The proximity effect from the superconductor modifies the conductance of the remote current depending remarkably on the pairing symmetry: spin singlet or spin triplet. The clear-cut difference in the conductance is explained by symmetry of Cooper pairs in a normal metal with respect to frequency. In the spin-triplet case, the anomalous transport is realized due to an odd-frequency symmetry of Cooper pairs.American Physical SocietyJournal Articleapplication/pdfhttp://hdl.handle.net/2115/29633https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/29633/1/PRL99-6.pdf0031-90071079-7114Physical Review Letters9960670052007-08-10enginfo:pmid/17930859info:doi/10.1103/PhysRevLett.99.067005Copyright © 2007 American Physical Societypublisher
