Pressure-induced color change arising from transformation between intra- and inter-band transitions in LuH2±xNy
The pressure-induced color change in the nitrogen-doped lutetium hydride has triggered extensive discussions about the underlying physics and potential applications. Here, we study the optical response of LuH2±xN

Open AccessTunable optical topological transitions of plasmon polaritons in WTe2 van der Waals films
Naturally existing in-plane hyperbolic polaritons and the associated optical topological transitions, which avoid the nano-structuring to achieve hyperbolicity, can outperform their counterparts in artificial ...
