Title: Magnetism and Superconductivity: Making them coexist

Speaker: Dr. Madhuparna Karmakar, IIT Madras, Chennai

Abstract: Superconductivity and magnetism are generally competing orders in a material, with superconductivity preferring pairing between time-reversed states and magnetism breaking the time reversal symmetry. This talk discusses about situations which are counter intuitive to this general understanding of ours. I would talk about specific classes of materials where magnetism coexists with superconductivity. The talk would shed light on a numerical technique which can take into account the effect of fluctuations at non zero temperature and gives accurate estimation of the thermal scales associated with the system. I would discuss about the non trivial aspects of the thermodynamic and fermionic features that comes into life when fluctuations associated with competing orders coexist and talk to each other.
