Cheshire Cat resurgence, Self-resurgence and Quasi-Exact Solvable Systems
Can Kozçaz, Tin Sulejmanpasic, Yuya Tanizaki +1
We explore a one parameter -deformation of the quantum-mechanical Sine-Gordon and Double-Well potentials which we call the Double Sine-Gordon (DSG) and the Tilted Double Well (T…
Global symmetries, volume independence and continuity
Tin Sulejmanpasic
We discuss quantum field theories with global and symmetries for which the temporal direction is compactified on a circle of size with periodicity of fields up t…
Deconstructing zero: resurgence, supersymmetry and complex saddles
Gerald V. Dunne, Mithat Unsal
We explain how a vanishing, or truncated, perturbative expansion, such as often arises in semi-classically tractable supersymmetric theories, can nevertheless be related to fluctua…
Aspects of Perturbation theory in Quantum Mechanics: The BenderWu Mathematica package
Tin Sulejmanpasic, Mithat Ünsal
We discuss a general setup which allows the study of the perturbation theory of an arbitrary, locally harmonic 1D quantum mechanical potential as well as its multi-variable (many-b…
Confinement in the bulk, deconfinement on the wall: infrared equivalence between compactified QCD and quantum magnets
Tin Sulejmanpasic, Hui Shao, Anders W. Sandvik +1
In a spontaneously dimerized quantum antiferromagnet, spin-1/2 excitations (spinons) are confined in pairs by strings akin to those confining quarks in non-abelian gauge theories.…
Chiral Lagrangian from Duality and Monopole Operators in Compactified QCD
Aleksey Cherman, Thomas Schaefer, Mithat Unsal
We show that there exists a special compactification of QCD on in which the theory has a domain where continuous chiral symmetry breaking is analytically…
WKB and Resurgence in the Mathieu Equation
Gerald V. Dunne, Mithat Unsal
In this paper, based on lectures by the authors at the May 2015 workshop {\it Resurgence, Physics and Numbers}, at the Centro di Ricerca Matematica Ennio De Giorgio of the Scuola N…
New Methods in QFT and QCD: From Large-N Orbifold Equivalence to Bions and Resurgence
Gerald V. Dunne, Mithat Unsal
We present a broad conceptual introduction to some new ideas in non-perturbative QFT. The large- orbifold-orientifold equivalence connects a natural large- limit of QCD to QC…
