Abelian monopole condensation in lattice gauge theories [PDF]
, 1999 We investigate the dynamics of lattice gauge theories in an Abelian monopole background field. By means of the gauge-invariant lattice Schrodinger functional we study the Abelian monopole condensation in U(1) lattice gauge theory at zero temperature and ...

Quantum Finite Elements for Lattice Field Theory [PDF]
, 2016 Viable non-perturbative methods for lattice quantum field theories on curved manifolds are difficult. By adapting features from the traditional finite element methods (FEM) and Regge Calculus, a new simplicial lattice Quantum Finite Element (QFE ...

Pion-less effective field theory for atomic nuclei and lattice nuclei [PDF]
Physical Review C, 2017 We compute the medium-mass nuclei 16O and 40Ca using pion-less effective field theory (EFT) at next-to-leading order (NLO). The low-energy coefficients of the EFT Hamiltonian are adjusted to experimental data for nuclei with mass numbers A=2 and 3, or ...

Quark number susceptibility of high temperature and finite density QCD [PDF]
, 2007 We utilize lattice simulations of the dimensionally reduced effective field theory (EQCD) to determine the quark number susceptibility of QCD at high temperature ($T>2T_c$). We also use analytic continuation to obtain results at finite density.

The Tjon band in Nuclear Lattice Effective Field Theory [PDF]
European Physical Journal A, 2018 .We explore the lattice spacing dependence in Nuclear Lattice Effective Field Theory for few-body systems up to next-to-next-to leading order in chiral effective field theory including all isospin breaking and electromagnetic effects, the complete two ...

Relativistic-invariant formulation of the NREFT three-particle quantization condition
Journal of High Energy Physics, 2022 A three-particle quantization condition on the lattice is written down in a manifestly relativistic-invariant form by using a generalization of the non-relativistic effective field theory (NREFT) approach.

Lattice effective field theory for nuclei from A = 4 to A = 28 [PDF]
, 2013 We present an overview of the extension of Nuclear Lattice Effective Field Theory simulations to the regime of medium-mass nuclei. We focus on the determination of the ground-state energies of the alpha nuclei $^{16}$O, $^{20}$Ne, $^{24}$Mg and $^{28}$Si

Lattice improvement in lattice effective field theory [PDF]
European Physical Journal A, 2018 .Lattice calculations using the framework of effective field theory have been applied to a wide range of few-body and many-body systems. One of the challenges of these calculations is to remove systematic errors arising from the nonzero lattice spacing ...

Journal of High Energy Physics, 2019 There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlation function and the HAL QCD method which extracts observables from the non-local potential ...
