Geometric phase and o-mode blueshift in a chiral anisotropic medium inside a Fabry-Pérot cavity
Anomalous spectral shift of transmission peaks is observed in a Fabry-P´ erot cavity filled with a chiral anisotropic medium. The effective refractive index value resides out of the interval between the ordinary and the ...
Quantum phase transitions in two-dimensional tilted optical lattices
We discuss the quantum phase transition between the Mott-insulator state and the density-wave state of cold Bose atoms in a two-dimensional (2D) square lattice as the lattice is adiabatically tilted along one of its primary ...
The optical Tamm states at the edges of a photonic crystal bounded by one or two layers of a strongly anisotropic nanocomposite
The optical Tamm states localized at the edges of a photonic crystal bounded by a nanocomposite on its one or both sides are investigated. The nanocomposite consists of metal nanoinclusions with an or- ientation-ordered ...
Spectral and polarization properties of a ‘cholesteric liquid crystal—phase plate—metal’ structure
We investigate the localized surface modes in a structure consisting of the cholesteric liquid crystal layer, a phase plate, and a metal layer. These modes are analogous to the optical Tamm states. The nonreciprocal ...
Localised optical states in a structure formed by two oppositely handed cholesteric liquid crystal layers and a metal
A new model for observing localised optical states in a structure containing a cholesteric liquid crystal is proposed. The dependence of the mode frequency on the angle between directors at the interface of oppositely ...
Chiral optical Tamm states at the boundary of the medium with helical symmetry of the dielectric tensor
A new optical state is described both analytically and numerically at the boundary of a chiral medium with continuous helical symmetry of the dielectric tensor. The tangential wave number is assumed to be zero. The state ...
