Mini workshop “Towards strong correlations in van der Waals heterostructures and 2D materials”

25 March 2021, from 13h55 to 18h00 CET

The workshop will start at 13h55 central European time. Please keep in mind that some countries switched to daylight saving time and some did not. Thus, time difference between different time zones might be different than usual.

Organizers: Yonathan Anahory and Milorad Milosevic.

Aims and scope

The COST Action nanocohybri develops ground breaking research in superconducting hybrid nanostructures. Recent experimental breakthroughs in building nanostructures out of 2D materials have lead to the observation of correlated insulating and superconducting states in structures with twisted layers, particularly in bilayer graphene. This provides a new opportunity to harness strong correlations and study its influence on superconductivity, which might impact our understanding of electron correlation driven high-temperature superconductivity. This workshop aims to gather Action participants with world-wide experts to address the overarching open questions, regarding both theory and experiment, in the establishment and characterization of strong correlations in hybrid nanostructures.

This miniworkshop is part of a series which will be organized within an agile format, consisting of virtual half-a-day mini-workshops on a thriving new research results in the field of the Action. There will be three 25+5’ talks and several 15+5’ talks, by invitation after consultation to the COST MC. Poster sessions will be also organized on demand. We particularly welcome the participation of young students and follow excellence and inclusiveness strategy of COST.

Every participant will receive a certificate upon request by writing to
