Galan, Pablo ; Garay Elizondo, Luis Javier ; Mena Marugán, Guillermo A. | Amer Physical Soc | 2007-08The combined action of gravity and quantum mechanics gives rise to a minimum time uncertainty in the lowest order approximation of a perturbative scheme, in which quantum effects are regarded as corrections to the classical spacetime geometry. F[...]texto impreso
We perform a quasinormal mode analysis of black-hole configurations in Bose-Einstein condensates (BECs). In this analysis we use the full Bogoliubov dispersion relation, not just the hydrodynamic or geometric approximation. We restrict our atten[...]texto impreso
Valtierra, Iván F. ; Klimov, A.B. ; Leuchs, Gerd ; Sánchez Soto, Luis Lorenzo | Amer Physical Soc | 2020-03-02We present analytic expressions for the s-parametrized currents on the sphere for both unitary and dissipative evolutions. We examine the spatial distribution of the flow generated by these currents for quadratic Hamiltonians. The results are ap[...]texto impreso
Blázquez Salcedo, José Luis ; Kunz, Jutta ; Navarro Lérida, Francisco ; Radu, Eugen | Amer Physical Soc | 2015-08-17Rotating black holes in Einstein-Maxwell-Chern-Simons theory possess remarkable features when the Chern-Simons coupling constant reaches a critical value. Representing single asymptotically flat black holes with horizons of spherical topology, t[...]texto impreso
Jarillo, Javier ; García Villaluenga, Juan Pedro ; Cao García, Francisco Javier | Amer Physical Soc | 2018-09-04Brownian ratchets are small-scale systems which rectify thermal fluctuations to produce a net current of particles. They have inspired many models of molecular motors that perform transport in the noisy environment of living cells. For the most [...]texto impreso
Castaño Tierno, Antonio ; Mohino Harris, Elsa ; Rodríguez Fonseca, María Belén ; Losada Doval, Teresa | Amer Physical Soc | 2018-12-16The thermocline is defined as the ocean layer for which the vertical thermal gradient is maximum. In the equatorial ocean, observations led to the use of the 20 °C isotherm depth (z20) as an estimate of the thermocline. This study compares z20 a[...]texto impreso
In the framework of general relativity, a description of the matching conditions between two rotating perfect fluids spacetimes in terms of the kinematical properties of the fluids is introduced. The Einstein and Darmois equations are written us[...]texto impreso
Gómez Nicola, Ángel ; Peláez Sagredo, José Ramón ; Ruiz de Elvira, Jacobo | Amer Physical Soc | 2013-01-02We analyze the properties of four-quark condensates and scalar susceptibilities in the meson gas, within finite temperature chiral perturbation theory (ChPT). The breaking of the factorization hypothesis does not allow for a finite four-quark co[...]texto impreso
The imaginary time generating functional Z for the assless Schwinger model at nonzero chemical potential mu and temperature T is studied in a torus with spatial length L. The lack of Hermiticity of the Dirac operator gives rise to a nontrivial [...]texto impreso
Arganda, E. ; Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2011-12-30The Surface Detector of the Pierre Auger Observatory is sensitive to neutrinos of all flavors above 0.1 EeV. These interact through charged and neutral currents in the atmosphere giving rise to extensive air showers. When interacting deeply in t[...]texto impreso
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2016-10-03We present a search for ultrarelativistic magnetic monopoles with the Pierre Auger observatory. Such particles, possibly a relic of phase transitions in the early Universe, would deposit a large amount of energy along their path through the atmo[...]texto impreso
We analyze the Hawking radiation process due to collapsing configurations in the presence of superluminal modifications of the dispersion relation. With such superluminal dispersion relations, the horizon effectively becomes a frequency-dependen[...]texto impreso
Coulomb-excitation experiments to study electromagnetic properties of radioactive even-even Hg isotopes were performed with 2.85 MeV=nucleon mercury beams from REX-ISOLDE. Magnitudes and relative signs of the reduced E2 matrix elements that coup[...]texto impreso
The beta decay of Pb-192,Pb-190 has been studied using the total absorption technique at the ISOLDE (CERN) facility. The beta-decay strength deduced from the measurements, combined with QRPA theoretical calculations, allow us to infer that the g[...]texto impreso
Chinea Trujillo, Francisco Javier ; Fernández Jambrina, Leonardo ; Senovilla, J. M. M. | Amer Physical Soc | 1992-01-15We show that the solution published in the paper by Senovilla [Phys. Rev. Lett. 64, 2219 (1990)] is geodesically complete and singularity-free. We also prove that the solution satisfies the stronger energy and causality conditions, such as globa[...]
