A bstract There are two well-known approaches to studying nonperturbative aspects of
quantum mechanical systems: saddle point analysis of the partition functions in Euclidean …

A bstract We make use of Borel resummation to extract the exact time dependence from the
divergent series found in the context of stochastic inflation. Correlation functions of self …

We investigate the implications of coupling a topological quantum field theory (TQFT) to
Yang-Mills theory with $ SU (N) $ gauge group in the context of the IR-renormalon problem …

We study a resurgence structure of a quantum field theory with a phase transition to uncover
relations between resurgence and phase transitions. In particular, we focus on three …

It was conjectured that bions, semi-classical objects found in a compactified spacetime, are
responsible for the cancellation of the so-called renormalon ambiguities. Contrary to the …

We study a resurgence structure of a quantum field theory with a phase transition to uncover
relations between resurgence and phase transitions. In particular, we focus on three …

The quantum vacuum (Casimir) energy arising from noninteracting massless quanta is
known to induce a long-range force, while decays exponentially for massive fields and …

We present additional observations to previous studies on the infrared (IR) renormalon in
QCD (adj.), the gauge theory with-flavor adjoint Weyl fermions on with the twisted boundary …

A bstract We investigate the lattice ℂP N− 1 sigma model on\({S} _s^ 1\)(large)×\({S} _ {\tau}^
1\)(small) with the ℤ N symmetric twisted boundary condition, where a sufficiently large ratio …

A bstract The resurgence structure of the 2d O (N) sigma model at large N is studied with a
focus on an IR momentum cutoff scale a that regularizes IR singularities in the semiclassical …
