Approximating the mode of the non-central chi-squared distribution
Victor Ananyev, Alexander Lincoln Read
In this paper we consider the probability density function (PDF) of the non-central distribution with arbitrary number of degrees of freedom and non-centrality. For this func…

Light-by-light scattering sum rule for radiative transitions of bottomonia
Victor Ananyev, Igor Danilkin, Marc Vanderhaeghen
We generalize a forward light-by-light scattering sum rule to the case of heavy quarkonium radiative transitions. We apply such sum rule to the bottomonium states, and use availabl…

On the density of states of graphene in the nearest-neighbor approximation
V. O. Ananyev, M. I. Ovchynnikov
We propose an alternative analytical expression for the density of states of a clean graphene in the nearest-neighbor approximation. In contrast to the previously known expression,…
