Based on Fermats principle and the special relativity,the transmission of high-frequency electromagnetics is unified by variational formulation on the moving in
The Fibonacci piezoelectric superlattices (FPSs) with an exteal dc electric field is presented,in which the dc electric field can tune the bandwidth of polarito
We study the quasinormal modes (QNMs) of massless scalar perturbations to probe the van der Waals like SBH/LBH phase transition of anti-de Sitter black holes in
An intrinsic magnetic topological insulator (TI) is a stoichiometric magnetic compound possessing both inherent magnetic order and topological electronic states
