Ghost-wave momentum bandgaps in anisotropic Floquet lattices
Junhua Dong, Huan He, Huanan Li
Momentum bandgaps, characterized by complex frequencies and non-resonant amplification effects, provide a powerful route for wave manipulation beyond conventional band theory. Here…

Longitudinal optical phonons in photonic time crystals containing a stationary charge
Sihao Zhang, Junhua Dong, Huanan Li +2
Lorentzian-type media support optical phonons that oscillate with longitudinal polarization parallel to the wave direction, at a wave vector-independent frequency at which the perm…

Non-uniform wave momentum bandgap in biaxial anisotropic photonic time crystals
Junhua Dong, Sihao Zhang, Huan He +2
Photonic time crystals (PTCs) host momentum bandgaps enabling intriguing non-resonant light amplification in propagating waves, but opening substantial bandgaps demands refractive…
