It is the main purpose of this paper to calculate the energy splitting of ground state and excited states induced by thermally assisted quantum tunneling . first , a brief introduction is given for the theoretical and experimental studies on the magnetic macroscopic quantum effects . then , spin tunneling in a uniaxial ferromagnetic particle in transverse magnetic field is converted to a pseudoparticle moving in effective double - well potential with the help of the effective potential description of quantum spin systems developed by ulyanov and zaslavskii . finally using the periodic instanton method we evaluate the transition amplitude , energy shift and prefactor of wkb exponential and the energy splitting of ground state and the tunneling rate for excited states induced by thermally assisted quantum tunneling are obtained 文章首先對磁性宏觀量子效應的理論和實驗方面作了簡單介紹,然后借助于ulyanov和zaslavskii發展的一種等效勢描述方法,把外磁場沿難磁化軸方向時的自旋隧穿約化成在等效雙勢阱中運動的粒子,利用瞬子方法給出基態能級劈裂,最后利用周期瞬子方法分別計算了隧穿幅、能級移動以及wkb前因子,從而給出由于熱助量子隧穿引起的激發態的隧穿率。 |

For the transition induced by the asymmetric perturbations is double - direction , the particle number in the core state is always less half of the total particle number . so , from the point of view of average over time , it is a coexisting state of rotating and without rotating that is formed . this state which is in the josephson tunneling regime of the macroscopic quantum tunneling is a quantum self - trapping state 由于不對稱的微擾引起的躍遷是雙向的,使得核心態上的粒子數總是少于總粒子數的一半,因此從時間平均的角度看,形成的是旋轉的和不旋轉的態共存的狀態,而且處于宏觀量子隧穿的約瑟夫森隧穿區域中,是量子自束縛狀態。 |
