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…
Observation of electromagnetically induced Talbot effect in an atomic system
Zhaoyang Zhang, Xing Liu, Dan Zhang +4
We experimentally demonstrate the Talbot effect resulting from the repeated self-reconstruction of a spatially intensity-modulated probe field under the Fresnel near-field regime.…
New face-centered photonic square lattices with flat bands
Yiqi Zhang, Milivoj R. Belić, Changbiao Li +3
We report two new classes of face-centered photonic square lattices with flat bands which we call the Lieb-I and the Lieb-II lattices. There are 5 and 7 sites in the corresponding…
Observation of Parity-Time Symmetry in Optically Induced Atomic Lattices
Zhaoyang Zhang, Yiqi Zhang, Jiteng Sheng +6
We experimentally demonstrate PT-symmetric optical lattices with periodical gain and loss profiles in a coherently-prepared four-level N-type atomic system. By appropriately tuning…
symmetry in a fractional Schrödinger equation
Yiqi Zhang, Hua Zhong, Milivoj R. Belić +5
We investigate the fractional Schrödinger equation with a periodic -symmetric potential. In the inverse space, the problem transfers into a first-order nonlocal frequ…
