Hidden-ordered Dirac fermions
Bitan Roy
I propose a Hermitian extension of the Lorentz-symmetric Dirac theory by complementing the associated Hamiltonian with another \emph{masslike} anticommuting Dirac operator. The res…
Anisotropic marginal Fermi liquid for Coulomb interacting generalized Weyl fermions
Gabriel Malavé, Rodrigo Soto-Garrido, Bitan Roy +1
Owing to the power-law anisotropy in the quasiparticle dispersion, yielding an enhanced density of states, the effects of long range Coulomb interaction get amplified in three-dime…
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…
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…
Yukawa-Lorentz symmetry of interacting non-Hermitian birefringent Dirac fermions
Sk Asrap Murshed, Bitan Roy
The energy spectra of linearly dispersing gapless spin-3/2 Dirac fermions display birefringence, featuring two effective Fermi velocities, thus breaking the space-time Lorentz symm…
