Topological phase transition based on the attractive Hubbard model
Fenghua Qi, Jun Cao, Jie Cao +2
We theoretically investigate the effect of an attractive on-site interaction on the two-band magnetic Dirac fermion model based on a square lattice system. When the attractive ferm…

High-efficiency waveguide couplers via impedance-tunable transformation optics
Jun Cao, Lifa Zhang, Weifeng Jiang +2
We design compact waveguide couplers via impedance-tunable transformation optics. By tuning impedance coefficients in the original space, two-dimensional metallic and dielectric wa…

Reflectionless design of optical elements using impedance-tunable coordinate transformation
Jun Cao, Lifa Zhang, Senlin Yan +1
We report a new strategy to remove the reflections resulted from the finite embedded transformation-optical design by proposing an impedance-tunable coordinate transformation, on w…
