Quantum Mechanical Operators - A Question Or Two

  1. Apr 25, 2013 #1
    A couple questions: is mass quantized? Energy is quantized, and momentum has eigenvalues for its operator so I took that to mean that momentum is also quantized.

    If those two are true (might not be! I'm new to this :tongue:), following

    E^2 = (pc)^2 + (mc^2)^2

    Would that not mean that mass is also quantized?

    And the actual question I wanted to ask:

    Is there an operator associated with mass?

    Energy is not necessarily quantised eg a free particle does not have energy quantised. Mass is gained by interaction with the Higgs field, but I am not expert enough in the theory to know if it implies mass is quantised - I don't think it does - but don't know the details well enough to be sure.

    And yes there is an operator associated with mass - its a scalar.

    Thanks
