自旋对磁场中旋转介质束缚态解离的贡献

Spin contribution to the dissociation of bound states in rotating medium in magnetic field

Kirill Tuchin

摘要:

磁旋转解离是旋转束缚态在磁场中以隧穿方式衰变的过程。最近在准经典近似中使用虚时方法计算了相应的概率,并显示出随角速度增加而随磁场强度\cite{Tuchin:2021lxl}减小。这封信报告的量子修正的计算与自旋的隧道粒子的解离概率。自旋的准经典运动在旋转坐标系下由Bargmann-Michel-Telegdi方程描述。结果表明,自旋贡献显着增加了解离几率。在夸克-胶子等离子体中的应用也被提及。

英文摘要:

Magneto-rotational dissociation is the decay, by the way of tunneling, of a rotating bound state in the magnetic field. The corresponding probability was recently computed in the quasi-classical approximation using the Imaginary Time Method and was shown to increase with the angular velocity and decrease with the magnetic field strength \cite{Tuchin:2021lxl}. This letter reports the calculation of the quantum correction to the dissociation probability associated with the spin of the tunneling particle. The quasi-classical motion of spin is described by the Bargmann--Michel--Telegdi equation in the rotating frame. It is shown that the spin contribution significantly increases the dissociation probability. Applications to the Quark-Gluon Plasma are touched upon.
