Resonant scattering of Dice quasiparticles on oscillating quantum dots
Alexander Filusch, Christian Wurl, Holger Fehske
We consider a Dice model with Dirac cones intersected by a topologically flat band at the charge neutrality point and analyze the inelastic scattering of massless pseudospin-1 part…

Time-periodic Klein tunneling through optomechanical Dirac barriers
Christian Wurl, Holger Fehske
We study the interconversion between photons and phonons coupled via radiation pressure in artificial Dirac materials realized by a honeycomb array of optomechanical cells. In part…

Light-sound interconversion in optomechanical Dirac materials
Christian Wurl, Holger Fehske
Analyzing the scattering and conversion process between photons and phonons coupled via radiation pressure in a circular quantum dot on a honeycomb array of optomechanical cells, w…
