Coulomb-induced synchronization of intersubband coherences in highly doped quantum wells and the formation of giant collective resonances
Mikhail Tokman, Maria Erukhimova, Yongrui Wang +1
Many-body Coulomb interactions drastically modify the optical response of highly doped semiconductor quantum wells leading to a merger of all intersubband transition resonances int…
Relaxation operator for quasiparticles in a solid
Maria Erukhimova, Yongrui Wang, Mikhail Tokman +1
Popular models of the phenomenological relaxation operators that are widely used in the master equation formalism for open condensed-matter systems have significant flaws ranging f…
Four-wave mixing in Weyl semimetals
Sultan Almutairi, Qianfan Chen, Mikhail Tokman +1
Weyl semimetals (WSMs) have unusual optical response originated from unique topological properties of their bulk and surface electron states. Their third-order optical nonlinearity…
Inverse Faraday effect in graphene and Weyl semimetals
I. D. Tokman, Qianfan Chen, I. A. Shereshevsky +4
We report systematic theoretical studies of the inverse Faraday effect in materials with massless Dirac fermions, both in two dimensions such as graphene and surface states in topo…
Extreme anisotropy and gyrotropy of surface polaritons in Weyl semimetals
Qianfan Chen, Maria Erukhimova, Mikhail Tokman +1
Weyl semimetals possess unique electrodynamic properties due to a combination of strongly anisotropic and gyrotropic bulk conductivity, surface conductivity, and surface dipole lay…
Second harmonic generation in graphene dressed by a strong terahertz field
Mikhail Tokman, Sergei B. Bodrov, Yuri A. Sergeev +5
We observe enhanced second-harmonic generation in monolayer graphene in the presence of an ultra-strong terahertz field pulse with a peak amplitude of 250 kV/cm. This is a strongly…
