| Abstract: | The quark condensate in nuclear matter is studied. We relate it to the nuclear sigma commutator, and then treat it as sigma commutator for quasi- particles in a self-consistent way. We find that the deviation from the linear expression is large at high density. Received: 20 November 1997 / Revised version: 24 February 1998 / Published online: 16 September 1998 |
