Recent experimental observations have shown that twisted transition metal dichalcogenides (TMDs) may host correlated phases which develop in presence of a Moiré superlattice [1,2]. Coupling to this long-wavelength periodic potential results in the formation of weakly...

One of the most fascinating phenomena in two-dimensional quantum systems is the formation of topological order and the implied emergence of anyonic quasiparticles. Anyons have neither bosonic nor fermionic character, but their wave function can acquire an arbitrary...

Since the discovery of high-temperature superconductivity in cuprates, Josephson junction based phase-sensitive experiments are believed and used to provide the most convincing evidence for determining the pairing symmetry. Regardless of different junction materials...

From LAO/STO interfaces, monolayer FeSe, MoS$_2$, exfoliated graphene or cuprates: in recent years the ubiquity of two-dimensional superconductors has grown exponentially. At this first Flat Club meeting of the fall 2021, I will review the distinguishing features of...

Abrikosov vortices hosting robust and well isolated zero-energy bound states have been recently found in FeTe$_{0.55}$Se$_{0.45}$, as reported by several different STM groups [1-3]. These vortices attract attention as the possible building blocks in a scenario of...
