Evidence of a compensated semimetal with electronic correlations at the CNP of twisted double bilayer graphene
Ayan Ghosh, Souvik Chakraborty, Unmesh Ghorai +5
Recently, magic-angle twisted bilayer graphene (MATBLG) has shown the emergence of various interaction-driven novel quantum phases at the commensurate fillings of the moir'e superl…

Topological torsion elements via natural density and a quest for solution of Armacost like problem
Pratulananda Das, Ayan Ghosh
One can use the number theoretic idea of the notion of natural density \cite{B1} to define topological s-torsion elements (which form the statistically characterized subgroups, rec…
