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…
Emergent Rashba spin-orbit coupling in bulk gold with buried network of nanoscale interfaces
Shreya Kumbhakar, Banashree Debnath, Tuhin Kumar Maji +8
The Rashba effect, which plays a crucial role in fundamental materials physics and potential spintronics applications, has been engineered in diverse systems, including semiconduct…
Double excitations in molecules
Namana Venkatareddy, Victor Ghosh, H. R. Krishnamurthy +1
Double excitations in organic molecules have garnered significant interest as a result of their importance in singlet fission and photophysics. These excitations play a crucial rol…
PARPHOM: PARallel PHOnon calculator for Moiré systems
Shinjan Mandal, Indrajit Maity, H R Krishnamurthy +1
The introduction of a twist between two layers of two-dimensional materials has opened up a new and exciting field of research known as twistronics. In these systems, the phonon di…
