A novel undamped gapless plasmon mode in tilted type-II Dirac semimetal
Krishanu Sadhukhan, Antonio Politano, Amit Agarwal
We predict the existence of a novel long-lived gapless plasmon mode in a type-II Dirac semimetal (DSM). This gapless mode arises from the out-of-phase oscillations of the density f…

Dynamic current-current susceptibility in 3D Dirac and Weyl semimetals
Anmol Thakur, Krishanu Sadhukhan, Amit Agarwal
We study the linear response of doped three dimensional Dirac and Weyl semimetals to vector potentials, by calculating the wave-vector and frequency dependent current-current respo…
