Generalized squeezing operators, bipartite Wigner functions and entanglement via Wehrl's entropy functionals
Marcelo A. Marchiolli, Diogenes Galetti
We introduce a new class of unitary transformations based on the su(1,1) Lie algebra that generalizes, for certain particular representations of its generators, well-known squeezin…

Quantum spin tunneling of magnetization in small ferromagnetic particles
D. Galetti, B. M. Pimentel, C. L. Lima +1
A new quantum approach is presented that can account for the description of small ferromagnetic particles magnetization tunneling. An estimate of the saturation value of an externa…

Spin tunneling in magnetic molecules: Quantitative estimates for Fe8 clusters
D. Galetti, E. C. Silva
Spin tunneling in the particular case of the magnetic molecular cluster octanuclear iron(III), Fe8, is treated by an effective Hamiltonian that allows for an angle-based descriptio…
