Programmable branched flow of light
Shan-shan Chang, Daxing Xiong, Ze-huan Zheng +5
We demonstrate deterministic control of branched flow of light using anisotropic nematic liquid crystals. By sculpting the director field via photoalignment, we create spatially pr…
Thermal conductivity in one-dimensional nonlinear disordered lattices: Two kinds of scattering effects of hard-type and soft-type anharmonicities
Jianjin Wang, Chi Xiong, Daxing Xiong
The amorphous solids can be theoretically modeled by anharmonic disordered lattices. However, most of theoretical studies on thermal conductivity in anharmonic disordered lattices…
