Wall-crossing, Hitchin Systems, and the WKB Approximation

- D. Gaiotto, G. Moore, A. Neitzke
- Physics, Mathematics
- 23 July 2009

We consider BPS states in a large class of d = 4,N = 2 eld theories, obtained by reducing six-dimensional (2; 0) superconformal eld theories on Riemann surfaces, with defect operators inserted at… Expand

Four-Dimensional Wall-Crossing via Three-Dimensional Field Theory

- D. Gaiotto, G. Moore, A. Neitzke
- Physics, Mathematics
- 29 July 2008

We give a physical explanation of the Kontsevich-Soibelman wall-crossing formula for the BPS spectrum in Seiberg-Witten theories. In the process we give an exact description of the BPS instanton… Expand

Framed BPS states

- D. Gaiotto, G. Moore, A. Neitzke
- Physics, Mathematics
- 1 June 2010

We consider a class of line operators in d = 4,N = 2 supersymmetric field theories which leave four supersymmetries unbroken. Such line operators support a new class of BPS states which we call… Expand

R-Twisting and 4d/2d Correspondences

- S. Cecotti, A. Neitzke, C. Vafa
- Physics
- 17 June 2010

We show how aspects of the R-charge of N=2 CFTs in four dimensions are encoded in the q-deformed Kontsevich-Soibelman monodromy operator, built from their dyon spectra. In particular, the monodromy… Expand

Spectral Networks

- D. Gaiotto, G. Moore, A. Neitzke
- Physics
- 21 April 2012

We introduce new geometric objects called spectral networks. Spectral networks are networks of trajectories on Riemann surfaces obeying certain local rules. Spectral networks arise naturally in… Expand

Topological M-theory as unification of form theories of gravity

- R. Dijkgraaf, S. Gukov, A. Neitzke, C. Vafa
- Physics, Mathematics
- 5 November 2004

We introduce a notion of topological M-theory and argue that it provides a unification of form theories of gravity in various dimensions. Its classical solutions involve G_2 holonomy metrics on… Expand

Twistors and black holes

- A. Neitzke, B. Pioline, S. Vandoren
- Physics, Mathematics
- 23 January 2007

Motivated by black hole physics in N=2, D=4 supergravity, we study the geometry of quaternionic-Kahler manifolds M obtained by the c-map construction from projective special Kahler manifolds M_s.… Expand

Asymptotic black hole quasinormal frequencies

- L. Motl, A. Neitzke
- Physics
- 23 January 2003

We give a new derivation of the quasinormal frequencies of Schwarzschild black holes in d>=4 and Reissner-Nordstrom black holes in d=4, in the limit of infinite damping. For Schwarzschild in d>=4 we… Expand

Argyres-Seiberg Duality and the Higgs Branch

- D. Gaiotto, A. Neitzke, Yuji Tachikawa
- Physics, Mathematics
- 25 October 2008

We demonstrate the agreement between the Higgs branches of two $${\mathcal{N}=2}$$ theories proposed by Argyres and Seiberg to be S-dual, namely the SU(3) gauge theory with six quarks, and the SU(2)… Expand

Line defects, tropicalization, and multi-centered quiver quantum mechanics

- Clay Córdova, A. Neitzke
- Physics, Mathematics
- 30 August 2013

A bstractWe study BPS line defects in N$$ \mathcal{N} $$ = 2 supersymmetric four-dimensional field theories. We focus on theories of “quiver type,” those for which the BPS particle spectrum can be… Expand
