Representation zeta functions of compact p-adic analytic groups and arithmetic groups [PDF]

open access: yes, 2013
We introduce new methods from p-adic integration into the study of representation zeta functions associated to compact p-adic analytic groups and arithmetic groups.

Lattice simulations of the QCD chiral transition at real $\mu_B$

open access: yesSciPost Physics Proceedings, 2022
Most lattice studies of hot and dense QCD matter rely on extrapolation from zero or imaginary chemical potentials. The ill-posedness of numerical analytic continuation puts severe limitations on the reliability of such methods.

The QCD phase diagram from analytic continuation

open access: yesPhysics Letters B, 2015
We present the crossover line between the quark gluon plasma and the hadron gas phases for small real chemical potentials. First we determine the effect of imaginary values of the chemical potential on the transition temperature using lattice QCD ...

A GPU code for analytic continuation through a sampling method

open access: yesSoftwareX, 2016
We here present a code for performing analytic continuation of fermionic Green’s functions and self-energies as well as bosonic susceptibilities on a graphics processing unit (GPU). The code is based on the sampling method introduced by Mishchenko et al.

Quasi-analyticity and analytic continuation—a general principle [PDF]

open access: yesTransactions of the American Mathematical Society, 1944
1. All the results of this paper are based on a general principle (Theorem I) of an asymptotic character. We show that this theorem leads to results in branches of the theory of functions generally regarded as quite distinct from each other. All the results on Watson's problem, on the theory of quasianalyticity, on one hand, and many known results on ...

Average spectrum method for analytic continuation: Efficient blocked-mode sampling and dependence on the discretization grid [PDF]

open access: yesPhysical review B, 2019
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 noisy data from a functional average over all admissible spectral functions,

An analytic continuation of random analytic functions (in Ukrainian) [PDF]

open access: yesМатематичні Студії, 2011
Let $(eta_n(omega))$ be a sequence of independent randomvariables such that $eta_n(omega)$ takes the values $-1$ and$1$ with the probabilities $p_n$ and $1-p_n$, respectively. Put$q_n=min{p_n,1-p_n}$.

Curvature of the pseudocritical line in QCD: Taylor expansion matches analytic continuation [PDF]

open access: yesPhysical Review D, 2018
We determine the curvature of the pseudo-critical line of $N_f = 2 + 1$ QCD with physical quark masses via Taylor expansion in the quark chemical potentials. We adopt a discretization based on stout improved staggered fermions and the tree level Symanzik

Numerical analytic continuation of Euclidean data [PDF]

open access: yesComputer Physics Communications, 2018
In this work we present a direct comparison of three different numerical analytic continuation methods: the Maximum Entropy Method, the Backus–Gilbert method and the Schlessinger point or Resonances Via Pade method.
