What is QFT? Resurgent trans-series, Lefschetz thimbles, and new exact saddles
Gerald V. Dunne, Mithat Unsal
This is an introductory level review of recent applications of resurgent trans-series and Picard-Lefschetz theory to quantum mechanics and quantum field theory. Resurgence connects…
Worldline Approach to Chiral Fermions
Kurt Langfeld, Gerald Dunne, Holger Gies +1
We propose to apply ``worldline numerics'' to a numerical calculation of quark determinants. The Gross-Neveu model with a U(1) chiral symmetry is considered as a first test. The wo…
Comparison of |Q|=1 and |Q|=2 gauge-field configurations on the lattice four-torus
Sundance O. Bilson-Thompson, Derek B. Leinweber, Anthony G. Williams +1
It is known that exactly self-dual gauge-field configurations with topological charge |Q|=1 cannot exist on the untwisted continuum 4-torus. We explore the manifestation of this re…
