Pion physics in two flavor strong coupling lattice QED
D. J. Cecile
We consider the lattice field theory involving two flavors of staggered quarks which interact with gauge fields in the strong coupling limit. For massless quarks, this the…
Effects of the anomaly on the QCD chiral phase transition
Shailesh Chandrasekharan, Abhijit C. Mehta
We study a lattice field theory described by two flavors of massless staggered fermions interacting with U(1) gauge fields in the strong coupling limit. We show that the lattice mo…
Flavor Twisted Boundary Conditions, Pion Momentum, and the Pion Electromagnetic Form Factor
F. -J. Jiang, B. C. Tiburzi
We investigate the utility of partially twisted boundary conditions in lattice calculations of meson observables. For dynamical simulations, we show that the pion dispersion relati…
Anomalous superfluidity in 2+1 dimensional two-color lattice QCD
Shailesh Chandrasekharan
We study thermodynamics of strongly coupled lattice QCD with colors of staggered fermions in dimensions. The partition function of this model can be written elegantly…
Flavor Twisted Boundary Conditions and Isovector Form Factors
Brian C. Tiburzi
We use vector flavor symmetry to relate form factors of isospin changing operators to isovector form factors. Flavor twisted boundary conditions in lattice QCD thus allow isovector…
Electromagnetic and spin polarisabilities in lattice QCD
W. Detmold, B. C. Tiburzi, A. Walker-Loud
We discuss the extraction of the electromagnetic and spin polarisabilities of nucleons from lattice QCD. We show that the external field method can be used to measure all the elect…
