    • Most authors so far explore the effect of modifying short-distance physics on scalar fluctuations by examining quantum fluctuations of a massless scalar field. The equation of motion obtained is actually closer to that for tensor modes than for scalar modes.

    • and Class. Quantum Grav. 15, 1401 (1998), who derived similar expressions to ours for power spectra under a general vacuum. For the scalar mode, we focus here on the gauge invariant curvature fluctuation, which reduces to the inflaton fluctuation under the uniform curvature gauge adopted by the above reference.

    • Starobinsky [7] argued that applying the same argument today gives a much stronger constraint. See [13] however for exceptions.
