For example, it applies to plasma oscillations in a degenerate Fermi gas of
electrons in which all cells in velocity space are filled inside a sphere of radius
equal to the Fermi velocity VF. Then the average value of the square of a
component of velocity is <u2> = |VF2 (10.84) Quantum effects appear explicitly in
the dispersion equation only in higher- order terms in the expansion in powers of
k2. The oscillations described above are longitudinal electrostatic oscillations in
which the ...
10.9 Short- Wavelength Limit for Plasma Oscillations and the Debye Screening
Distance In the discussion of plasma oscillations so far no mention has been
made of the range of wave numbers over which the description in terms of
collective oscillations applies. Certainly ni/3 is one upper bound on the wave-
number scale. A clue to a more relevant upper bound can be obtained by
examining the dispersion relation (10.83) for the longitudinal oscillations. For
long wavelengths the ...
The Landau formula (10.93) shows that for k«kD the longitudinal plasma
oscillations are virtually undamped. But the damping becomes important as soon
as k~kD (even for k = 0.5kD, Im <o — — 0.7cop). For wave numbers larger than
the Debye wave number the damping is so great that it is meaningless to speak
of organized oscillations. Another, rather different consideration leads to the
same limiting Debye wave number as the boundary of collective oscillatory
effects. We know ...

A soul crushing technical manual written by a sadist that has served as the right of passage for physics PhDs since the dawn of time. Every single one of my professors studied this book, and every ... Read full review
Text is quite readable and appropriate for a first-year graduate text in physics. A "bible" I return to again and again.
Thinking back, I recall struggling over some sections for which I was not adequately prepared, including time-dependent EM fields. That aside, this was the text for my most favorite class in grad school.
If you are a fan of transformational solutions to differential equations then this is the text for you. Here is where I really learned about Fourier and other special function transformations as well as solving diffeq problems in special coordinate systems. I did very well in quantum mechanics thanks to this text.
I fear that students today may not have the same preparation that was common 30 years ago. Back then, expectations were different. In particular, this text is hardly aware of computational problem solving. It is focused on analytics.
