On loss of quantum coherence in an interacting Fermi gas
We clarify the path integral calculation, recently suggested by Golubev and Zaikin, and show, contrary to their claim, that quasiparticles become fully coherent quantum particles in the $T \to 0$ limit. The important physical point is the inclusion of the recoil of the quasiparticle when interacting...

Summary: | We clarify the path integral calculation, recently suggested by Golubev and
Zaikin, and show, contrary to their claim, that quasiparticles become fully
coherent quantum particles in the $T \to 0$ limit. The important physical point
is the inclusion of the recoil of the quasiparticle when interacting with
fluctuations in the rest of the Fermi gas. |
