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.

One-thimble regularisation of lattice field theories: Is it only a dream? [PDF]
, 2020 Lefschetz thimbles regularisation of (lattice) field theories was put forward as a possible solution to the sign problem. Despite elegant and conceptually simple, it has many subtleties, a major one boiling down to a plain question: how many thimbles ...

The pseudoparticle approach for solving path integrals in gauge theories [PDF]
, 2005 We present a numerical technique for calculating path integrals in non-compact U(1) and SU(2) gauge theories. The gauge fields are represented by a superposition of pseudoparticles of various types with their amplitudes and color orientations as degrees ...

Bootstrap, Markov Chain Monte Carlo, and LP/SDP hierarchy for the lattice Ising model
Journal of High Energy Physics, 2023 Bootstrap is an idea that imposing consistency conditions on a physical system may lead to rigorous and nontrivial statements about its physical observables. In this work, we discuss the bootstrap problem for the invariant measure of the stochastic Ising

Renormalisation of composite operators in lattice QCD: perturbative versus nonperturbative [PDF]
, 2010 The perturbative and nonperturbative renormalisation of quark-antiquark operators in lattice QCD with two flavours of clover fermions is investigated within the research programme of the QCDSF collaboration.

Scale setting for large-N SUSY Yang-Mills on the lattice
Journal of High Energy Physics, 2022 In this paper we study the large N limit of four-dimensional Supersymmetric Yang-Mills on the lattice using twisted reduced models. We have generated configurations with dynamical massive gluinos and various lattice ’t Hooft couplings, and verified that ...

Lattice field theory results for hybrid static potentials at short quark-antiquark separations and their parametrization [PDF]
, 2022 We present SU(3) lattice Yang-Mills data for hybrid static potentials from five ensembles with different small lattice spacings and the corresponding parametrizations for quark-antiquark separations $0.08\,\text{fm} \le r \le 1.12\,\text{fm}$.

Analogues of Non-Gibbsianness in Joint Measures of Disordered Mean Field Models [PDF]
, 2002 It is known that the joint measures on the product of spin-space and disorder space are very often non-Gibbsian measures, for lattice systems with quenched disorder, at low temperature.

Improved lattice method for determining entanglement measures in SU(N) gauge theories
, 2022 The determination of entanglement measures in SU(N) gauge theories is a non-trivial task. With the so-called "replica trick", a family of entanglement measures, known as "Rényi entropies", can be determined with lattice Monte Carlo.

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics [PDF]
, 2022 Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...
