Statistics of Peaks in Chi-Squared Fields
Jolyon K. Bloomfield, Stephen H. P. Face, Alan H. Guth +2
Chi-squared random fields arise naturally from the study of fluctuations in field theories with SO(n) symmetry. The extrema of chi-squared fields are of particular physical interes…

Number Density of Peaks in a Chi-Squared Field
Jolyon K. Bloomfield, Stephen H. P. Face, Alan H. Guth +3
We investigate the statistics of stationary points in the sum of squares of Gaussian random fields, which we call a "chi-squared" field. The behavior of such a field at a point…
