Instability in the Hartmann--Hahn double resonance
arXiv:2005.09298 · doi:10.1103/PhysRevA.102.053516
Abstract
The Hartmann-Hahn technique allows sensitivity enhancement of magnetic resonance imaging and spectroscopy by coupling the spins under study to another spin species that is externally driven. Here we theoretically study the coupled spins' dynamics, and find that for a certain region of driving parameters the system becomes unstable. The required conditions for making this region of instability becoming experimentally accessible are discussed.
