We demonstrate that the canonical change of variables that yields the MHV lagrangian, also provides contributions to scattering amplitudes that evade the equivalence theorem. This `ET evasion' in particular provides the tree-level (−++) amplitude, wh... Read More about S-matrix equivalence theorem evasion and dimensional regularisation with the canonical MHV lagrangian.

Leonard, D., & Mansfield, P. (2007). Solving the anharmonic oscillator: Tuning the boundary condition. Journal of Physics A: Mathematical and Theoretical, 40(33),

We outline a remarkably efficient method for generating solutions to quantum anharmonic oscillators with an x2M potential. We solve the Schroedinger equation in terms of a free parameter which is then tuned to give the correct boundary condition by g...
