Walter de Siqueira Pedra (Mainz, Germany): "Microscopic Foundations of the Meissner Effect - Thermodynamic Aspects"
Friday 26 April 2013, 10:50 - 11:35
Amphi Hermite


In a joint work with Jean-Bernard Bru we analyze thermodynamic aspects of the Meissner effect from first principles of quantum mechanics. At low temperature, we show the existence of superconducting states minimizing the magnetic free-energy of a BCS-like model and carrying surface currents which annihilate the total magnetic induction inside the bulk in the thermodynamic limit.
