自旋巨系统时间反演实验中量子力学适用性极限的证明

Demonstration of the quantum mechanics applicability limits in time reversion experiments in spin macrosystems

V. A. Skrebnev, R. N. Zaripov

摘要:

对描述孤立自旋系统平衡建立过程的力学方程的适用性进行了实验研究。在实验中使用了时间反转效应。结果表明,力学方程并不能描述自旋宏观系统向平衡态的转变。实验结果与基于非平衡态热力学方法并考虑系统中互相关快速衰减的理论相一致。

英文摘要:

An experimental study of the applicability of mechanics equations to describing the process of equilibrium establishing in an isolated spin system was performed. The time-reversion effects were used at the experiments. It was demonstrated, that the equations of mechanics do not describe the spin macrosystem transition to the equilibrium. The experimental results correspond to the theory which is based on the non-equilibrium thermodynamics methods and takes into account the quick decay of cross-correlations in the systems.
