摘要：We present two improvements to our previous dynamical overlap HMC algorithm. We introduce
a new method of differentiating the eigenvectors of the Kernel operator, which removes an instability
in the fermionic force. Secondly, by simulating part of the fermion determinant exactly,
without pseudo-fermions, we are able to increase the rate of topological tunnelling by a factor of
more than ten, reducing the auto-correlation.
