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…
Spontaneous time reversal symmetry breaking at individual grain boundaries in graphene
Kimberly Hsieh, Vidya Kochat, Tathagata Biswas +8
Graphene grain boundaries have attracted interest for their ability to host nearly dispersionless electronic bands and magnetic instabilities. Here, we employ quantum transport and…
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…
Optimising Graphene Visibility in van der Waals Heterostructures
Thanmay S. Menon, Simli Mishra, Vidhu Catherine Antony +8
Graphene constitutes one of the key elements in many functional van der Waals heterostructures. However, it has negligible optical visibility due to its monolayer nature. Here we s…
Marginally Self-Averaging One-Dimensional Localization in Bilayer Graphene
Md. Ali Aamir, Paritosh Karnatak, Aditya Jayaraman +4
The combination of field tunable bandgap, topological edge states, and valleys in the band structure, makes insulating bilayer graphene a unique localized system, where the scaling…
