Band structure evolution from kagome to Lieb under periodic driving field
Gulshan Kumar, Shashikant Kumar, Prakash Parida
We theoretically investigate the light-induced transition of the kagome quasienergy spectrum to the Lieb like band structure under periodic driving fields. A generalized framework…

Engineering two-dimensional kagome topological insulator from porous graphene
Shashikant Kumar, Gulshan Kumar, Ajay Kumar +1
Our study sets forth a carbon based two-dimensional (2D) kagome topological insulator without containing any metal atoms, that aligns the Fermi level with the Dirac point without t…

Predicting edge-localized monovacancy defects in zigzag graphene nanoribbons from Floquet quasienergy spectrum
Gulshan Kumar, Shashikant Kumar, Ajay Kumar +1
In this work, we prescribe a theoretical framework aiming at predicting the position of monovacancy defects at the edges of zigzag graphene nanoribbons (ZGNRs) using Floquet-Bloch…
