Variational theory of binary boson mixture atT=0K

Abstract
We present a general formalism for the ground state of binary boson mixtures where the Jastrow-type ground-state wave function is optimized by solving the Euler-Lagrange equations in the hypernetted-chain scheme. This method is expected to provide more accurate information for the binary boson systems compared to the methods currently available. For the isotopic T↑-H↑ mixture, complete phase separation in its ground state is observed.
