Estimación del aporte de contaminantes de la balsa de fosfoyesos al Estuario de Huelva
Pérez López, Rafael
; Miguel Sarmiento, Aguasanta; Carrero Romero, Sergio; Cruz Hernández, Pablo; Macías Suárez, Francisco; Nieto Liñán, José Miguel; Bolívar Raya, Juan Pedro (Sociedad Española de Mineralogía, 2014)
La producción de ácido fosfórico mediante ataque húmedo en el Polo Químico de Huelva conduce a la acumulación de un sub-producto conocido como fosfoyeso. El fosfoyeso contiene impurezas de metales tóxicos y radionucleidos. ... -
Design of a multi-harmonic buncher for lince
Bontoiu, Cristian; Dueñas Díaz, José Antonio; Labrador Berna, Juan Ángel; Martel Bravo, Ismael; Garbayo, Alberto; Carrera, Miguel Ángel; Camargo Villari, Antonio Carlos (Helmholtz-Zentrum Dresden-Rossendorf, 2014)
Continuous beams delivered by the LINCE [1] ECR ions source will be bunched by a multi-harmonic buncher in order to be injected into an RFQ. Its numerical design is reported along with electric field maps and beam ... -
The influence of intruder states in even-even Po isotopes
García Ramos, José Enrique; Heyde, K. (2015-09-23)
We study the role of intruder states and shape coexistence in the even-even Po isotopes, through an interacting boson model with configuration mixing calculation. We analyzed the results in the light of known systematics ... -
Economic growth, renewable energy and CO2 emissions: the Kaya identity and the environmental Kuznets curve
García Ramos, José Enrique; Golpe Moya, Antonio Aníbal; Mena Nieto, Ángel Isidro; Robalino López, Andrés (2015-07)
This contribution presents a model for estimating CO2 emissions in a given country for a near future. The model is based on a modification of the Kaya identity that allows to connect gross domestic product, productive ... -
Quantum Phase Transitions in Coupled Systems : an application of Catastrophe Theory
Two-fluid algebraic models are of great interest in the context of quantum phase transition in nuclei. We intend to study the phase diagram of a two-fluid Lipkin model that resembles a nuclear proton-neutron interacting ... -
The platinum nuclei : concealed configuration mixing and shape coexistence
García Ramos, José Enrique; Hellemans, V.; Heyde, K. (World Scientific, 2013)
The role of configuration mixing in the Pt region is investigated. For this chain of isotopes, the nature of the ground state changes smoothly, being spherical around mass A ∼ 174 and A ∼ 192 and deformed around the mid-shell ... -
Concealed configuration mixing and shape coexistence in the platinum nuclei
García Ramos, José Enrique; Hellemans, V.; Heyde, K. (American Institute of Physics, 2012)
The role of configuration mixing in the Pt region is investigated. The nature of the ground state changes smoothly, being spherical around mass A 174 and A 192 and deformed around the mid-shell N = 104 region. ... -
Excited state quantum phase transitions and chaos in the Dicke model
Pérez Fernández, Pedro; Relaño Pérez, Armando; Cejnar, P.; Arias Carrasco, José Miguel; Dukelsky, J.; García Ramos, José Enrique (American Institute of Physics, 2012)
In this contribution, the critical behavior of excited state quantum phase transitions (ESQPT’s) and its relation to order and chaos in the Dicke model are studied. This model is nonintegrable. For comparison, the same ... -
Decoherence and quantum quench: their relationship with excited state quantum phase transitions
García Ramos, José Enrique; Arias Carrasco, José Miguel; Cejnar, P.; Dukelsky, J.; Pérez Fernández, Pedro; Relaño Pérez, Armando (American Institute of Physics, 2012-05)
We study the similarities and differences between the phenomena of Quantum Decoherence and Quantum Quench in presence of an Excited State Quantum Phase Transition (ESQPT).We analyze, on one hand, the decoherence induced ...
