EU-Aust colloquium. “Magnetic” mechanisms of unconventional superconductivity: entering the Ni-age

We're sorry, but all tickets sales have ended because the event is expired.

15 May 2024
3:00 pm - 4:00 pm

Prof. Dr Ilya Eremin, Ruhr-Universität Bochum Missed the presentation? Catch up on YouTube 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 Read More

FLEET seminar. Extrinsic and intrinsic superconducting diode effects

10:00 am - 11:00 am

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

US-Europe-AUST Colloqium. Quantum Geometry in flat-band superconductivity, Bose-Einstein condensation, light-matter interactions and nanophotonics

We're sorry, but all tickets sales have ended because the event is expired.

28 Jun 2023
3:00 pm - 4:00 pm

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

US-Aust Colloquium. Twists and turns of superconductivity from a repulsive interaction

We're sorry, but all tickets sales have ended because the event is expired.

26 Apr 2023
10:00 am - 11:00 am

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

US-Aust Colloquium. Superconductors and semiconductors, nanowires and majorana, research and integrity

We're sorry, but all tickets sales have ended because the event is expired.

24 Aug 2022
10:00 am - 11:00 am

Sergey Frolov, University of Pittsburgh Watch on YouTube This talk will be on three topics, but in a way it is one. My research focus and passion is the proximity effect. It is when superconducting correlations are induced in a non-superconducting material. Because superconductivity is always tied to a spin order, proximity effects get especially Read More

Making metal stuff fly, levitation and the potential of superconductors

What follows is in answer to a question about whether we could make metal object fly without any help from engine-like things. If you live on Earth or anywhere that gravity exists, and you have mass (that is, you are made up of atoms and have weight), then gravity will always want to pull you toward the Earth. Actually, anything ...

Shapes and Patterns & the next big thing in physics: moiré pattern and twistronics

What can you do with simple shapes? Create a type of animation that will surprise you. It is cool quantum art, yet our understanding of moiré patterns is behind the development of novel materials to enable quantum computing, and to develop energy-efficient digital technologies, data storage and information and electricity transmission. It all comes down to magic angles and what ...
