The Ising Model with Hybrid Monte Carlo
Johann Ostmeyer, Evan Berkowitz, Thomas Luu +2
The Ising model is a simple statistical model for ferromagnetism. There are analytic solutions for low dimensions and very efficient Monte Carlo methods, such as cluster algorithms…
Tetraquark interpolating fields in a lattice QCD investigation of the meson
Constantia Alexandrou, Joshua Berlin, Jacob Finkenrath +2
We investigate the meson using lattice QCD and considering correlation functions of several two-quark and four-q…
Nucleon strange electromagnetic form factors
C. Alexandrou, S. Bacchio, M. Constantinou +4
The role of the strange quarks on the low-energy interactions of the proton can be probed through the strange electromagnetic form factors. Knowledge of these form factors provides…
Ring Polymer Molecular Dynamics and Active Learning of Moment Tensor Potential for Gas-Phase Barrierless Reactions: Application to S + H2
Ivan S. Novikov, Alexander V. Shapeev, Yury V. Suleimanov
Ring polymer molecular dynamics (RPMD) has proven to be an accurate approach for calculating thermal rate coefficients of various chemical reactions. For wider application of this…
Nucleon axial, tensor and scalar charges and -terms in lattice QCD
C. Alexandrou, S. Bacchio, M. Constantinou +4
We determine the nucleon axial, scalar and tensor charges within lattice Quantum Chromodynamics including all contributions from valence and sea quarks. We analyze three gauge ense…
Moments of nucleon generalized parton distributions from lattice QCD simulations at physical pion mass
C. Alexandrou, S. Bacchio, M. Constantinou +9
We present results for the moments of nucleon isovector vector and axial generalised parton distribution functions computed within lattice QCD. Three ensembles of maximally twisted…
