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 (…
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…
Superconductivity in doped planar Dirac insulators: A renormalization group study
Sk Asrap Murshed, Sanjib Kumar Das, Bitan Roy
From a leading-order unbiased renormalization group analysis we here showcase the emergence of superconductivity (including the topological ones) from purely repulsive electron-ele…
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…
Quantum Electrodynamics of Non-Hermitian Dirac Fermions
Sk Asrap Murshed, Bitan Roy
We develop an effective quantum electrodynamics for non-Hermitian (NH) Dirac materials interacting with photons. These systems are described by nonspatial symmetry protected Lorent…
Nodal pair density waves from a quarter-metal in crystalline graphene multilayers
Sk Asrap Murshed, Bitan Roy
Crystalline graphene heterostructures, namely, Bernal bilayer graphene (BBLG) and rhombohedral trilayer graphene (RTLG), for example, subject to perpendicular electric displacement…
