Authors: Chanda, Titas; Gonzalez-Cuadra, Daniel; Lewenstein, Maciej; Tagliacozzo, Luca; Zakrzewski, Jakub Journal: SCIPOST PHYSICS Publication date: 2022/02/01 DOI: 10.21468/SciPostPhys.12.2.076 Abstract: We consider a mixture of ultracold bosonic atoms on a one-dimensional lattice described by the XXZ-Bose-Hubbard model, where the tunneling of one species depends on the spin state of a second deeply trapped species. We [...]

Ultrastrong Capacitive Coupling of Flux Qubits

Authors: Hita-Perez, Maria; Jauma, Gabriel; Pino, Manuel; Garcia-Ripoll, Juan Jose Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/01/24 DOI: 10.1103/PhysRevApplied.17.014028 Abstract: A flux qubit can interact strongly when it is capacitively coupled to other circuit elements. This interaction can be separated into two parts, one acting on the qubit subspaces and one in which excited states [...]

On some unexplored decoherence aspects in the Caldeira-Leggett formalism: arrival time distributions, identical particles and diffraction in time

2022-06-17T17:15:52+02:00Tags: , |

Authors: Mousavi, S., V; Miret-Artes, S. Journal: EUROPEAN PHYSICAL JOURNAL PLUS Publication date: 2022/01/19 DOI: 10.1140/epjp/s13360-022-02367-6 Abstract: Some unexplored decoherence aspects within the Caldeira-Leggett master equation are analyzed and discussed. The decoherence process is controlled by the two environment parameters, the relaxation rate or friction and the temperature, leading to a gradual transition from the [...]

Authors: Garcia-Abenza, A.; No, J. M. Journal: EUROPEAN PHYSICAL JOURNAL C Publication date: 2022/02/01 DOI: 10.1140/epjc/s10052-022-10089-3 Abstract: High-energy ( )gamma gamma colliders constitute a potential running mode of future lepton colliders such as the ILC and CLIC. We study the sensitivity of a high-energy gamma gamma collider to the Higgs portal scenario to a hidden [...]

Benchmarking quantum annealing dynamics: The spin-vector Langevin model

Authors: Subires, David; Gomez-Ruiz, Fernando J.; Ruiz-Garcia, Antonia; Alonso, Daniel; del Campo, Adolfo Journal: PHYSICAL REVIEW RESEARCH Publication date: 2022/05/09 DOI: 10.1103/PhysRevResearch.4.023104 Abstract: The classical spin-vector Monte Carlo (SVMC) model is a reference benchmark for the performance of a quantum annealer. Yet, as a Monte Carlo method, SVMC is unsuited for an accurate description of [...]

Authors: Abah, Obinna; De Chiara, Gabriele; Paternostro, Mauro; Puebla, Ricardo Journal: PHYSICAL REVIEW RESEARCH Publication date: 2022/04/22 DOI: 10.1103/PhysRevResearch.4.L022017 Abstract: Crossing a quantum critical point in finite time challenges the adiabatic condition due to the closing of the energy gap, which ultimately results in the formation of excitations. Such nonadiabatic excitations are typically deemed detrimental [...]
