Generalized Maximum Entropy Methods as Limits of the Average Spectrum Method
Khaldoon Ghanem, Erik Koch
We show that in the continuum limit, the average spectrum method (ASM) is equivalent to maximizing Rényi entropies of order , of which Shannon entropy is the special case .…

The Average Spectrum Method for Analytic Continuation: Efficient Blocked Modes Sampling and Dependence on Discretization Grid
Khaldoon Ghanem, Erik Koch
The average spectrum method is a promising approach for the analytic continuation of imaginary time or frequency data to the real axis. It determines the analytic continuation of n…
