Influence of Dynamical Floquet Spectrum on the Plasmon Excitations and Exchange Energy of tilted monolayer 1TMoS
Sita Kandel, Godfrey Gumbs, Antonios Balassis +2
It is now well established that a high-frequency electromagnetic dressing field within the off-resonance regime significantly modifies the electronic transport and optical properti…
Polarizability, plasmons, and screening in 1T-MoS with tilted Dirac bands
Antonios Balassis, Godfrey Gumbs, Oleksiy Roslyak
In the presence of an external vertical electric field and strain, it is evident that 1T-MoS exhibits tilted Dirac bands which are valley-spin-polarized. Additionall…
Second-harmonic generation in nonlinear plasmonic lattices enhanced by quantum emitter gain medium
Maxim Sukharev, Oleksiy Roslyak, Andrei Piryatinski
We report on theoretical study of second-harmonic generation (SHG) in plasmonic nanostructures interacting with two-level quantum emitters (QE) under incoherent energy pump. We gen…
Effect of magnetic field and chemical potential on the RKKY interaction in the - lattice
Oleksiy Roslyak, Godfrey Gumbs, Antonios Balassis +1
The interaction energy for the indirect-exchange or Ruderman-Kittel-Kasuva-Yosida (RKKY) interaction between magnetic spins localized on lattice sites of the - model…
Liquid crystal nose based on chiral photonic band gap materials: principles of selective response
P. V. Shibaev, O. Roslyak, E. Gullatt +2
Novel liquid crystalline (LC) compositions are suggested and studied as elements of LC-nose. This allows for optical detection of several volatile organic compounds (VOCs). Ethanol…
Non-equilibrium states of a plasmonic Dicke model with coherent and dissipative surface plasmon-quantum emitter interactions
Andrei Piryatinski, Oleksiy Roslyak, Hao Li +1
Hybrid photonic-plasmonic nanostructures allow one to engineer coupling of quantum emitters and cavity modes accounting for the direct coherent and environment mediated dissipative…
