Trigonal Warping, Satellite Dirac Points and Multiple Field Tuned Topological Transitions in Twisted Double Bilayer Graphene
Priyanka Mohan, Unmesh Ghorai, Rajdeep Sensarma
We show that the valley Chern number of the low energy band in twisted double bilayer graphene can be tuned through two successive topological transitions, where the direct bandgap…

Tunable bandwidths and gaps in twisted double bilayer graphene system on the verge of correlations
Pratap Chandra Adak, Subhajit Sinha, Unmesh Ghorai +5
We use temperature-dependent resistivity in small-angle twisted double bilayer graphene to measure bandwidths and gaps of the bands. This electron-hole asymmetric system has one se…
