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…
