Probability distributions of squared free massless scalar field in four-dimensional Minkowski vacuum
摘要
Abstract
The moments for smeared squared free massless field φ2 in four-dimensional Minkowski vacuum were calculated and the probability distributions was found to be an approximate Γ distribution,thus the moment method was confirmed with a different type of sampling function.For this quadratic quantum field,it is more likely to find a negative value with a probability of 93 ％ in individual measurements.The bound from quantum energy inequalities was also found in this special case.关键词
