Hysteresis in the complex nonlinear refractive index of a homogeneous and isotropic medium
Igor Kuzmenko, Y. B. Band, Yshai Avishai +1
We calculate the permittivity, , for a medium with a quadratic electro-optic effect, modeling it as a Duffing oscillator. The nonlinear refractive index and the…
Negative Refraction in isotropic achiral and chiral materials
Y. B. Band, Igor Kuzmenko, Marek Trippenbach
We show that negative refraction in materials can occur at frequencies where the real parts of the permittivity $\veps(ω)$ and the permeability have different sign, and…
Fermionic atoms in a spin-dependent optical lattice potential: topological insulators with broken time-reversal symmetry
Igor Kuzmenko, Mirosław Brewczyk, Grzegorz Łach +2
We propose a novel approach to study the topological properties of matter. In this approach, fermionic atoms are placed in an external magnetic field and in a two-dimensional spin-…
Self-trapping and switching of solitonic pulses in mismatched dual-core highly nonlinear fibers
N. V. Hung, L. X. T. Tai, M. Longobucco +7
We investigate experimentally and theoretically effects of the inter-core propagation mismatch on nonlinear switching in dual-core high-index-contrast soft-glass optical fibers. In…
Optical Thouless pumping transport and nonlinear switching in a topological low-dimensional discrete nematic liquid crystal array
Pawel S. Jung, Midya Parto, Georgios G. Pyrialakos +6
We theoretically investigate a Thouless pumping scheme in the 1D topological Su-Schrieffer-Heeger (SSH) model for single and multiple band-gaps systems when implemented in a discre…
Atoms in a spin dependent optical potential: ground state topology and magnetization
Piotr Szulim, Marek Trippenbach, Y. B. Band +2
We investigate a Bose-Einstein condensate of Rb atoms in a 2D spin-dependent optical lattice generated by intersecting laser beams with a superposition of polarizatio…
