Conservation of Angular Momentum in a Flux Qubit
E. M. Chudnovsky, D. A. Garanin, M. F. O'Keeffe
Oscillations of superconducting current between clockwise and counterclockwise directions in a flux qubit do not conserve the angular momentum of the qubit. To compensate for this…

Quantum Tunneling of the Magnetic Moment in a Free Particle
M. F. O'Keeffe, E. M. Chudnovsky, D. A. Garanin
We study tunneling of the magnetic moment in a particle that has full rotational freedom. Exact energy levels are obtained and the ground-state magnetic moment is computed for a sy…
