Abstract
The manner in which the interactions (‘coupling’) between excitations in solids (for example, phonons and electrons) vary with parameters such as temperature or magnetic field not only gives information on the density of states, but can also provide for novel measurements of specific heat of a single set of excitations. The particular example of a two-dimensional electron gas confined to a GaAs-AlGaAs single quantum well is discussed, along with preliminary measurements on the decoupling of electrons and phonons in magnetic field at low temperatures.
