M3-7 Jules Carbotte Memorial (DCMMP) / En mémoire de Jules Carbotte (DPMCM)
- Michel Gingras
High-temperature superconductor YBa2Cu3O7 (YBCO) can be systematically disordered by irradiating with a He-ion beams to induce a metal-insulator transition (MIT). Therefore, tunnel junctions demonstrating Josephson tunneling properties can be constructed in planar YBCO films using a He-ion microscope. We have used superconducting loops with disordered YBCO junctions to develop devices that...
I was a graduate student in Jules Carbotte's group in the early 1990s, during the heyday of high temperature superconductivity. At the time (for me), everything was new and everything was exciting and it felt as if we were about to learn something beautiful about the world. I recognize now how many of those feelings are tied to where I was and who I was working for. Indeed, I have much to...
This talk will focus on an overview of Eliashberg theory, a formalism that Jules was very well known for. But I will also discuss some potential shortcomings of this framework, as time permits, from the weak coupling to the strong coupling limit, with polaron physics, and applicability to the hydride and superhydride materials.
