Answer to: Prove that the expectation value of momentum is zero whenever the wave function is real. By signing up, you'll get thousands of...
The main objective of this paper is to analyze the vacuum expectation value (VEV) of the energy-momentum tensor (EMT) associated with a charged scalar quantum field in a high-dimensional cosmic string spacetime admitting the presence of a magnetic flux running along the string's core. In ...
Define Expectation value. Expectation value synonyms, Expectation value pronunciation, Expectation value translation, English dictionary definition of Expectation value. n. 1. A quantity expressing a typical or average value of a random variable. 2. The
Recently, I started with principles of Quantum Mechanics by R.Shankar, and I got stuck at a part in my calculation of the Expectation value of Position and Momentum operator in the case where the particle is in one of the states. Starting with the Momentum operator, the eigenstates are ...

particle in a 1-D box. The expected value of the particle's momentum is zero because it has equal probability of moving either to the left or to the right, however zero is not the most probable speed, as it will always have some momentum. Mathematically the expectation value ...

where the superscripts in brackets indicate the loop order, and we put the momentum in the self-energy at the tree-level Higgs mass in order to respect the order of perturbation theory. In other words, the tadpole contribution is suppressed by the mass-squared of the Higgs, although – sinc...
