Resurgence theory, ghost-instantons, and analytic continuation of path integrals
Gokce Basar, Gerald V. Dunne, Mithat Unsal
A general quantum mechanical or quantum field theoretical system in the path integral formulation has both real and complex saddles (instantons and ghost-instantons). Resurgent asy…
Chiral and Gravitational Anomalies on Fermi Surfaces
Gokce Basar, Dmitri E. Kharzeev, Ismail Zahed
A Fermi surface threaded by a Berry phase can be described by the Wess-Zumino-Witten (WZW) term. After gauging, it produces a five-dimensional Chern-Simons term in the action. We s…
Large N Volume Independence and an Emergent Fermionic Symmetry
Gokce Basar, Aleksey Cherman, Daniele Dorigoni +1
Large-N volume independence in circle-compactified QCD with N_f \geq 1 adjoint Weyl fermions implies the absence of any phase transitions as the radius is dialed to arbitrarily sma…
Triangle anomaly in Weyl semi-metals
Gokce Basar, Dmitri E. Kharzeev, Ho-Ung Yee
Weyl semimetals possess massless chiral quasi-particles, and are thus affected by the triangle anomalies. We discuss the features of the chiral magnetic and chiral vortical effects…
