Abstract

We agree that our simulations of the two-dimensional quantum XY model differ from those of De Raedt and Lagendijk and argure that our results—a finite specific-heat peak and a conclusively nonzero vortex density at zero temperature—are the correct ones, agreeing with other work on this model.
