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…

Calculation of Gilbert damping and magnetic moment of inertia using torque-torque correlation model within ab initio Wannier framework
Robin Bajaj, Seung-Cheol Lee, H. R. Krishnamurthy +2
Magnetization dynamics in magnetic materials are well described by the modified semiclassical Landau-Lifshitz-Gilbert (LLG) equation, which includes the magnetic damping and th…
