Tsunamis and Tsunami Hazards in Central America
(2000-02)
A tsunami catalogue for Central America is compiled containing 49 tsunamis for the
period 1539–1996, thirty seven of them are in the Pacific and twelve in the Caribbean. At the Caribbean side, 5 events are related with ...
A thermodynamic cycle for the solar cell
(2017-01-06)
A solar cell is a heat engine, but textbook treatments are not wholly satisfactory from a thermodynamic standpoint, since they present solar cells as directly converting the energy of light into electricity, and the current ...
Irreversibility in an ideal fluid
(2014-10)
When a real fluid is expelled quickly from a tube, it forms a jet separated from the surrounding fluid by a thin, turbulent layer. On the other hand, when the same fluid is sucked into the tube, it comes in from all ...
Chandler wobble: Stochastic and deterministic dynamics
(2016-09-18)
We propose a model of the Earth’s torqueless precession, the “Chandler wobble,” as a self-oscillation driven by positive feedback between the wobble and the centrifugal deformation of the portion of the Earth’s mass contained ...
Interaction of a quantum field with a rotating heat bath
(2018-08-01)
The linear coupling of a rotating heat bath to a quantum field is studied in the framework of the Markovian master equation for the field's non-unitary time evolution. The bath's rotation induces population inversion for ...
Irreversibility of mechanical and hydrodynamic instabilities
(2017-12-01)
The literature on dynamical systems has, for the most part, considered self-oscillators (i.e., systems capable of generating and maintaining a periodic motion at the expense of an external energy source with no corresponding ...
Diseño y caracterización de un enfriador de átomos de tipo “desacelerador Zeeman”
(2016)
Nosotros presentamos un método que utiliza simultáneamente dos modelos matemáticos, con el objetivo de optimizar el diseño de un desacelerador Zeeman, con miras a la implementación de átomos ultrafríos a la física del ...
The early rainy season in Central America: the role of thetropical North Atlantic SSTs
(2016)
We explored the relationship between the precipitation anomalies during May to June as the first peak of the rainy season in the Pacific slope of Central America, and sea surface temperature (SST) fluctuations in the ...
