1. In many cases, the particle number operator does not time-energy uncertainty principle in a vacuum.
2. This clearly satisfies the requirements of the above definition of a ladder operator : the incrementing or decrementing of the eigenvalue of another operator ( in this case the particle number operator ).
3. In formal terms, a particle is considered to be an eigenstate of the particle number operator a a, where a is the particle annihilation operator and a the particle creation operator ( sometimes collectively called ladder operators ).
4. The identification of a ^ \ dagger _ r ( \ mathbf { p } ) and as creation and annihilation operators comes from comparing conserved quantities for a state before and after one of these have acted upon it . a ^ \ dagger _ r ( \ mathbf { p } ) can for example be seen to add one particle, because it will add to the eigenvalue of the a-particle number operator, and the momentum of that particle ought to be since the eigenvalue of the vector-valued momentum operator increases by that much.
5. It's difficult to find particle number operator in a sentence. 用particle number operator造句挺難的
