Question
Since most potentials are well-approximated by a quadratic near equilibrium, these things can model basically every system in quantum and statistical mechanics. For 10 points each:
[10e] Name this simple model system, an example of whose use is Einstein’s model of a solid as a collection of identical examples of these systems. These systems have energy levels evenly spaced by a factor of h-bar omega.
ANSWER: quantum harmonic oscillators [or QHOs]
[10h] Inverting the Einstein model, this model of quantum dissipation assumes that the environment consists of an infinite number of coupled harmonic oscillators.
ANSWER: Caldeira–Leggett model [or harmonic bath model]
[10m] This process for constructing a quantum field theory from a classical one uses the creation and annihilation operators of the QHO as the field operators. States resulting from this process are elements of a Fock space.
ANSWER: second quantization [or canonical quantization; prompt on quantization; reject “first quantization”]
