Machine learning phases of an Abelian gauge theory
Jhao-Hong Peng, Yuan-Heng Tseng, Fu-Jiun Jiang
The phase transition of the two-dimensional quantum link model on the triangular lattice is investigated by employing a supervised neural network (NN) consisting of only one…
Nematic Confined Phases in the Quantum Link Model on a Triangular Lattice: An Opportunity for Near-Term Quantum Computations of String Dynamics on a Chip
D. Banerjee, S. Caspar, F. -J. Jiang +2
The quantum link model on the triangular lattice has two rotation-symmetry-breaking nematic confined phases. Static external charges are connected by confining strings consi…
Crystalline Confinement
D. Banerjee, P. Widmer, F. -J. Jiang +1
We show that exotic phases arise in generalized lattice gauge theories known as quantum link models in which classical gauge fields are replaced by quantum operators. While these q…
Axial and electromagnetic observables of hyperons in 2-flavor chiral perturbation theory
F. -J. Jiang, B. C. Tiburzi, A. Walker-Loud
Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties. Such expansions should exhibit marked improvement over the conventional three-flavo…

F. -J. Jiang, B. C. Tiburzi
Using flavor twisted boundary conditions, we study nucleon matrix elements of the vector current. We twist only the active quarks that couple to the current. Finite volume correcti…

Jie Hu, Fu-Jiun Jiang, Brian C. Tiburzi
We use chiral perturbation theory to study the extraction of pion electromagnetic polarizabilities from lattice QCD. Chiral extrapolation formulae are derived for partially quenche…
Current Renormalization in Finite Volume
Jie Hu, Fu-Jiun Jiang, Brian C. Tiburzi
For finite volume field theories with discrete translational invariance, conserved currents can be additively renormalized by infrared effects. We demonstrate this for pions using…

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…
