The clathrate hydrate,ice-like crystalline compounds comprised of guest molecules trapped inside hydrogen-bonded water cages,can be formed spontaneously by cooling and/or compressing a mixture of gas
As alternatives to the mixed-anion Cu2ZnSn(S,Se)4 (CZTSSe) alloys,the mixed-cation Cu2Zn(Sn,Ge)Se4 (CZTGSe) and Cu2Zn(Sn,Si)Se4 (CZTSiSe) alloys can also span a band gap range that fits the requiremen
As a promising source of multiferroic materials,transition metal oxides with the perovskite structure have drawn considerable interest for their variable electronic structures,and their defects,surfac
The entanglement was brought into the physical world with extraordinary properties and applications,and it plays vital roles in quantum information theoretically and experimentally.
The spontaneous evolution and emission spectrum of a Λ-type atom in the cavity made of a negative permeability material slab(MNG)and a negative permittivity material slab(ENG)is invested.In certain fr
The squeezed state is one of the key concepts in quantum optics and has wide applications in high-precision measurements.Squeezing of an optical field is defined as a reduction of the quantum fluctuat
