Resurgence and Holomorphy: From Weak to Strong Coupling
Aleksey Cherman, Peter Koroteev, Mithat Ünsal
We analyze the resurgence properties of finite-dimensional exponential integrals which are prototypes for partition functions in quantum field theories. In these simple examples, w…
Bose-Fermi Degeneracies in Large Adjoint QCD
Gokce Basar, Aleksey Cherman, David A. McGady
We analyze the large limit of adjoint QCD, an gauge theory with flavors of massless adjoint Majorana fermions, compactified on . We focus on the w…
Real-Time Feynman Path Integral Realization of Instantons
Aleksey Cherman, Mithat Unsal
In Euclidean path integrals, quantum mechanical tunneling amplitudes are associated with instanton configurations. We explain how tunneling amplitudes are encoded in real-time Feyn…
Casimir energy of confining large gauge theories
Gokce Basar, Aleksey Cherman, David A. McGady +1
Four-dimensional asymptotically-free large gauge theories compactified on have a weakly-coupled confining regime when is small compared to the str…
T-Reflection
Gokce Basar, Aleksey Cherman, David A. McGady +1
We point out the presence of a temperature-reflection (-reflection) symmetry for the partition functions of many physical systems. Without knowledge of the origin of…
Decoding perturbation theory using resurgence: Stokes phenomena, new saddle points and Lefschetz thimbles
Aleksey Cherman, Daniele Dorigoni, Mithat Unsal
Resurgence theory implies that the non-perturbative (NP) and perturbative (P) data in a QFT are quantitatively related, and that detailed information about non-perturbative saddle…
