Viewing Message ``Legendre transformations of the generating functional of connected Green functions.'' by andrew on 2009-02-21 16:28:28 Hi, Please post a set of lecture notes and references about the Legendre transformations (LT) of the generating functional of connected Green functions. These are "effective potentials" corresponding to 1PI diagrams for the first LT, to 2PI diagrams for the second LT, etc. This would include definitions, properties and physical interpretation. Applications to spontaneous symmetry breaking in \phi^4, Bose-Einstein condensation and BCS would be greatly appreciated. Thank you, Andrew [ reply | up ] Re: Legendre transformations of the generating functional of connected Green functions. by bci1 on 2009-02-21 16:33:09 Re: Legendre transformations of the generating functional of connected Green functions. by bci1 on 2009-02-22 16:55:17 Re: Legendre transformations of the generating functional of connected Green functions. by bci1 on 2009-02-22 17:07:29 Interact reply
