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…
Curvature function renormalisation, topological phase transitions and multicriticality
Faruk Abdulla, Priyanka Mohan, Sumathi Rao
A recently proposed curvature renormalization group scheme for topological phase transitions defines a generic `curvature function' as a function of the parameters of the theory an…
Tailoring Metal Insulator Transitions Band Topology via Off-resonant Periodic Drive in an Interacting Triangular Lattice
Sayan Jana, Priyanka Mohan, Arijit Saha +1
A triangular lattice with onsite Coulomb interaction present only on one sub-lattice, is periodically driven by electromagnetic field with a frequency at half fil…
Interplay of Floquet Lifshitz transitions and topological transitions in bilayer Dirac materials
Priyanka Mohan, Sumathi Rao
We show how transitions between different Lifshitz phases in bilayer Dirac materials with and without spin-orbit coupling can be studied by driving the system. The periodic driving…
Low-frequency phase diagram of irradiated graphene and periodically driven spin-1/2 chain
Bhaskar Mukherjee, Priyanka Mohan, Diptiman Sen +1
We study the Floquet phase diagram of two-dimensional Dirac materials such as graphene and the one-dimensional (1D) spin-1/2 model in a transverse field in the presence of per…
Slave fermion formalism for the tetrahedral spin chain
Priyanka Mohan, Sumathi Rao
We use the SU(2) slave fermion approach to study a tetrahedral spin 1/2 chain, which is a one-dimensional generalization of the two dimensional Kitaev honeycomb model. Using the me…
