Abstract
By means of the real-time temperature Green function method, the authors extend the one-pion exchange potential (OPEP) with pseudovector coupling and pseudoscalar coupling to finite density and finite temperature. After summing all the bubble diagrams of the exchange of the pion, they find that the density effects on the effective mass of pion and OPEP are considerable at low temperature. The density effects and the temperature effects of the OPEP are compared.Keywords
