基于算子乘积展开的量子不等式
Quantum Inequalities from Operator Product Expansions
摘要:
量子不等式是具有正的经典对应物的量子可观测量的局部平均值的下限,例如能量密度或威克平方。我们建立这样的不等式一般(可能相互作用)量子场论闵可夫斯基空间,使用非微扰技术。我们的主要工具是严格版的算子乘积展开。
英文摘要:
Quantum inequalities are lower bounds for local averages of quantum observables that have positive classical counterparts, such as the energy density or the Wick square. We establish such inequalities in general (possibly interacting) quantum field theories on Minkowski space, using nonperturbative techniques. Our main tool is a rigorous version of the operator product expansion.
