Photon Momentum Enabled Symmetry Breaking and Nonlinear Photocurrents in the Centrosymmetric Dirac Semimetal PdTe
Sambhu G Nath, Subhadip Manna, R K Gopal +1
In centrosymmetric Dirac semimetals, second order nonlinear photocurrents are forbidden by the coexistence of time-reversal and inversion symmetries. Here, we demonstrate that fini…
Magnetoconductance evolution across the topological-trivial phase transition in thin films
Sambhu G Nath, Subhadip Manna, Kanav Sharma +4
We investigate the evolution of electronic transport across the topological-trivial phase transition in thin films by s…
