Suppression of tunneling by interference in half-integer-spin particles.
Within a wide class of ferromagnetic and antiferromagnetic systems, quantum tunneling of magnetization direction is spin-parity dependent: it vanishes for magnetic particles with half-integer spin, but is allowed for integer spin. A coherent-state path integral calculation shows that this topological effect results from interference between tunneling paths.
متن کاملQuantum Tunneling in Half-Integer Spin Systems
Motivated by the experimental observations of resonant tunnelings in the systems with half-integer spin, such as V15 and Mn4, we study the mechanism of adiabatic change of the magnetization in systems with the time-reversal symmetry. Within the time-reversal symmetric models, effects of several types of perturbations are investigated. Although tunneling between the ground states is suppressed i...

15 صفحه اولRelativistic Coulomb problem for particles with arbitrary half - integer spin
Using relativistic tensor-bispinorial equations proposed in hep-th/0412213 we solve the Kepler problem for a charged particle with arbitrary half-integer spin interacting with the Coulomb potential. 1 Introduction Exactly solvable problems in quantum mechanics are quite important and illustrative but rather rare (see, e.g., [2]). They can be described fully and in a straightforward way free of ...
