TL;DR: This work demonstrates experimentally passive PT-symmetry breaking within the realm of optics, which leads to a loss induced optical transparency in specially designed pseudo-Hermitian guiding potentials.
Journal ArticleDOI
Observation of accelerating Airy beams.
TL;DR: In this paper, the first observation of Airy optical beams has been reported in both one-and two-dimensional configurations, and they exhibit unusual features such as the ability to remain diffraction-free over long distances while they tend to freely accelerate during propagation.
Journal ArticleDOI
Accelerating finite energy Airy beams
TL;DR: This work investigates the acceleration dynamics of quasi-diffraction-free Airy beams in both one- and two-dimensional configurations and shows that this class of finite energy waves can retain their intensity features over several diffraction lengths.
Journal ArticleDOI
Realizing the Harper Hamiltonian with Laser-Assisted Tunneling in Optical Lattices
TL;DR: The Harper Hamiltonian for neutral particles in optical lattices is implemented using laser-assisted tunneling and a potential energy gradient provided by gravity or magnetic field gradients to describe the motion of charged particles in strong magnetic fields.
Journal ArticleDOI
Self-healing properties of optical Airy beams
TL;DR: This work investigates both theoretically and experimentally the self-healing properties of accelerating Airy beams and shows that this class of waves tends to reform during propagation in spite of the severity of the imposed perturbations.
