Spontaneous Parity Violation
P. R. Crompton
We disprove the Vafa-Witten theorem on the impossibility of spontaneously breaking parity in vector-like gauge field theories, identifying a mechanism driven by quantum fluctuation…
Asymptotics of the Infrared
P. R. Crompton
We follow recent formulations of dimensionally reduced loop operators for quantum field theories and exact representations of probabilistic lattice dynamics to identify a new schem…
Finite Size Scaling, Fisher Zeroes and N=4 Super Yang-Mills
P. R. Crompton, W. Janke, Z. X. Xu +1
We investigate critical slowing down in the local updating continuous-time Quantum Monte Carlo method by relating the finite size scaling of Fisher Zeroes to the dynamically genera…
Low-Lying Nucleons from Chirally Improved Fermions
D. Broemmel, P. R. Crompton, C. Gattringer +4
We report on our preliminary results on the low-lying excited nucleon spectra which we obtain through a variational basis formed with three different interpolators.
