Graphene, Lattice Field Theory and Symmetries [PDF]
, 2011 Borrowing ideas from tight binding model, we propose a board class of lattice field models that are classified by non simply laced Lie algebras. In the case of AN − 1 ≃ su(N) series, we show that the couplings between the quantum states living at the ...

Study of compact abelian lattice gauge theories [PDF]
arXiv, 2000 This is a review, intended for lattice nonspecialists, of the studies of the compact abelian gauge theories on the lattice performed by the Aachen lattice field theory group. We discuss in particular the pure compact QED and a U(1) lattice gauge theory with charged scalar and fermion fields in four and three dimensions.

Muon Spin Rotation and the Vortex Lattice in Superconductors [PDF]
, 2008 The magnetic field probability P(B) is calculated from the Ginzburg-Landau theory for various lattices of vortex lines in type-II superconductors: Ideal triangular lattices, lattices with various shear strains and with a super lattice of vacancies, and lattices of short vortices in films whose magnetic field ''mushrooms'' near the surface.

The dynamics of zero modes in lattice gauge theory — difference between SU(2) and SU(3) in 4D
Journal of High Energy Physics, 2023 The dynamics of zero modes in gauge theory is highly nontrivial due to its nonperturbative nature even in the case where the other modes can be treated perturbatively. One of the related issues concerns the possible instability of the trivial vacuum A μ (

Lattice regularisation of a non-compact boundary conformal field theory
Journal of High Energy Physics, 2021 Non-compact Conformal Field Theories (CFTs) are central to several aspects of string theory and condensed matter physics. They are characterised, in particular, by the appearance of a continuum of conformal dimensions.

Spinor class fields for sheaves of lattices [PDF]
arXiv, 2010 We extend the theory of spinor class field and representation fields previously defined for lattices over the ring of integers of a number field to both, lattices over the coordinate ring of a smooth irreducible affine curve over a finite field, and sheaves of lattices over the structure sheaf of an irreducible smooth projective curve over a finite ...

Regularization methods for Nuclear Lattice Effective Field Theory
Physics Letters B, 2015 We investigate Nuclear Lattice Effective Field Theory for the two-body system for several lattice spacings at lowest order in the pionless as well as in the pionful theory.

Physical Review Research, 2020 We study a three-dimensional chiral second-order topological insulator (SOTI) subject to a magnetic field. Via its gauge field, the applied magnetic field influences the electronic motion on the lattice, and via the Zeeman effect, the field influences ...
