Resurgence theory, ghost-instantons, and analytic continuation of path integrals

A bstractA general quantum mechanical or quantum field theoretical system in the path integral formulation has both real and complex saddles (instantons and ghost-instantons). Resurgent asymptotic

Quantum geometry of resurgent perturbative/nonperturbative relations

A bstractFor a wide variety of quantum potentials, including the textbook ‘instanton’ examples of the periodic cosine and symmetric double-well potentials, the perturbative data coming from

Resurgence in sine-Gordon quantum mechanics: exact agreement between multi-instantons and uniform WKB

A bstractWe compute multi-instanton amplitudes in the sine-Gordon quantum mechanics (periodic cosine potential) by integrating out quasi-moduli parameters corresponding to separations of instantons

Instanton Effects and Quantum Spectral Curves

We study a spectral problem associated to the quantization of a spectral curve arising in local mirror symmetry. The perturbative WKB quantization condition is determined by the quantum periods, or

Instantons in the Hofstadter butterfly: difference equation, resurgence and quantum mirror curves

A bstractWe study the Harper-Hofstadter Hamiltonian and its corresponding non-perturbative butterfly spectrum. The problem is algebraically solvable whenever the magnetic flux is a rational multiple

Semiclassical Trans-Series from the Perturbative Hopf-Algebraic Dyson-Schwinger Equations: phi3 QFT in 6 Dimensions

We analyze the asymptotically free massless scalar φ quantum field theory in 6 dimensions, using resurgent asymptotic analysis to find the trans-series solutions which yield the non-perturbative

Summation of divergent series by order dependent mappings: Application to the anharmonic oscillator and critical exponents in field theory

We study numerically a method of summation of divergent series based on an order dependent mapping. We consider the example of a simple integral, of the ground‐state energy of the anharmonic

Instantons in gauge theories

This volume is a compilation of works which, taken together, give a complete and consistent presentation of instanton calculus in non-Abelian gauge theories, as it exists now. Some of the papers

Expansion around instantons in quantum mechanics

We calculate numerically a few terms of the corrections to the large‐order behavior of the ground state energy of the O(N) anharmonic oscillator by analyzing the perturbation series. We then generate

Perturbation theory at large orders for a potential with degenerate minima

Perturbation theory at large orders for a potential with degenerate minima differs from other cases discussed in previous works. The pseudoparticle which interpolates between the two classical minima

Quantum field theory

This book is a modern pedagogic introduction to the ideas and techniques of quantum field theory. After a brief overview of particle physics and a survey of relativistic wave equations and Lagrangian
