Volume : II, Issue : XI, December - 2012 SUPERCONDUCTIVITY FROM WEAK TO STRONG COUPLING IN THE ATTRACTIVE HUBBARD MODEL: AN OVERVIEW ARUN KR. SINGH DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : In this review paper we will complement the analysis of the phase diagram to
finite temperature. But, still using exact diagonalization (ED) to solve the impurity
model associated with the DMFT of the Hubbard model. We also compare the normalstate
solutions with the superconducting solutions which are stable at low temperatures.
The use of ED allows us to reach arbitrarily small temperatures, which are hardly
accessible by means of QMC. Quite naturally, the extension of ED to finite temperature
requires a more severe truncation of the Hilbert space. Keywords : Article : Cite This Article : ARUN KR. SINGH, (2012).
