Optically activated high Tc superconducting microbolometer

Applications using high-Tc superconducting terahertz emitters

Using recently-developed THz emitters constructed from single crystals of the high-Tc superconductor Bi2Sr2CaCu2O8+δ, we performed three prototype tests of the devices to demonstrate their unique characteristic properties for various practical applications. The first is a compact and simple transmission type of THz imaging system using a Stirling cryocooler. The second is a high-resolution Mich...

Modeling of superconducting stripe phases in high-Tc cuprates

Even before the experimental discovery of spinand charge-stripe order in La2−x−yNdySrxCuO4 and La2−xBaxCuO4 at x = 1/8, stripe formation was predicted from theoretical considerations. Nevertheless, a consistent description of the complex coexistence of stripe order with superconductivity has remained a challenge. Here we introduce a Hartree–Fock decoupling scheme that unifies previous approache...
