The two articles which are now available are numbered 1111.6919 and 1111.6940: Calculating Non-adiabatic Pressure Perturbations during Multi-field Inflation Ian Huston, Adam J. Christopherson Abstract: [...]

The new results do not assume slow-roll in the calculation of the source term for the second order equations of motion and so allow a much greater [...]
