TL;DR: This research offers significant and timely insight to AI technology and its impact on the future of industry and society in general, whilst recognising the societal and industrial influence on pace and direction of AI development.
Journal ArticleDOI
Complex Langevin method: When can it be trusted?
TL;DR: In this article, the authors analyze to what extent the complex Langevin method can be considered as reliable for solving the sign problems and give a formal derivation of the correctness and then point out various mathematical loopholes.
Journal ArticleDOI
Spectral functions at small energies and the electrical conductivity in hot quenched lattice QCD.
TL;DR: It is shown that at finite temperature the most commonly used algorithm, employing Bryan's method, is inherently unstable at small energies and a modification is given that avoids this.
Journal ArticleDOI
Complex Langevin: etiology and diagnostics of its main problem
TL;DR: In this article, the Langevin method is revisited and a necessary and sufficient criterion for correctness is derived, which is not practical in practice since checking an infinite tower of identities is computationally expensive.
Journal ArticleDOI
Electrical conductivity of the quark-gluon plasma across the deconfinement transition.
Anthony A. Amato,Anthony A. Amato,Gert Aarts,Chris Allton,Pietro Giudice,Pietro Giudice,Simon Hands,Jon-Ivar Skullerud +7 more
TL;DR: A lattice calculation is presented for the electrical conductivity σ of the QCD plasma with 2+1 dynamical flavors at nonzero temperature and an increase of σ/T across the transition is found.
