Magnon transmission across mono-layer graphene junction as a probe of electronic structure
Suman Jyoti De, Sumathi Rao, Ganpathy Murthy
We study magnon transmission across gate-controlled junctions in the manifold of Landau levels in monolayer graphene, in the presence of both spin and valley Zeeman fields. S…

Brillouin-Wigner Theory for Floquet Topological Phase Transitions in Spin-orbit Coupled Materials
Priyanka Mohan, Ruchi Saxena, Arijit Kundu +1
We develop the high frequency expansion based on the Brillouin-Wigner (B-W) perturbation theory for driven systems with spin-orbit coupling which is applicable to the cases of sili…

A Bosonic Mean-Field Theory for Frustrated Heisenberg Antiferromagnets in Two Dimensions
R. Chitra, Sumathi Rao, Diptiman Sen
We use a recently developed bosonic mean-field theory (MFT) to study the ordered ground states of frustrated Heisenberg antiferromagnets (FHAFM) in two dimensions. We emphasize the…
