Abstract

A construction of the Wehrl entropy is proposed for an arbitrary locally compact abelian group \(G\). It is proved that the Wehrl entropy is not less than a certain nonnegative integer, which is an invariant of the group \(G\). The minimum of the Wehrl entropy is attained on coherent states.

论局部紧凑阿贝尔群的韦尔熵最小值

摘要针对任意局部紧密无性群 \(G\) 提出了韦尔熵的构造。证明了韦尔熵不小于某个非负整数，而这个非负整数是群\(G\) 的不变式。韦尔熵的最小值是在相干态上达到的。
