The study of light beams propagating in the nonlinear, dispersive, birefringent and nonlocal
medium of nematic liquid crystals has attracted widespread interest in the last twenty years …

We show that three-dimensional (3D) Dirac semimetals (DSMs) can achieve highly efficient
terahertz high-order harmonic generation (HHG) up to the 31st harmonic with input …

We provide experimental evidence that stable vortex-solitons in nematic liquid crystals,
termed vortex nematicons, can be generated in planar cells without any external biases …

We study the propagation dynamics of bright optical vortex solitons in nematic liquid crystals
with a nonlocal reorientational nonlinear response. We investigate the role of optical …

We investigate the optical propagation of reorientational solitary waves in nonuniformly
oriented planar samples of thermotropic liquid crystals in the nematic phase. A …

We analyze the dynamics of vortex solitons and the formation of soliton clusters with
controllable attributes in a nonlinear metamaterial waveguide. We consider the nonlinear …

We investigate two-dimensional modulation instability (MI) and higher-order soliton clusters
in nematic liquid crystals with competing re-orientational and thermal nonlocal …

Soliton attract a great deal of attention across various disciplines, from optics to fluid
mechanics, cosmology, as well as particle and condensed matter physics, due to their …

We investigate scalar and vector multi-hump spatial solitons resulting from competing Kerr-
like nonlinear responses excited in a nonlocal medium by either one or two (mutually …
