Excitonic Metal and Non-Fermi Liquid Behaviour in Twisted Double Bilayer Graphene near Charge Neutrality
Unmesh Ghorai, Ayan Ghosh, Anindya Das +1
Twisted double bilayer graphene is a compensated semi-metal near the charge neutrality point with the presence of small electron and hole pockets in its band structure. We show tha…
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…
Interaction driven giant thermopower in magic-angle twisted bilayer graphene
Arup Kumar Paul, Ayan Ghosh, Souvik Chakraborty +9
Magic-angle twisted bilayer graphene (MtBLG) has proven to be an extremely promising new platform to realize and study a host of emergent quantum phases arising from the strong cor…
Generating Subgroups of the Circle using a Generalized class of Density Functions
Pratulananda Das, Ayan Ghosh
In this article, we consider the generalized version of the natural density function introduced in \cite{BDK} where satisfies $g(n) \rightar…
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…
