dc.descriptionWe present the results of quantum-mechanical calculations, using the singular gauge transformation of Franz and Tesanovic, of the rate of planar Cu spin-lattice relaxation due to electron spin-flip scattering in the mixed state of high-Tc cuprate superconductors. The results show a non-monotonic temperature and frequency dependence that differs markedly from semiclassical Doppler-shifted results and challenges the assertion that recent experimental observations of the rate of planar Cu and O spin-lattice relaxation in the mixed state of YBCO point to antiferromagnetic spin fluctuations as a better candidate for the elementary excitations of the superconducting state.
