Optical forces can be used to manipulate biological and colloidal material in a non-contact
manner. This forms the foundation of a wealth of exciting science, particularly in the fields of …

We demonstrate, theoretically and experimentally, nonbroadening optical beams
propagating along any arbitrarily chosen convex trajectory in space. We present a general …

We study atoms trapped with a harmonic confinement in an optical lattice characterized by a
flat band and Dirac cones. We show that such an optical lattice can be constructed which …

The existence of the edge states at the interface between two media with different
topological properties is protected by symmetry, which makes such states robust against …

The difference between boson and fermion dynamics in quasi-one-dimensional lattices is
studied by calculating the persistent current in small quantum rings and by exact simulations …

We introduce a novel class of planar, quasi-homogeneous Schell-model source for
producing far fields with optical lattice average intensity patterns and derive the …

In this paper we consider a generalization of standard nondiffracting parabolic beams. The
proposed generalized beams have two orders: a continuous parameter a, as in standard …

Recently, VV Kotlyar et al.[Opt. Lett. 39, 2395 (2014)] have theoretically proposed a novel
kind of three-parameter diffraction-free beam with a crescent profile, namely, the asymmetric …

We propose a simple method for the generation of multi-contour plane curves based on
vortex beam illumination of an optical element calculated using the Whittaker integral and …

We introduce an exactly integrable nonlinear model describing the dynamics of spinor
solitons in space-dependent matrix gauge potentials of rather general types. The model is …
