Evidence for a new excitation at the interface between a high-Tc superconductor and a topological insulator
High-temperature superconductors exhibit a wide variety of novel excitations. If contacted with a topological insulator, the lifting of spin rotation

Origin of the insulating state in exfoliated high-Tc two-dimensional atomic crystals
We present the results of an optical spectroscopic study of two-dimensional atomic crystals of the high- temperature superconductor Bi2Sr2CaCu2O8+δ. Our

α−RuCl3: A spin-orbit assisted Mott insulator on a honeycomb lattice
We examine the role of spin-orbit coupling in the electronic structure of α−RuCl3, in which Ru ions in 4d5 configuration form

Cooper-pair-based photon entanglement without isolated emitters
We show that the recombination of Cooper pairs in semiconductors can be used as a natural source of polarization-entangled photons,
