Issue Date: | 2004 | Citation: | The European Physical Journal A - Hadrons and Nuclei. 20:3 (2004) 459-467 | Abstract: | We present some applications of the renormalized RPA in bosonic field theories. We first present some developments for the explicit calculation of the total energy in $\Phi^4$ theory and discuss its phase structure in 1 + 1 dimensions. We also demonstrate that the Goldstone theorem is satisfied in the O( N) model within the renormalized RPA. | URI: | https://hdl.handle.net/10316/7696 | DOI: | 10.1140/epja/i2003-10164-5 | Rights: | openAccess |
