Theory of scanning tunneling microscopy measurement of single spin decoherence in a superconductor.

Localized spin states in conventional superconductors at low temperatures are expected to have a long decoherence time due to the strong suppression of spin relaxation channels. We propose a scanning tunneling microscopy (STM) experiment allowing the direct measurement of the decoherence time of a single spin in a conventional superconductor. The… CONTINUE READING
