Title: | Variational principles in quantum statistical mechanics | Authors: | Providência, João da Fiolhais, Carlos |
Keywords: | Mecânica quântica estatística | Issue Date: | 1987 | Publisher: | Institute of Physics | Citation: | PROVIDÊNCIA, João da ; FIOLHAIS, Carlos – Variational principles in quantum statistical mechanics. European Journal of Physics. Bristol : Institute of Physics. ISSN 0143-0807. Vol. 8 (1987), p. 12-17 | Serial title, monograph or event: | European Journal of Physics | Volume: | 8 | Place of publication or event: | Bristol | Abstract: | The principle of least information is used to derive the inequality between the arithmetic and the geometric mean. Some important variational results in quantum statistical mechanics (Peierls and Bogolyubov inequalities) are pedagogically reviewed. Emphasis is put on the distinction between mixed states describing metastable and stable equilibrium. | URI: | https://hdl.handle.net/10316/40853 | ISSN: | 0143-0807 | DOI: | 10.1088/0143-0807/8/1/004 | Rights: | openAccess |
