概要
- 論文の詳細を見る
The spin depolarization of a particle in quantum states is considered using a modelof two sites, having different transverse magnetic fields, and between which the particle can tunnel. The ensemble average is performed with randccm distributions of themagnetic fields. A Gaussian decay law is obtained with the expc>nent reduced by a fac-tor 2, for all times when the system is prepared in suitable eigenstates and for longtimes with arbitrary preparation. The apparent contradiction to van Vleck's theoremis resolved.
