标题： Dimensional Reduction and Quantum-to-Classical Reduction at High Temperatures

摘要： 我们讨论在有限温度下量子场论中的维度约化与一种熟悉的量子力学现象之间的关系，即在高温下量子效应变得可以忽略。 从这一角度来看，比较了费米场和玻色场。 我们表明，费米子从维度约化理论中的解耦可以与费米场不存在经典统计的特性相关联。 显示英文摘要

摘要： We discuss the relation between dimensional reduction in quantum field theories at finite temperature and a familiar quantum mechanical phenomenon that quantum effects become negligible at high temperatures. Fermi and Bose fields are compared in this respect. We show that decoupling of fermions from the dimensionally reduced theory can be related to the non-existence of classical statistics for a Fermi field.
