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

A GPU code for analytic continuation through a sampling method
SoftwareX, 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.

Analytic continuation of dimensions in supersymmetric localization
Journal of High Energy Physics, 2018 We compute the perturbative partition functions for gauge theories with eight supersymmetries on spheres of dimension d ≤ 5, proving a conjecture by the second author. We apply similar methods to gauge theories with four supersymmetries on spheres with d

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

An analytic continuation of random analytic functions (in Ukrainian) [PDF]
Математичні 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$q_n=min{p_n,1-p_n}$.

Inclusive B decay calculations with analytic continuation
EPJ Web of Conferences, 2018 First-principle lattice calculation of inclusive B meson semileptonic decays is possible for a certain class of moments that is connected to the structure function at unphysical kinematics by analytic continuation.

On the Analytic Continuation of Lauricella–Saran Hypergeometric Function FK(a1,a2,b1,b2;a1,b2,c3;z)
Mathematics, 2023 The paper establishes an analytical extension of two ratios of Lauricella–Saran hypergeometric functions FK with some parameter values to the corresponding branched continued fractions in their domain of convergence.

Janus interface in two-dimensional supersymmetric gauge theories
Journal of High Energy Physics, 2019 We study the Janus interface, a domain wall characterized by spatially varying couplings, in two-dimensional N $$ \mathcal{N} $$ = (2, 2) supersymmetric gauge theories on the two-sphere.

Analytic Continuation of the Hurwitz Transform
MathematicsAn integral over the unit interval of the product of a given function and the Hurwitz zeta function is known as the Hurwitz transform of the function. We give sufficient conditions on the function for the Hurwitz transform to continue meromorphically to ...

Open strings on the Rindler horizon
Journal of High Energy Physics, 2019 It has been proposed that a certain ℤ N orbifold, analytically continued in N, can be used to describe the thermodynamics of Rindler space in string theory. In this paper, we attempt to implement this idea for the open-string sector. The most interesting
