Tight-binding and density-functional study of the Raman tensor in two-dimensional massive Dirac fermion systems
Selçuk Parlak, Abhishek Kumar, Runhan Li +2
Recently, two unusual features were theoretically predicted for the Raman response of out-of-plane phonons in magnetic two-dimensional materials hosting massive Dirac fermions. Fir…

Inherited Berry curvature of phonons in Dirac materials with time-reversal symmetry
Sayandip Ghosh, Selçuk Parlak, Ion Garate
The Berry curvature of phonons is an active subject of research in condensed matter physics. Here, we present a model in which phonons acquire a Berry curvature through their coupl…
