Dephasing of Atomic Tunneling by Nuclear Quadrupoles
arXiv:cond-mat/0207384 · doi:10.1103/PhysRevLett.89.237601
Abstract
Recent experiments revealed a most surprising magnetic-field dependence of coherent echoes in amorphous solids. We show that a novel dephasing mechanism involving nuclear quadrupole moments is the origin of the observed magnetic-field dependence.
