Strain- and doping-tunable optical resonance in Kekulé-Y graphene
Yawar Mohammadi
We investigate the optical response of Kekulé-Y graphene under uniaxial strain and carrier doping. Using a low-energy effective Hamiltonian, we show that strain reshapes the low-en…

Optical fingerprints across the strain-driven semi-Dirac transition in Kekulé-O graphene
Yawar Mohammadi
We show that the strain-driven semi-Dirac transition in Kekulé-O graphene gives rise to a sequence of anisotropic optical fingerprints associated with band structure reconstruction…

Integer quantum Hall effect in AAA-stacked trilayer graphene
Yawar Mohammadi
We obtain an analytical expression for the Hall conductivity in AAA-stacked trilayer graphene (TLG) within the linear response Kubo formalism. Interestingly, we find that the quant…
