Hello condensed matter gurus out there,
I'm a new graduate student who's been trying to understand some sentences in a review article that reads:
-----
... One of Feynman's early successes with path integrals is often neglected, his mapping with path integrals of a quantum system onto a classical model of interacting "polymers." The polymers are ring exchanges of bosons in imaginary time. ...
-----
Now I have no clue what "ring exchanges" are... can anyone briefly explain it to me or point me to a reference? Google wasn't too helpful when I fed it ring, exchange, interaction, etc.
Thanks in advance.
PS. by the way, this article is Rev.Mod.Phys., v67 p279 by D.M. Ceperley
