WHAT IS A PHOTON? Spontaneous emission
... accommodated in the usual quantum mechanical models based on particle mechanics. Instead, one must use a new class of models that go under the heading of quantum field theory. The reasons for this necessity are relatively simple if one focuses on spontaneous emission in atoms. This is where an atom ...

Chapter 1 Introduction: Why are quantum many
... The exponential growth of Hilbert space mentioned above appears prohibitive, but let us first stand back from the quantum problem for a moment. In classical mechanics there are enormous amounts of variables to keep track of once a system has macroscopic numbers of particles — Avogadro’s number is ve ...
