Asymmetric spatial structure of zero modes for birefringent Dirac fermions
Bitan Roy, Peter M. Smith, Malcolm P. Kennett
We study the zero energy modes that arise in an unusual vortex configuration involving both the kinetic energy and an appropriate mass term in a model which exhibits birefringent D…

Multi-critical behavior of Gross-Neveu-Yukawa theory in graphene
Bitan Roy
Multi-critical behavior of interacting fermions in graphene's honeycomb lattice is presented. In particular, we considered the spin triplet insulating orders, where the spin rotati…
