Symmetries in zero and finite center-of-mass momenta excitons
Robin Bajaj, Namana Venkatareddy, H. R. Krishnamurthy +1
We present a symmetry-based framework for the analysis of excitonic states, incorporating both time-reversal and space-group symmetries. We demonstrate the use of time-reversal and…

Atomic relaxation and flat bands in strain-engineered transition metal dichalcogenide bilayer moiré systems
Sudipta Kundu, Indrajit Maity, Robin Bajaj +2
Strain-induced lattice mismatch leads to moiré patterns in homobilayer transition metal dichalcogenides (TMDs). We investigate the structural and electronic properties of such str…
