Pair density wave in quarter metals from a repulsive fermionic interaction in graphene heterostructures: A renormalization group study
Sk Asrap Murshed, Bitan Roy
Electronic bands in chirally stacked layer carbon-based honeycomb heterostructures, encompassing rhombohedral or ABC (), Bernal or AB bilayer (), and monolayer (…
Global phase diagram of two-dimensional dirty hyperbolic Dirac liquids
Christopher A. Leong, Daniel J. Salib, Bitan Roy
Within the framework of the canonical nearest-neighbor tight-binding model for spinless fermions, a family of two-dimensional bipartite hyperbolic lattices hosts massless Diraclike…
Strained hyperbolic Dirac fermions: Zero modes, flat bands, and competing orders
Christopher A. Leong, Bitan Roy
Starting from the nearest-neighbor tight-binding model on {10,3} and {14,3} hyperbolic lattices that, for a uniform hopping amplitude, gives rise to emergent Dirac fermions on a cu…
Amplified magnetic catalysis in non-Hermitian Euclidean and hyperbolic Dirac liquids
Christopher A. Leong, Bitan Roy
Due to their iconic linearly vanishing density of states near the zero-energy, half-filled two-dimensional Dirac materials in flat Euclidean and negatively-curved hyperbolic spaces…
Charge density waves and stripes in quarter metals of graphene heterostructures
Sk Asrap Murshed, Bitan Roy
Motivated by recent experiments, here we identify valley-coherent charge density wave (VC-CDW) in the nondegenerate quarter metal for the entire family of chirally-stacked laye…
Zero modes and index theorems for non-Hermitian Dirac fermions
Bitan Roy
Dirac fermions, subject to external magnetic fields and in the presence of mass orders that assume topologically nontrivial spatial textures such as domain wall and vortices, for e…
Non-Hermitian catalysis of spontaneous symmetry breaking on Euclidean and hyperbolic lattices
Christopher A. Leong, Bitan Roy
Depending on the lattice geometry, the nearest-neighbor (NN) tight-binding model for free fermions gives rise to particle-hole symmetric emergent Dirac liquid, Fermi liquid, and fl…
