Radiative corrections arising from Lorentz violation in the fermion sector induce a nonzero amplitude for vacuum photon splitting. At one loop, the on-shell amplitude acquires both CPT-even and CPT-odd contributions forbidden in conventional electrodynamics.

We discuss the polarization selection rules for splitting of the two principal electromagnetic modes that propagate in a vacuum polarized by a superstrong magnetic field (B > 0.1Bcr ' 4 × 10 G). We show that below the threshold of free pair creation the selection rules found by Adler in the limit of weak dispersion remain unaffected by taking the resonant effects into consideration, i.e., split...

The ζ function of a massive scalar field near a cosmic string is computed and then employed to find the vacuum fluctuation of the field. The vacuum expectation value of the energy-momentum tensor is also computed using a point-splitting approach. The obtained results could be useful also for the case of self-interacting scalar fields and for the finite-temperature Rindler space theory. PACS num...

Interaction of cavity modes with an exciton in a meso-cavity (the structure supporting several separated by energy interval comparable to Rabi-splitting and modes) has been analyzed using quantum-mechanical approach. Simultaneous interaction results few novel effects such as ladder-like increase the population system, quantum beating non-monotonic dependence ground polariton state system on pum...

A laser model is formulated in terms of quantum harmonic oscillators. Emitters the low lasing states are usual oscillators, and emitters upper inverted Diffusion coefficients, consistent with necessary for solving nonlinear equations analytically, found. Photon number fluctuations mode population calculated. Collective Rabi splitting peaks predicted intensity fluctuation spectra superradiant la...

Abstract Modifying the light–matter interactions in plasmonic structures and two-dimensional (2D) materials not only advances deeper understanding of fundamental studies many-body physics but also provides opportunities for exploration novel 2D polaritonic devices. Here, we report plasmon-exciton coupling hybrid system with a metasurface which can confine electric field an extremely compact mod...

Optical nanocavity provides an opportunity to deeply study the light–matter interaction with notable findings such as Rabi splitting in strong coupling and Fano resonance weak coupling. Here, we theocratically explore plexcitons of a bilayer (BL) borophene synthesized on Ag (1 1 1) film tip-enhanced Raman scattering (TERS) system, where BL is located between tip substrate, stimulated by recent ...
