Ground state mass in short lattices by controlling overconfidence and bias in Bayesian fits
Sourendu Gupta, Anirban Lahiri
We investigate the seemingly ill-defined problem of extracting a ground-state mass from a lattice simulation where the extent of the lattice is not long enough to project out the g…
Accelerating lattice QCD simulations with 2 flavours of staggered fermions on multiple GPUs using OpenACC - a first attempt
Sourendu Gupta, Pushan Majumdar
We present the results of an effort to accelerate a Rational Hybrid Monte Carlo (RHMC) program for lattice quantum chromodynamics (QCD) simulation for 2 flavours of staggered fermi…
Looking at the deconfinement transition using Wilson flow
Saumen Datta, Sourendu Gupta, Andrew Lytle
Wilson flow is an effective tool for constructing renormalized composite operators. We explore use of the Wilson flow to construct renormalized order parameters for the deconfineme…
Quark number susceptibilities and equation of state at finite chemical potential in staggered QCD with Nt=8
Saumen Datta, Rajiv V. Gavai, Sourendu Gupta
We report the measurement of quark number susceptibilities (QNS) and their temperature dependence from simulations of QCD with two flavours of light dynamical staggered quarks at f…
Bayesian priors and nuisance parameters
Sourendu Gupta, Anirban Lahiri
Bayesian techniques are widely used to obtain spectral functions from correlators. We suggest a technique to rid the results of nuisance parameters, ie, parameters which are needed…
Statistical tweaks and flow scale from masses
Saumen Datta, Sourendu Gupta, Anirban Lahiri +1
We compare lattice scales determined from the vector meson mass and the Wilson flow scale w_0 in QCD with two-flavours of rooted naive staggered fermions over a wide range of latti…
