Universality in quantum critical flow of charge and heat in ultra-clean graphene
Aniket Majumdar, Nisarg Chadha, Pritam Pal +6
Close to the Dirac point, graphene is expected to exist in quantum critical Dirac fluid state, where the flow of both charge and heat can be described with a dc electrical conducti…
Spin-orbit coupling-enhanced valley ordering of malleable bands in twisted bilayer graphene on WSe2
Saisab Bhowmik, Bhaskar Ghawri, Youngju Park +8
New phases of matter can be stabilized by a combination of diverging electronic density of states, strong interactions, and spin-orbit coupling. Recent experiments in magic-angle t…
Quantum Hall interferometry in triangular domains of marginally twisted bilayer graphene
Phanibhusan S. Mahapatra, Manjari Garg, Bhaskar Ghawri +5
Quantum Hall (QH) interferometry provides an archetypal platform for the experimental realization of braiding statistics of fractional QH states. However, the complexity of observi…
Emergence of broken-symmetry states at half-integer band fillings in twisted bilayer graphene
Saisab Bhowmik, Bhaskar Ghawri, Nicolas Leconte +9
The dominance of Coulomb interactions over kinetic energy of electrons in narrow, non-trivial moiré bands of magic-angle twisted bilayer graphene (TBG) gives rise to a variety of c…
Excess entropy and breakdown of semiclassical description of thermoelectricity in twisted bilayer graphene close to half filling
Bhaskar Ghawri, Phanibhusan S. Mahapatra, Shinjan Mandal +9
In moiré systems with twisted bilayer graphene (tBLG), the amplification of Coulomb correlation effects at low twist angles () is a result of nearly flat low-energy electronic b…
Evidence of Lifshitz transition in thermoelectric power of ultrahigh mobility bilayer graphene
Aditya Jayaraman, Kimberly Hsieh, Bhaskar Ghawri +2
Resolving low-energy features in the density of states (DOS) holds the key to understanding wide variety of rich novel phenomena in graphene based 2D heterostructures. Lifshitz tra…
Mis-orientation controlled cross-plane thermoelectricity in twisted bilayer graphene
Phanibhusan S Mahapatra, Bhaskar Ghawri, Kenji Watanabe +3
The introduction of 'twist' or relative rotation between two atomically thin van der Waals (vdW) membranes gives rise to periodic Moire potential, leading to a substantial altercat…
