Testing a non-perturbative mechanism for elementary fermion mass generation: lattice setup [PDF]

, 2018
In this contribution we lay down a lattice setup that allows for the nonperturbative study of a field theoretical model where a SU(2) fermion doublet, subjected to non-Abelian gauge interactions, is also coupled to a complex scalar field doublet via a ...

Mean field approximation for effective theories of lattice QCD

, 2022
For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime.

Phase diagram and Chiral Magnetic Effect in Dirac Semimetals from Lattice Simulation

EPJ Web of Conferences, 2018
Dirac Semimetals Na3Bi and Cd3As2 are recently discovered materials, which low energy electronic spectrum is described by two flavours of massless 3+1D fermions.

RG-inspired machine learning for lattice field theory

EPJ Web of Conferences, 2018
Machine learning has been a fast growing field of research in several areas dealing with large datasets. We report recent attempts to use renormalization group (RG) ideas in the context of machine learning.

Thermal QCD in a non-uniform magnetic background

Journal of High Energy Physics, 2023
Off-central heavy-ion collisions are known to feature magnetic fields with magnitudes and characteristic gradients corresponding to the scale of the strong interactions.

Effective Field Theory for Lattice Nuclei

Physical Review Letters, 2015
We show how nuclear effective field theory (EFT) and ab initio nuclear-structure methods can turn input from lattice quantum chromodynamics (LQCD) into predictions for the properties of nuclei. We argue that pionless EFT is the appropriate theory to describe the light nuclei obtained in recent LQCD simulations carried out at pion masses much heavier ...

Soliton quantization in lattice field theories [PDF]

Communications in Mathematical Physics, 1987
Quantization of solitons in terms of Euclidean region functional integrals is developed, and Osterwalder-Schrader reconstruction is extended to theories with topological solitons. The quantization method is applied to several lattice field theories with solitons, and the particle structure in the soliton sectors of such theories is analyzed.

More about the Grassmann tensor renormalization group

Journal of High Energy Physics, 2021
We derive a general formula of the tensor network representation for d-dimensional lattice fermions with ultra-local interactions, including Wilson fermions, staggered fermions, and domain-wall fermions.

Stochastic computation of g − 2 in QED

Journal of High Energy Physics, 2021
We perform a numerical computation of the anomalous magnetic moment (g − 2) of the electron in QED by using the stochastic perturbation theory. Formulating QED on the lattice, we develop a method to calculate the coefficients of the perturbative series ...
