Angstrom-Scale Active Width Control of Nano Slits for Variable Plasmonic Cavity

Nanomaterials, 2021
Nanogap slits can operate as a plasmonic Fabry–Perot cavity in the visible and infrared ranges due to the gap plasmon with an increased wavenumber. Although the properties of gap plasmon are highly dependent on the gap width, active width tuning of the ...

Gravitoelectromagnetism in a complex Clifford algebra

, 2005
A linear vector model of gravitation is introduced in the context of quantum physics as a generalization of electromagnetism. The gravitoelectromagnetic gauge symmetry corresponds to a hyperbolic unitary extension of the usual complex phase symmetry of ...
