The Hat tiling, discovered in March this year, is the culmination of decades of mathematical research in aperiodic tilings. Unlike other quasicrystals, such as the Penrose tiling, it requires only a single type of tile to be assembled, the hat tile. In this talk I...

Flat bands in twisted graphene systems offers plethora of strongly correlated states, among these, correlated insulator, superconductor and chern insulator are to name of few. Twisted trilayer graphene has shown robust superconductivity which drastically deviates from...

Dense amorphous materials which exhibits a solid-like behaviour, or ‘structural glasses’, are ubiquitous around us. They span a very wide range of experimental systems in soft matter, condensed matter, or biophysics, such as emulsions, foams, biological tissues,...

I will talk about types and properties of excitons in two-dimensional (2D) van der Waals magnetic insulators and semiconductors, such as CrI3, CrSBr, NiPS3, etc. In these materials excitons couple with the spin-polarized band structure, resulting in various correlated...

The study of strongly interacting electrons in moiré heterostructures of semiconducting transition metal dichalcogenides (sTMDs), such as WSe2 and WS2, has led to the discovery of long sought-after quantum phases and behavior. In addition, strong light-matter...
