Electron-phonon interactions and tensor analysis in topological insulator bismuth telluride using angle resolved polarized Raman spectroscopy
Aditya Singh, Anna Elsukova, Divya Rawat +6
We report on the angle-resolved polarized Raman spectroscopy and estimation of the Raman tensor elements using both classical and quantum treatments to analyse the polarized Raman…

Emergence of spin-phonon coupling in a Gd-doped YCoMnO double perovskite oxide: a combined experimental and ab-initio study
Anasua Khan, Debdatta Banerjee, Divya Rawat +4
We present Raman spectroscopy results backed by first-principles calculations and investigate the nature of possible spin-phonon coupling (SPC) in a Gd-doped YCoMnO (YGCMO)…

Multiphonon interactions and collective excitations in charge density wave of transition metal dichalcogenides
Divya Rawat, Juhi Pandey, Ajay Soni
Charge density wave (CDW) is a periodic modulation of electronic charge leading to a reconstruction of the lattice, an emergence of zone folded mode along with collective excitatio…
