Quantum Relaxation of Ensembles of Nanomagnets
N. V. Prokof'ev, P. C. E. Stamp
Recent theory and experiment in crystals of molecular magnets suggest that fundamental tests of the decoherence mechanisms of macroscopic quantum phenomena may be feasible in these…

Short Time Quantum AC response of a system of Nanomagnets
G. Rose, P. C. E. Stamp
We calculate the magnetisation relaxation in the short-time regime for an ensemble of nanomagnets in the presence of a low-frequency external AC biasing field, at temperatures lowe…
