Bulk contributions to the Casimir interaction of Dirac materials
M. Bordag, I. Fialkovsky, N. Khusnutdinov +1
Exploiting methods of Quantum Field Theory we compute the bulk polarization tensor and bulk dielectric functions for Dirac materials in the presence of a mass gap, chemical potenti…
Casimir interaction of strained graphene
M. Bordag, I. Fialkovsky, D. Vassilevich
We calculate the Casimir interaction of two freestanding graphene samples under uniaxial strain. Our approach fully takes retardation and dispersion into account and is based on qu…
Surface plasmon on graphene at finite
M. Bordag, I. Pirozhenko
Using the recently developed polarization tensor in (2+1) dimensions for the electronic excitations of graphene, we investigate the influence of temperature on the surface plasmons…
Enhanced Casimir effect for doped graphene
M. Bordag, I. Fialkovsky, D. Vassilevich
We analyze the Casimir interaction of doped graphene. To this end we derive a simple expression for the finite temperature polarization tensor with a chemical potential. It is foun…
Surface plasmons for doped graphene
M. Bordag, I. G. Pirozhenko
Within the Dirac model for the electronic excitations of graphene, we calculate the full polarization tensor with finite mass and chemical potential. It has, besides the (00)-compo…
Quantum field theoretical description for the reflectivity of graphene
M. Bordag, G. L. Klimchitskaya, V. M. Mostepanenko +1
We derive the polarization tensor of graphene at nonzero temperature in (2+1)-dimensional space-time. The obtained tensor coincides with the previously known one at all Matsubara f…
