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…
Electrically switchable tunneling across a graphene pn junction: evidence for canted antiferromagnetic phase in state
Arup Kumar Paul, Manas Ranjan Sahu, Kenji Watanabe +4
The ground state of a graphene sheet at charge neutrality in a perpendicular magnetic field remains enigmatic, with various experiments supporting canted antiferromagnetic, bond or…
Determination of topological edge quantum numbers of fractional quantum Hall phases
Saurabh Kumar Srivastav, Ravi Kumar, Christian Spånslätt +5
To determine the topological quantum numbers of fractional quantum Hall (FQH) states hosting counter-propagating (CP) downstream () and upstream () edge modes, it is pivo…
Effect of boron nitride defects and charge inhomogeneity on 1/f noise in encapsulated graphene
Chandan Kumar, Anindya Das
Low frequency 1/f noise is investigated in graphene, encapsulated between hexagonal boron nitride (hBN) substrate in dual gated geometry. The overall noise magnitude is smaller as…
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…
