On the degrees of freedom of spatially covariant vector field theory
Shu-Yu Li, Xian Gao
We investigate a class of spatially covariant vector field theories on a flat background, where the Lagrangians are constructed as polynomials of first-order derivatives of the vec…

Single-photon scattering in giant-atom waveguide systems with chiral coupling
Shu-Yu Li, Ze-Quan Zhang, Lei Du +2
We study single-photon scattering spectra of a giant atom chirally coupled to a one-dimensional waveguide at multiple connection points, and examine chirality induced effects in th…
