02:00Tags: |

Authors: Gomez-Leon, Alvaro; Ramos, Tomas; Gonzalez-Tudela, Alejandro; Porras, Diego Journal: PHYSICAL REVIEW A Publication date: 2022/07/25 DOI: 10.1103/PhysRevA.106.L011501 Abstract: We relate observables in open quantum systems with the topology of non-Hermitian models using the Keldysh path-integral method. This allows to extract an effective Hamiltonian from the Green's function which contains all the relevant topological information [...]

Unconventional mechanism of virtual-state population through dissipation

2022-07-22T20:22:00+02:00Tags: |

Authors: Vivas-Viana, Alejandro; Gonzalez-Tudela, Alejandro; Sanchez Munoz, Carlos Journal: PHYSICAL REVIEW A Publication date: 2022/07/22 DOI: 10.1103/PhysRevA.106.012217 Abstract: Virtual states are a central concept in quantum mechanics. By definition, the probability of finding a quantum system in a virtual state should be vanishingly small at all times. In contrast to this notion, we report a [...]

Atom-surface scattering in the classical multiphonon regime

2022-07-21T20:22:00+02:00Tags: |

Authors: Manson, J. R.; Miret-Artes, S. Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/07/21 DOI: 10.1039/d2cp01144a Abstract: Many experiments that utilize beams of incident atoms colliding with surfaces as a probe of surface properties are carried out at large energies, high temperatures and with large mass atoms. Under these conditions the scattering process does not [...]

Authors: Saberi, M.; Khouri, T.; Velilla-Prieto, L.; Fonfria, J. P.; Vlemmings, W. H. T.; Wedemeyer, S. Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2022/07/13 DOI: 10.1051/0004-6361/202141704 Abstract: The nucleosynthesis production of fluorine (F) is still a matter of debate. Asymptotic giant branch (AGB) stars are one of the main candidates for F production. However, their contribution [...]
