We analyze the absorption of a weak probe field in singly charged n-doped quantum dots in the presence of an external magnetic field in the Voigt geometry. The dots are modeled as double lambda systems. A laser field pumps two of the four active[...]texto impreso
BP Tau is one of the few classical T Tauri stars for which the presence of a hot spot in the surface has been reported without ambiguity. The most likely source of heating is gravitational energy released by the accreting material as it shocks w[...]texto impreso
López Santiago, Javier ; Miceli, M. ; Valle, M. V. del ; Romero, G. E. ; Bonito, R. ; Albacete Colombo, J. F. ; Pereira, V. ; Castro Rubio, Elisa de ; Damiani, F. | IOP Publishing | 2012-09-20Runaway stars produce shocks when passing through interstellar medium at supersonic velocities. Bow shocks have been detected in the mid-infrared for several high-mass runaway stars and in radio waves for one star. Theoretical models predict the[...]texto impreso
AK Sco is a unique source: a similar to 10 Myr old pre-main-sequence (PMS) spectroscopic binary composed of two nearly equal F5 stars that at periastron are separated by barely 11 stellar radii, so the stellar magnetospheres fill the Roche lobe [...]texto impreso
The complex reflected and transmitted amplitudes from a Fabry-Perot interferometer are analysed using a phase-space approach, in which the real and imaginary parts of those amplitudes are taken as basic variables. As functions of the optical pat[...]texto impreso
Using new UV magnitudes for a sample of early-type galaxies (ETGs) with published stellar mass-to-light ratios, ?_*, we find a correlation between UV color and ?_* that is tighter than those previously identified between ?_* and either the centr[...]texto impreso
Gutiérrez-Alonso, Gabriel ; Gutiérrez Marco, Juan Carlos ; Fernández Suárez, Javier ; Bernárdez Rodríguez, Enrique ; Corfu, F. ; López Carmona, Alicia | IOP Publishing | 2019Zircon and monazite ID-TIMS U-Pb dating of four Lower Ordovician altered ash-fall tuff beds (K-Bentonites) in NW Iberia provided coetaneous ages of 477.5±1, 477±1.3 Ma, 477.2±1.1 Ma and 477.3±1 Ma, with a pooled concordia age of 477.2±0.74 Ma. A[...]texto impreso
Mazza, Leonardo ; Bermudez, Alejandro ; Goldman, Nathan ; Rizzi, Matteo ; Martín-Delgado Alcántara, Miguel Ángel ; Lewenstein, Maciej | IOP Publishing | 2012-01-31We present a proposal for a versatile cold-atom-based quantum simulator of relativistic fermionic theories and topological insulators in arbitrary dimensions. The setup consists of a spin-independent optical lattice that traps a collection of hy[...]texto impreso
Arganda, E. ; Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP Publishing | 2011-06The Pierre Auger Collaboration has reported. evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > E-th = 5.5 x 10(19) eV. These show a correlation with the distribution of nearby extragalactic o[...]texto impreso
Grassie, Alexander D. C. ; Agapito Serrano, Juan Andrés ; Gonzalez Espeso, Pablo | IOP Publishing | 1979An excess resistivity has been observed in thin film polycrystalline samples of SnTe with low carrier concentration and is attributed to the additional scattering due to the phonon softening associated with the structural phase transition.texto impreso
The center of our Galaxy is a complex region characterized by extreme phenomena. The presence of the supermassive Sagittarius A* black hole, a high dark matter density and an even higher baryonic density are able to produce very energetic proces[...]texto impreso
Antón Revilla, Miguel Ángel ; Gonzalo Fonrodona, Isabel ; Carreño Sánchez, Fernando | IOP Publishing | 2021-01-16Entanglement generation and control of two spatially separated asymmetric quantum dots with broken inversion symmetry and mediated by a photonic cavity is studied using a quantum master equation formalism. The quantum dots are coherently driven [...]texto impreso
Muñoz de Nova, Juan Ramón ; Guéry Odelin, D. ; Sols Lucía, Fernando ; Zapata, I. | IOP Publishing | 2014-12-15We study the evolution of an initially confined atom condensate, which is progressively outcoupled by gradually lowering the confining barrier on one side. The goal is to identify protocols that best lead to a quasi-stationary sonic black hole s[...]texto impreso
We analyze the star-forming and structural properties of 45 massive (log(M/M_) > 10) compact star-forming galaxies (SFGs) at 2texto impreso
Toloba, E. ; Sánchez Blázquez, P. ; Gorgas García, Francisco Javier ; Gibson, B. K. | IOP Publishing | 2009-02-01For the first time, we undertake a systematic examination of the nitrogen abundances using the NH3360 feature for a sample of 35 early-type galaxies spanning a range of masses and local environment. The nitrogen-sensitive molecular feature at 33[...]
