摘要: A discrete quantum phase space formalism is used to discuss some basic aspects of the spin tunnelling which occurs in Fe8 magnetic clusters by means Wigner functions as well Husimi distributions. Those were obtained for sharp angle states and symmetric combinations lowest energy doublet—the particular doublet—with application an external field. The time evolution those carried out numerically allows one extract valuable information about dynamics under consideration, particular, coherent oscillations associated with doublet.
