Type-II Dirac photonic lattices
Kaichao Jin, Hua Zhong, Yongdong Li +5
Different from the Fermi surface of the type-I Dirac semimetal being a point, that of the type-II Dirac semimetal is a pair of crossing lines because the Dirac cone is tilted with…
Parity-time-symmetric optical lattice with alternating gain and loss atomic configurations
Zhaoyang Zhang, Liu Yang, Jingliang Feng +4
Since the spatially extended periodic parity-time (PT) symmetric potential can possess certain unique properties compared to a single PT cell (with only a pair of coupled gain-loss…
Unveiling the link between fractional Schrödinger equation and light propagation in honeycomb lattice
Da Zhang, Yiqi Zhang, Zhaoyang Zhang +5
We establish a link between the fractional Schrödinger equation (FSE) and light propagation in the honeycomb lattice (HCL) - the Dirac-Weyl equation (DWE). The fractional Laplacian…
Transport properties in the photonic super-honeycomb lattice - a hybrid fermionic and bosonic system
Hua Zhong, Yiqi Zhang, Yi Zhu +6
We report on transport properties of the super-honeycomb lattice, the band structure of which possesses a flat band and Dirac cones, according to the tight-binding approximation. T…
Diffraction-free beams in fractional Schrödinger equation
Yiqi Zhang, Hua Zhong, Milivoj R. Belić +3
We investigate the propagation of one-dimensional and two-dimensional (1D, 2D) Gaussian beams in the fractional Schrödinger equation (FSE) without a potential, analytically and num…
Two-dimensional linear and nonlinear Talbot effect from rogue waves
Yiqi Zhang, Milivoj R. Belić, Milan S. Petrović +5
We introduce two-dimensional (2D) linear and nonlinear Talbot effects. They are produced by propagating periodic 2D diffraction patterns and can be visualized as 3D stacks of Talbo…
Three-dimensional nonparaxial accelerating beams from the transverse Whittaker integral
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We investigate three-dimensional nonparaxial linear accelerating beams arising from the transverse Whittaker integral. They include different Mathieu, Weber, and Fresnel beams, amo…
