Dynamic Equivalence of a Two-Dimensional Quantum Electron Gas and a Classical Harmonic Oscillator Chain with an Impurity Mass

摘要

There is an exact equivalence in the time-dependent behavior of a zero-temperature two-dimensional interacting electron gas at long wavelengths and a classical harmonic oscillator chain with one impurity mass. The mass difference m - m sub0, where m sub 0 is the impurity mass, acts as the electron-electron interaction. Time evolution is asymmetric in m - m sub 0 about m - m sub 0. Reprints. (jhd)
