Emergent fractals in hBN-encapsulated graphene based supermoiré structures and their experimental signatures
Deepanshu Aggarwal, Rohit Narula, Sankalpa Ghosh
Supermoiré structures (SMS), formed by overlapping moiré-patterns in van der Waals heterostructures, display complex behaviour that lacks a comprehensive low-energy theoretical des…
Photon absorption in twisted bilayer graphene
Disha Arora, Deepanshu Aggarwal, Sankalpa Ghosh +1
We investigate one- and two-photon absorption in twisted bilayer graphene (TBLG) by examining the effects of tuning the twist angle and the excitation energy on its ab…
Moiré fractals in twisted graphene layers
Deepanshu Aggarwal, Rohit Narula, Sankalpa Ghosh
Twisted bilayer graphene (TBLG) subject to a sequence of commensurate external periodic potentials reveals the formation of moiré fractals (MF) that share striking similarities wit…
Revisiting Andreev processes in superconductor-graphene-superconductor (SGS) Josephson junctions: Comparison with experimental results
Shahrukh Salim, Rahul Marathe, Sankalpa Ghosh
In view of the recent progress in experiments on charge transport through various Josephson junctions made out of graphene, we have made a careful comparison between the theory and…
Interference effects in polarization controlled Rayleigh scattering in twisted bilayer graphene
Disha Arora, Deepanshu Aggarwal, Sankalpa Ghosh +1
We calculate the \tco{polarization}-controlled Rayleigh scattering response of twisted bilayer graphene (tBLG) based on the continuum electronic band model developed by Bistritzer…
A primer on twistronics: A massless Dirac fermion's journey to moiré patterns and flat bands in twisted bilayer graphene
Deepanshu Aggarwal, Rohit Narula, Sankalpa Ghosh
The recent discovery of superconductivity in magic-angle twisted bilayer graphene has sparked a renewed interest in the strongly-correlated physics of carbons, in stark cont…
