Systems of granular
superconductors
A new type of particle detector and low energy radiation
is based on the detection of the transition, induced
by the incident radiation, of superconductor to normal
in a metastable superconductor material. The study of
these systems has both applied and fundamental interest,
and involves calculations of transitions in the presence
of magnetic fields. Among the topics we are interested
on are:
- Characterization of the response of superconductor
systems of granular type (SSG). We study the dynamics
of these transitions under increments of the applied
magnetic field. Then we plan to study the effect of
radiation.
- Evaluation of the parameters of Ginzburg-Landau
in granular superconductors. This requires simulating
transitions with a decreasing magnetic field.
- Bidimensional magnetic systems. The penetration
of magnetic field lines in superconducting films present
very interesting morphologies. We plan to study this
case with a phase-field model.
