QCD field-strength correlators on a Polyakov loop with gradient flow at next-to-leading order
David de la Cruz, Alexander M. Eller, Guy D. Moore
Momentum exchange between a heavy quark and a hot quark-gluon medium can be characterized nonperturbatively in terms of field-strength field-strength (E-E and B-B) correlators alon…
Viscosity of pure-glue QCD from the lattice
Luis Altenkort, Alexander M. Eller, Anthony Francis +4
We calculate shear viscosity and bulk viscosity in SU(3) gauge theory on the lattice at . The viscosities are extracted via a Kubo formula from the reconstructed spectra…
Lattice QCD noise reduction for bosonic correlators through blocking
Luis Altenkort, Alexander M. Eller, O. Kaczmarek +3
We propose a method to substantially improve the signal-to-noise ratio of lattice correlation functions for bosonic operators or other operator combinations with disconnected contr…
Continuum extrapolation of the gradient-flowed color-magnetic correlator at
Luis Altenkort, Alexander M. Eller, Olaf Kaczmarek +3
In a recently published work we employ gradient flow on the lattice to extract the leading contribution of the heavy quark momentum diffusion coefficient in the heavy quark limit f…
Spectral reconstruction details of a gradient-flowed color-electric correlator
Luis Altenkort, Alexander M. Eller, Olaf Kaczmarek +3
In a recently published work we provide a proof-of-concept of a novel method to extract the heavy quark momentum diffusion coefficient from color-electric correlators on the lattic…
The sphaleron rate from Euclidean lattice correlators: an exploration
Luis Altenkort, Alexander M. Eller, Olaf Kaczmarek +3
We show how the sphaleron rate (the Minkowski rate for topological charge diffusion) can be determined by analytical continuation of the Euclidean topological-charge-density two-po…
Heavy quark momentum diffusion from the lattice using gradient flow
Luis Altenkort, Alexander M. Eller, Olaf Kaczmarek +3
We apply the gradient flow on a color-electric two-point function that encodes the heavy quark momentum diffusion coefficient. The simulations are done on fine isotropic lattices i…
Thermal Heavy Quark Self-Energy from Euclidean Correlators
Alexander M. Eller, Jacopo Ghiglieri, Guy D. Moore
Brambilla, Escobedo, Soto, and Vairo have derived an effective description of quarkonium with two parameters; a momentum diffusion term and a real self-energy term. We point out th…
Gradient-flowed thermal correlators: how much flow is too much?
Alexander M. Eller, Guy D. Moore
Gradient flow has been proposed in the lattice community as a tool to reduce the sensitivity of operator correlation functions to noisy UV fluctuations. We test perturbatively unde…
