Abstract: Abstract In standard quantum theory, the Hamiltonian describing a physical system is assumed to be Hermitian in order to guarantee the energy spectrum to be real and the time evolution to be unitary. In recent… read more here.

Abstract: A coherent atomic medium is proposed for manipulating the absorption, dispersion, transmission and reflection of an optical soliton via two strong coherent control field’s Rabi oscillations, detunings and incident angles. Significant anomalous dispersion regions and… read more here.

Abstract: Spatial distribution of atoms plays an important role in the interaction of atomic ensembles and electromagnetic fields. In this Letter, we show that by spatio-spectral tailoring of atomic absorption, one can effectively carve out a… read more here.

DOI: 10.3390/sym14061135
Abstract: We propose a scheme to realize a parity-time (PT) symmetric nonlinear system in a coherent atomic gas via electromagnetically induced transparency. We show that it is possible to construct an optical potential with PT symmetry… read more here.
