The allowed energies are all positive and they go up to infinity.
So it's very counterintuitive.
And basically he does it by deforming contours in the complex plane.
It's a very elegant method, but there's a slight difference between what we're doing.
So you can say it is following.
Bender's method and Bender and Mannheim were interested in vial-squared gravity.
Actually, there are these two terms in quadratic gravity.
Most people are focused on the vial-squared gravity.
Because it has more symmetry, there's no length scale.
It is invariant under locally rescaling.
It has no scalar in the language.
The Ricci squared term has a scalar.
So we discovered...
that there's a limit where you can just ignore the vial squared and everything is in the scalar.
That's what we've been studying.
Ben Mannheim's focus was precisely on this vial squared gravity because he thinks maybe that's the kind of fundamental theory.
It has more symmetry.
But they still had to get rid of the negative norm states.
They did it in a way which essentially does the following.
I've got some states which have negative norm.
