In quantum field theory a product of quantum fields, or equivalently their creation and annihilation operators, is usually said to be normal ordered (also called Wick order) when all creation operators are to the left of all annihilation operators in the product. The process of putting a product into … Ver mais If $${\displaystyle {\hat {O}}}$$ denotes an arbitrary product of creation and/or annihilation operators (or equivalently, quantum fields), then the normal ordered form of $${\displaystyle {\hat {O}}}$$ is denoted by Ver mais Fermions are particles which satisfy Fermi–Dirac statistics. We will now examine the normal ordering of fermionic creation and annihilation operator products. Ver mais The most general definition of normal ordering involves splitting all quantum fields into two parts (for example see Evans and Steer 1996) Ver mais Bosons are particles which satisfy Bose–Einstein statistics. We will now examine the normal ordering of bosonic creation and annihilation operator products. Single bosons If we start with only … Ver mais The vacuum expectation value of a normal ordered product of creation and annihilation operators is zero. This is because, denoting the vacuum state by Ver mais Webfor the general n-mode cases, we can derive the normally ordered form of n-mode U by applying IWOP to (2.9) as in the one-mode and two-mode cases. Then combined with (3.5), we will get the normally ordered form of U which is the same as those derived by other approaches [3,4]. siga and family services lake worth fl
