Prof. Dr Ilya Eremin, Ruhr-Universität Bochum On Zoom Prof. Eremin will discuss the mechanisms of unconventional superconductivity in which magnetic correlations are playing a crucial role for certain types of unconventional superconductors. A central focus will be iron-based, cuprate and most recently nickelate superconductors. I will present the historical overview of the field and present Read More
Jukka Vayrynen, Assistant Professor of Physics and Astronomy, Purdue University In-person and on zoom (recording available for FLEET members only) The critical current of a superconducting wire can be non-reciprocal, that is, dependent on current direction, when inversion and time-reversal symmetry are broken. This so-called superconducting diode effect has gained renewed attention in recent years, Read More
Päivi Törmä, Department of Applied Physics, Aalto University, Finland Catch up on YouTube We have found that superconductivity and superfluidity have a connection to quantum geometry [1,2]. Namely, the superfluid weight in a multiband system has a previously unnoticed component which we call the geometric contribution. It is proportional to the minimal quantum metric of Read More
Prof. Andrey Chubukov, Department of Physics, University of Minnesota Catch up on YouTube In this colloquium, I will review recent and not so recent works that aim to understand whether a nominally repulsive Coulomb interaction can give rise to superconductivity. I discuss a generic scenario of the pairing, put forward by Kohn and Luttinger back Read More
