Kaganov-Lifshitz-Tanatarov theory for tilted Dirac-cone materials: anisotropic heating from uniform light
Navinder Singh Bathinda, Bharathiganesh Devanarayanan, Sruthi Sudhakaran +2
We point out that in the tilted Dirac cone materials the non-equilibrium (hot) electron relaxation with phonons is anisotropic in the Brillouin zone. It means that there is a prefe…
New plasmon-like mode in PdTe: Raman scattering and memory function study
Bharathiganesh Devanarayanan, Sahil Rathi, Jalaja Pandya +4
PdTe is a type II Dirac semimetal that has garnered significant attention due to its intriguing electronic and topological properties. Here, we report temperature dependent Ram…
DFT Investigations of Major Defects in Quartz Crystal: Implications for Luminescence and ESR Dosimetry and Dating
Jalaja Pandya, Malika Singhal, Navinder Singh Bathinda +1
Quartz is extensively used for luminescence and ESR dosimetry as well as dating. These techniques use inherent defects introduced in quartz crystal during its crystallization in na…
Unifying principle for Hall coefficient in systems near magnetic instability
Jalaja Pandya, Navinder Singh Bathinda
Typically, Hall coefficient of materials near magnetic instabilities exhibits pronounced temperature dependence. To explore the reasons involved, we studied the temperature depende…
Pseudogap in \(Sr_{2-x}La_{x}IrO_{4}\): Gor'kov-Teitel'baum thermal activation model
Jalaja Pandya, Devarshi Dave, Navinder Singh Bathinda
Recently, Hall effect measurements are done on Lanthanum doped Strontium Iridate \(Sr_{2-x}La_{x}IrO_{4}\) which is 5d analogue of cuprates \cite{hsu2023carrier}. Hall effect measu…
