Lattice meets lattice: Application of lattice cubature to models in lattice gauge theory [PDF]

open access: yesJournal of Computational Physics, 2021
High dimensional integrals are abundant in many fields of research including quantum physics. The aim of this paper is to develop efficient recursive strategies to tackle a class of high dimensional integrals having a special product structure with low order couplings, motivated by models in lattice gauge theory from quantum field theory.

Evolving Lattices for Analyzing Behavioral Dynamics of Characters in Literary Text

open access: yestripleC: Communication, Capitalism & Critique, 2011
This paper is about an application of rough set derived lattices in order to analyze the dynamics of literary text. Due to the double approximation nature of rough set theory, a pseudo-closure obtained from two different equivalence relations allows us ...

On the Lattice of Cotorsion Theories

open access: yesJournal of Algebra, 2001
We discuss the lattice of cotorsion theories for abelian groups. First we show that the sublattice of the well-studied rational cotorsion theories can be identified with the well-known lattice of types. Using a recently developed method for making Ext vanish we also prove that any power set together with the ordinary set inclusion (and thus any poset ...

The lowest Landau level in QCD

open access: yesEPJ Web of Conferences, 2017
The thermodynamics of Quantum Chromodynamics (QCD) in external (electro-)magnetic fields shows some unexpected features like inverse magnetic catalysis, which have been revealed mainly through lattice studies.

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

open access: yes, 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 ...

Finite-temperature SU(2) lattice gauge theory with dynamical fermions [PDF]

open access: yes, 1985
Heller UM, Karsch F. Finite-temperature SU(2) lattice gauge theory with dynamical fermions. Nuclear Physics, B. 1985;258(1):29-45.We study the influence of dynamical quarks on the deconfinement and chiral phase transitions of SU(2) lattice gauge theory ...

Eigenvalue spectrum and scaling dimension of lattice N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills

open access: yesJournal of High Energy Physics, 2021
We investigate the lattice regularization of N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory, by stochastically computing the eigenvalue mode number of the fermion operator.

Lattice Quantum ChromoDynamics with approximately chiral fermions [PDF]

open access: yes, 2008
In this work we present Lattice QCD results obtained by approximately chiral fermions. We use the CI fermions in the quenched approximation to investigate the excited baryon spectrum and to search for the Theta^+ pentaquark on the lattice. Furthermore we

On the Lattice Structure of Neutrosophic Open Sets for Risk Evaluation of Supply Chain Finance in International Cross-Border E-Commerce [PDF]

open access: yesNeutrosophic Sets and Systems
: In complex financial ecosystems, firms interact through asymmetric and uncertain relationships that classical models fail to capture adequately. With the increase of complexity of these ecosystems, standard topological and fuzzy approaches have become ...
