The Devil Went Down to de Sitter: Divergent Effective Field Theory Expansions in Cosmology
Daniele Dorigoni, Laura Engelbrecht, Nadine Nussbaumer +1
Effective field theories (EFTs) in de Sitter space, and in accelerating cosmologies more generally, must capture phenomena absent in flat space, most notably long-range correlation…
Giant graviton integrated correlators at finite coupling and all orders in
Augustus Brown, Daniele Dorigoni, Congkao Wen
We study the giant graviton integrated correlator in SU super Yang-Mills at finite complexified coupling . Despite the formidable complexity arising from th…
Instanton Solutions from Abelian Sinh-Gordon and Tzitzeica Vortices
Felipe Contatto, Daniele Dorigoni
We study the Abelian Higgs vortex solutions to the sinh-Gordon equation and the elliptic Tzitzeica equation. Starting from these particular vortices, we construct solutions to the…
An Introduction to Resurgence, Trans-Series and Alien Calculus
Daniele Dorigoni
In these notes we give an overview of different topics in resurgence theory from a physics point of view, but with particular mathematical flavour. After a short review of the stan…
Intersecting Branes, Domain Walls and Superpotentials in 3d Gauge Theories
Daniele Dorigoni, David Tong
We revisit the Hanany-Witten brane construction of 3d gauge theories with N=2 supersymmetry. Instantons are known to generate a superpotential on the Coulomb branch of the theory.…
A ladder of topologically non-trivial non-BPS states
Daniele Dorigoni, Norman A. Rink
We consider a simple quiver gauge theory with gauge group U(r1) x U(r2) and a Higgs field in the bi-fundamental representation. The back-ground for this theory is a compact Kähler…
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…
Resurgence in QFT: Unitons, Fractons and Renormalons in the Principal Chiral Model
Aleksey Cherman, Daniele Dorigoni, Gerald V. Dunne +1
We explain the physical role of non-perturbative saddle points of path integrals in theories without instantons, using the example of the asymptotically free two-dimensional princi…
Vortex Motion on Surfaces of Small Curvature
Daniele Dorigoni, Maciej Dunajski, Nicholas S. Manton
We consider a single Abelian Higgs vortex on a surface Σ whose Gaussian curvature K is small relative to the size of the vortex, and analyse vortex motion by using geodesics on the…
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…
Large N and Bosonization in Three Dimensions
Aleksey Cherman, Daniele Dorigoni
Bosonization is normally thought of as a purely two-dimensional phenomenon, and generic field theories with fermions in D>2 are not expected be describable by local bosonic actions…
Non-Abelian monopole-vortex complex
Mattia Cipriani, Daniele Dorigoni, Sven Bjarke Gudnason +2
In the context of softly broken N=2 supersymmetric quantum chromodynamics (SQCD), with a hierarchical gauge symmetry breaking SU(N+1) -> U(N) -> 1, at scales v1 and v2, respectivel…
Non-Abelian Vortices without Dynamical Abelianization
Daniele Dorigoni, Kenichi Konishi, Keisuke Ohashi
Vortices carrying truly non-Abelian flux moduli, which do not dynamically reduce to Abelian vortices, are found in the context of softly-broken supersymmetric chromody…
