The Courtyard of Science 2017

Program of the Courtyard of Science 2017.

V International Course Science takes the floor: the social problems of the pseudosciences in time of information

from 6 to 8 of September 2017.
This course can be recognize by 2 credits of departmental or non-departmental elective courses for the students of the UA or by a 20 hour certificate of the ICE (Institute of Sciences of the Education) with a cost of 30 €. Already it has opened the term of prescription and enrolment.




Colloquia of Physics. (Science of today)

Ninth edition of Physics Colloquium with "Seismic Risk. Prediction or Prevention. Perspective from the Physics of the Earth" given by the University of Alicante's professor, Sergio Molina Palacios.

Professor Molina initiated a line of investigation in Seismic Dangerousness in his doctoral thesis that was the starting point to establish a collaboration between the UA and the research center NORSAR (Kjeller, Norway). This collaboration allowed him develop the tool of free code SELENA, widely used to world-wide level, for the calculation of the seismic risk.

This colloquium is opened to all public and especially to the students of first course of Physics of the UA.

The colloquium will take place in classroom 3, phase 2, of the Faculty of Science, University of Alicante, wednesday the 17 of  March, at 11:30 am. The place of the event will be communicated later.

In many Experimental situations the diagonal and non-diagonal elements of dielectric permittivity tensor vary with the time originating time-dependent Faraday rotation (TDFR).

TDFR Have been used, based on to left (right) circularly polarized pump-probe technique,for investigation of spin relaxation processes of to system using to continuous laser _eld [1] or laser press ace linear marry [2], or to study the and_ect of electron phonon coupling in metals undergoing thermal transport [3]. In this technique To pump press is used to arouse the sample, changing the optical properties while to second time-delayed probe press measures the change.

Under far primary attention have been focused on systems with time dependent diagonal element (refractive index), not giving much attention to the non-diagonal dielectric permittivity term (gyration vector) that can also vary with time. In the present presentation we will discuss To theoretical approach for investigating TDFR in to magnetoactive medium with time dependent dielectric permittivity tensor (diagonal and non-diagonal elements).

We will consider continuous and Press incident laser _eld marry and will show that in to continuous marry Faraday rotation angle increases with time. The latter, in both time dependent diagonal and non-diagonal element marry, shows an increase with periodic oscillations ace either positive (time-dependent dielectric permittivity marry) or negative (time dependent gyration vector marry) and follows to general pattern. Ultrashort Press can scan the time dependent dielectric permittivity through the Faraday rotation angle and can be used to interpret some

Experimental dates of spin-relaxation processes in EuO thin _lms [2].

Colloquia of Physics. (Science of today)

Eighth edition of the colloquia of Physics with "OBSERVATIONAL PROOFS OF THE MODEL OF THE BIG EXPLOSION (BIG BANG) " given by the Dr. Alberto Fernandez Soto, Scientific Headline of the CSIC in the Institute of Physics of Cantabria (CSIC-UC) and co-autor of the book "Origins: The universe, the life, the humans".

This colloquium this opened to the public in general and especially to the students of first course of Physics of the UA.

The colloquium will take place the Friday 17 March, to the 12:00 hours, in the Living room of acts of the Faculty of Science of the University of Alicante.
