Lattice -field correlators for heavy quarks
Luis Altenkort, David de la Cruz, Olaf Kaczmarek +2
We analyze the color-magnetic (or "") field two-point function that encodes the finite-mass correction to the heavy quark momentum diffusion coefficient. The simulations are don…
Quark Mass Dependence of Heavy Quark Diffusion Coefficient from Lattice QCD
Luis Altenkort, David de la Cruz, Olaf Kaczmarek +6
We present the first study of the quark mass dependence of the heavy quark momentum and spatial diffusion coefficients using lattice QCD with light dynamical quarks corresponding t…
Streamlined data analysis in Python
Luis Altenkort, David Anthony Clarke, Jishnu Goswami +1
Python is a particularly appealing language to carry out data analysis, owing in part to its user-friendly character as well as its access to well maintained and powerful libraries…
SIMULATeQCD: A simple multi-GPU lattice code for QCD calculations
Lukas Mazur, Dennis Bollweg, David A. Clarke +14
The rise of exascale supercomputers has fueled competition among GPU vendors, driving lattice QCD developers to write code that supports multiple APIs. Moreover, new developments i…
Heavy Quark Diffusion from 2+1 Flavor Lattice QCD with 320 MeV Pion Mass
Luis Altenkort, Olaf Kaczmarek, Rasmus Larsen +4
We present the first calculations of the heavy flavor diffusion coefficient using lattice QCD with light dynamical quarks. For temperatures ,…
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…
HotQCD on Multi-GPU Systems
Luis Altenkort, Dennis Bollweg, David Anthony Clarke +5
We present , HotQCD's software for performing lattice QCD calculations on GPUs. Started in late 2017 and intended as a full replacement of the previous single…
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…
