Optical lattice standing wave
WebWe describe a method to generate a synthetic gauge potential for ultracold atoms held in an optical lattice. Our approach uses a time-periodic driving potential based on quickly alternating two Hamiltonians to engineer the appropriate Aharonov-Bohm phases, and permits the simulation of a uniform tunable magnetic field. We explicitly demonstrate that … WebAn optical lattice is a periodic optical structure created by standing wave laser beams that give rise to the optical potential felt by the atoms in which cooled atoms are trapped (see …

WebJul 5, 2013 · The basic principle of optical lattices relies on the optical dipole force: when neutral atoms are subjected to an ac electric field, this field dynamically induces a polarization into the atom. The induced dipole moment, in turn, interacts with the electric field and a force is exerted onto the atom. WebFeb 21, 2024 · With the aid of spatial atomic density and standing wave modulation, both the optical PT symmetry and PT antisymmetry are achieved in one-dimensional and two-dimensional optical lattices, where the PT antisymmetry with the gain is presented.
WebPlasmonics is a revolutionary concept in nanophotonics that combines the properties of both photonics and electronics by confining light energy to a nanometer-scale oscillating field of free electrons, known as a surface plasmon. Generation, processing, routing, and amplification of optical signals at the nanoscale hold promise for optical …
