    Dual topological states in the layered titanium-based oxypnictide superconductor BaTi2Sb2O

    Topological superconductors have long been predicted to host Majorana zero modes which obey non-Abelian statistics and have potential for realizing non-decoherence topological quantum computation. However, mat...

    Plain s-wave superconductivity in single-layer FeSe on SrTiO3 probed by scanning tunnelling microscopy

    Single-layer FeSe film on SrTiO3(001) has recently come to the fore as an interfacial superconducting system, with a transition temperature that is significantly enhanced with respect to bulk FeSe. The mechanism ...

    Laser-induced spectral broadening and hole-burning in rare earth doped crystals and coherent optical spectroscopy for frequency upconversion

    The excitation spectra for linear fluorescence and for frequency upconversion are recorded in Er3+ doped crystal Er:YAG. An excitation induced spectral broadening and hole-burning are shown to appear at the reson...
