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…
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…
