Is a step in the primordial spectral index favored by CMB data ?
Minu Joy, Arman Shafieloo, Varun Sahni +1
A sudden small change in the second derivative of the inflaton potential can result in a universal local feature in the spectrum of primordial perturbations generated during inflat…

New Universal Local Feature in the Inflationary Perturbation Spectrum
Minu Joy, Varun Sahni, Alexei A. Starobinsky
A model is developed in which the inflaton potential experiences a sudden small change in its second derivative (the effective mass of the inflaton). An exact treatment demonstrate…

Inflationary Hubble Parameter from the Gravitational Wave Spectrum in the General Slow-roll Approximation
Minu Joy
Improved general slow-roll formulae giving the primordial gravitational wave spectrum are derived in the present work. Also the first and second order general slow-roll inverse for…
