Abstract:

I will start with a quick review of the simple equation derived in 1963 to calculate the ground state energy E of a dilute  Bose gas with 2-body repulsive interactions. It yielded the famous LHY  second order term for E.  Beyond that it has been recently been shown  to agree remarkably well with Monte Carlo calculations in 3 dimensions  for ALL densities, revealing what might be  previously unsuspected  changes at intermediate density.
