GROUND STATE ENERGY OF THE TWO-COMPONENT CHARGED BOSE GAS

ABSTRACT.  We continue the study of the two-component charged Bose gas 
initiated by Dyson in 1967. He showed that the ground state energy 
for $N$ particles is at least as negative as $-CN^{7/5}$ for large 
$N$ and this power law was verified by a lower bound found by Conlon, Lieb and Yau in 1988. Dyson conjectured that the exact constant $C$ was given by a mean-field minimization problem that used, as input, Foldy's 
calculation (using Bogolubov's 1947 formalism) for the one-component 
gas. Earlier we showed that Foldy's calculation is exact insofar as 
a lower bound of his form was obtained. In this paper we do the same 
thing for Dyson's conjecture. The two-component case is considerably 
more difficult because the gas is very non-homogeneous in its ground 
state.
