On the exact relationship between the denoising function and the data distribution
Heikki Arponen, Matti Herranen, Harri Valpola
We prove an exact relationship between the optimal denoising function and the data distribution in the case of additive Gaussian noise, showing that denoising implicitly models the…
Quantum corrections to inflation: the importance of RG-running and choosing the optimal RG-scale
Matti Herranen, Andreas Hohenegger, Asgeir Osland +1
We demonstrate the importance of correctly implementing RG-running and choosing the RG-scale when calculating quantum corrections to inflaton dynamics. We show that such correction…
High-energy evolution to three loops
Simon Caron-Huot, Matti Herranen
The Balitsky-Kovchegov equation describes the high-energy growth of gauge theory scattering amplitudes as well as nonlinear saturation effects which stop it. We obtain the three-lo…
Spacetime curvature and Higgs stability after inflation
Matti Herranen, Tommi Markkanen, Sami Nurmi +1
We investigate the dynamics of the Higgs field at the end of inflation in the minimal scenario consisting of an inflaton field coupled to the Standard Model only through the non-mi…
Quantum corrections to inflaton dynamics, the semi-classical approach and the semi-classical limit
Matti Herranen, Asgeir Osland, Anders Tranberg
Computations of quantum corrections to the CMB spectrum and to scalar field dynamics during inflation very often take advantage of the "semi-classical" approach, where the metric f…
Spacetime curvature and the Higgs stability during inflation
Matti Herranen, Tommi Markkanen, Sami Nurmi +1
It has been claimed that the electroweak vacuum may be unstable during inflation due to large fluctuations of order in case of a high inflationary scale as suggested by BICEP2.…
