Four-dimensional graphene and chiral fermions
Michael Creutz
Motivated by the description of the graphene electronic structure in terms of the relativistic Dirac equation, a generalization to four dimensions yields a strictly local fermion a…
The 't Hooft vertex revisited
Michael Creutz
In 1976 't Hooft introduced an elegant approach towards understanding the physical consequences of the topological structures that appear in non-Abelian gauge theories. These effec…
Why rooting fails
Michael Creutz
I explore the origins of the unphysical predictions from rooted staggered fermion algorithms. Before rooting, the exact chiral symmetry of staggered fermions is a flavored symmetry…
Effective potentials, thermodynamics, and twisted mass quarks
Michael Creutz
Using effective Lagrangian arguments, I explore the qualitative behavior expected at finite temperature for two flavor lattice QCD formulated with Wilson fermions and a twisted mas…
Chiral anomalies and rooted staggered fermions
Michael Creutz
A popular approximation in lattice gauge theory is an extrapolation in the number of fermion species away from the four fold degeneracy natural with the staggered fermion formulati…
