Strong coupling constant from the 1-loop improved static energy

Viljami Leino, Alexei Bazavov, Nora Brambilla +8

The static energy is an excellent observable for extracting the strong coupling on the lattice. For short distances, the static energy can be calculated both on the lattice u…

Strong coupling in (2+1+1)-flavor QCD

Viljami Leino, Alexei Bazavov, Nora Brambilla +6

The strong coupling can be obtained from the static energy as shown in previous lattices studies. For short distances, the static energy can be calculated both on th…

Charm mass effects in the static energy computed in 2+1+1 flavor lattice QCD

Johannes Heinrich Weber, Nora Brambilla, Rafael L. Delgado +5

We report our analysis for the static energy in (2+1+1)-flavor QCD over a wide range of lattice spacings and several quark masses. We obtain results for the static energy out to di…

QuantumFDTD -- A computational framework for the relativistic Schrödinger equation

Rafael L. Delgado, Sebastian Steinbeißer, Michael Strickland +1

We extend the publicly available quantumfdtd code. It was originally intended for solving the time-independent three-dimensional Schrödinger equation via the finite-difference time…

Static Energy in ()-Flavor Lattice QCD: Scale Setting and Charm Effects

TUMQCD Collaboration, Nora Brambilla, Rafael L. Delgado +6

We present results for the static energy in ()-flavor QCD over a wide range of lattice spacings and several quark masses, including the physical quark mass, with ensembles o…

Chromo-electric screening length in 2+1 flavor QCD

Peter Petreczky, Sebastian Steinbeißer, Johannes Heinrich Weber

We study Polyakov loop as well as correlators of real and imaginary parts of the Polyakov loop in 2+1 flavor QCD at finite temperature. We use hypercubic (HYP) smearing to improve…

The static energy in 2+1+1-flavor QCD

Sebastian Steinbeißer, Nora Brambilla, Rafael L. Delgado +5

We report on the status of the analysis of the static energy in -flavor QCD. The static energy is obtained by measuring Wilson line correlators in Coulomb gauge using the HI…

The Relativistic Schrödinger Equation through FFTW3: An Extension of quantumfdtd

Rafael L. Delgado, Sebastian Steinbeißer, Michael Strickland +1

In order to solve the time-independent three-dimensional Schrödinger equation, one can transform the time-dependent Schrödinger equation to imaginary time and use a parallelized it…

Heavy quarkonium electric dipole transitions in non-relativistic quantum field theory

Sebastian Steinbeißer

In this work we use the low-energy EFT called potential non-relativistic QCD (pNRQCD) to calculate the partial decay width of different -states undergoing an electric dip…

Color screening in flavor QCD at large distances

Sebastian Steinbeißer, Johannes Heinrich Weber

We study correlation functions of spatially separated static quark-antiquark pairs in flavor QCD in order to investigate the nature of color screening at high temperatures. W…
