The operators we introduce are called creation and annihilation operators, names that are taken from the quantum treatment of light (i.e. photons).

In this chapter we shall describe an operator formalism that has widespread applications in quantum mechanics, notably in dealing with harmonic oscillators.

Hence, the coherent states with |a| 1 play the role of the quasi-classical states, the annihilation operator behaving as classical complex canonical variable a ...

1.1 Creation and Annihilation Operators in Quan- tum Mechanics. We will begin with a quick review of creation and annihilation operators in the non ...

vibrational excitation. We call aˆ †, aˆ “ladder operators” or creation and annihilation operators (or step-up, step-down).

This document provides an introduction to the concept of second quantization and the creation/annihilation operator formalism for quantum field theory.
