Effects of non-Hermitian perturbations on Weyl Hamiltonians with arbitrary topological charges
Alexander Cerjan, Meng Xiao, Luqi Yuan +1
We provide a systematic study of non-Hermitian topologically charged systems. Starting from a Hermitian Hamiltonian supporting Weyl points with arbitrary topological charge, adding…
Complete photonic bandgaps in supercell photonic crystals
Alexander Cerjan, Shanhui Fan
We develop a class of supercell photonic crystals supporting complete photonic bandgaps based on breaking spatial symmetries of the underlying primitive photonic crystal. One membe…
Achieving arbitrary polarization control using complex birefringent meta-materials
Alexander Cerjan, Shanhui Fan
We demonstrate that the key to realizing arbitrary control over pairs of polarization states of light, i.e. transforming an arbitrarily polarized pair of input states to an arbitra…
Effects of non-uniform distributions of gain and loss in photonic crystals
Alexander Cerjan, Shanhui Fan
We present a theory of photonic crystals containing gain and loss in which the gain and loss are added to separate primitive cells of the underlying H…
Eigenvalue dynamics in the presence of non-uniform gain and loss
Alexander Cerjan, Shanhui Fan
Loss-induced transmission in waveguides, and reversed pump dependence in lasers, are two prominent examples of counter-intuitive effects in non-Hermitian systems with patterned gai…
