Abstract/OtherAbstract:
We report a high-pressure single crystal study of the topological superconductor Cu_{x}Bi_{2}Se_{3}. Resistivity measurements under pressure show superconductivity is depressed smoothly. At the same time the metallic behavior is gradually lost. The upper-critical field data B_{c2}(T) under pressure collapse onto a universal curve. The absence of Pauli limiting and the comparison of B_{c2}(T) to a polar-state function point to spin-triplet superconductivity, but an anisotropic spin-singlet state cannot be discarded completely.
