... A vibration is a back and forth motion (p289). Now, moving any mass back and forth requires acceleration and a force to push or pull it. Energy is needed to get a vibration started—work has to be done on the mass. ...

... But it is entirely a matter of tast if you like to schlepp along the signs all the time, or if you like to fill 'em in at the end. Everything more detailed then this is no longer universal but specific for certain materials. The remaining task is to calculate n and μ for given materials (or groups o ...

Density of states

In solid-state and condensed matter physics, the density of states (DOS) of a system describes the number of states per interval of energy at each energy level that are available to be occupied. Unlike isolated systems, like atoms or molecules in gas phase, the density distributions are not discrete like a spectral density but continuous. A high DOS at a specific energy level means that there are many states available for occupation. A DOS of zero means that no states can be occupied at that energy level. In general a DOS is an average over the space and time domains occupied by the system. Localvariations, most often due to distortions of the original system, are often called local density of states (LDOS). If the DOS of an undisturbedsystem is zero, the LDOS can locally be non-zero due to the presence of a local potential.
