Quantum electrodynamics in anisotropic and tilted Dirac photonic lattices

Marcelo Castellanos2021-10-01T20:21:00+02:00Tags: Multidisciplinary. , Physics|

Authors: Redondo-Yuste, Jaime; Blanco de Paz, Maria; Huidobro, Paloma A.; Gonzalez-Tudela, Alejandro Journal: NEW JOURNAL OF PHYSICS Publication date: 2021/10/01 DOI: 10.1088/1367-2630/ac27e0 Abstract: One of the most striking predictions of quantum electrodynamics is that vacuum fluctuations of the electromagnetic field can lead to spontaneous emission of atoms as well as photon-mediated interactions among them. Since [...]

Authors: Altares-Lopez, Sergio; Ribeiro, Angela; Garcia-Ripoll, Juan Jose Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2021/10/01 DOI: 10.1088/2058-9565/ac1ab1 Abstract: We propose a new technique for the automatic generation of optimal ad-hoc ansatze for classification by using quantum support vector machine. This efficient method is based on non-sorted genetic algorithm II multiobjective genetic algorithms which allow [...]

Theoretical priors in scalar-tensor cosmologies: Shift-symmetric Horndeski models

Marcelo Castellanos2022-04-05T17:40:55+02:00Tags: Astronomy & Astrophysics; Physics, Particles & Fields. |

Authors: Traykova, Dina; Bellini, Emilio; Ferreira, Pedro G.; Garcia-Garcia, Carlos; Noller, Johannes; Zumalacarregui, Miguel Journal: PHYSICAL REVIEW D Publication date: 2021/10/01 DOI: 10.1103/PhysRevD.104.083502 Abstract: Attempts at constraining theories of late time accelerated expansion often assume broad priors for the parameters in their phenomenological description. Focusing on shift-symmetric scalar-tensor theories with standard gravitational wave speed, we [...]
