Particularly at T = 0 using a suitable chemical potential, the two-gap SC in MgB<jats:sub>2<\/jats:sub> has been well described by the Res-Hartree-Bogoliubov theory (Res-HBT). The Res-HB ground state generated with HB wavefunctions almost exhausts the ground-state correlation energy in all the correlation regimes. In this paper we make an attempt at a Res-MF theoretical description of thermal behavior of the two-gap SC. In an equal energy-gap case we find a new formula leading to a higher critical temperature T<jats:sub>c<\/jats:sub> than the T<jats:sub>c<\/jats:sub> of the usual HB formula. <\/jats:p>","DOI":"10.1142\/s0217979213500793","type":"journal-article","created":{"date-parts":[[2013,6,4]],"date-time":"2013-06-04T11:23:49Z","timestamp":1370345029000},"page":"1350079","source":"Crossref","is-referenced-by-count":1,"title":["AN ATTEMPT AT A RESONATING MEAN-FIELD THEORETICAL DESCRIPTION OF THERMAL BEHAVIOR OF TWO-GAP SUPERCONDUCTIVITY"],"prefix":"10.1142","volume":"27","author":[{"given":"SEIYA","family":"NISHIYAMA","sequence":"first","affiliation":[{"name":"Centro de F\u00edsica Computacional, Departamento de F\u00edsica, Universidade de Coimbra, P-3004-516 Coimbra, Portugal"}]},{"given":"JO\u00c3O","family":"DA PROVID\u00caNCIA","sequence":"additional","affiliation":[{"name":"Centro de F\u00edsica Computacional, Departamento de F\u00edsica, Universidade de Coimbra, P-3004-516 Coimbra, Portugal"}]},{"given":"CONSTAN\u00c7A","family":"PROVID\u00caNCIA","sequence":"additional","affiliation":[{"name":"Centro de F\u00edsica Computacional, Departamento de F\u00edsica, Universidade de Coimbra, P-3004-516 Coimbra, Portugal"}]},{"given":"HIROMASA","family":"OHNISHI","sequence":"additional","affiliation":[{"name":"Nanosystem Research Institute (NRI), National Institute of Advanced Science and Technology (AIST), 1-1-1, Umezono, Tsukuba, Ibaraki 305-8568, Japan"}]}],"member":"219","published-online":{"date-parts":[[2013,7,3]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1038\/35065039"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRev.108.1175"},{"key":"rf4","volume-title":"A New Method in the Theory of Superconductivity","author":"Bogoliubov N.
