Kohn anomaly in a topological phase transition
Jingwen Li, Arpita Dutta, Kush Saha +4
Topological crystalline insulators extend the concept of topological insulators by hosting surface states protected by crystallographic symmetry. Their topological phase transition…
Non-trivial phonon dynamics and significant electron-phonon coupling of the high frequency modes in a Dirac semimetal
Debasmita Swain, Akash Dey, Anushree Roy +2
Using finite temperature Raman spectroscopy, we investigate the electron-phonon interactions (EPI) and phonon-phonon scattering dynamics in the Dirac semimetal Cd3As2 in different…
Thermoelectric response in nodal-point semimetals
Ipsita Mandal, Kush Saha
In this review, the thermoelectric properties in nodal-point semimetals with two bands are discussed. For the two-dimensional (2D) cases, it is shown that the expressions of the th…
Current-induced spin polarisation in Rashba-Dresselhaus systems under different point groups
Akash Dey, Ashis K. Nandy, Kush Saha
Non-magnetic materials without inversion symmetry typically exhibit strong Rashba spin-orbit coupling (SOC), enabling the well-known Rashba Edelstein effect where an external elect…
