Nonabelian Monopoles and the Vortices that Confine Them
Roberto Auzzi, Stefano Bolognesi, Jarah Evslin +1
Nonabelian magnetic monopoles of Goddard-Nuyts-Olive-Weinberg type have recently been shown to appear as the dominant infrared degrees of freedom in a class of softly broken ${\cal…
On orbifold theory and N=2, D=5 gauged supergravity
Yin Lin
We have studied the most general N=2 supergravity in five dimensions in context with the orbifold theory based on . Various ways to treat the supersymmetry with…
Nonabelian Bundle Gerbes, their Differential Geometry and Gauge Theory
Paolo Aschieri, Luigi Cantini, Branislav Jurco
Bundle gerbes are a higher version of line bundles, we present nonabelian bundle gerbes as a higher version of principal bundles. Connection, curving, curvature and gauge transform…
On the Topology and Flux of T-Dual Manifolds
Peter Bouwknegt, Jarah Evslin, Varghese Mathai
We present a general formula for the topology and H-flux of the T-dual of a type two compactification. Our results apply to T-dualities with respect to any free circle action. In p…
From E_8 to F via T
Jarah Evslin
We argue that T-duality and F-theory appear automatically in the E_8 gauge bundle perspective of M-theory. The 11-dimensional supergravity four-form determines an E_8 bundle. If we…
The tetrahedron graph in Liouville theory on the pseudosphere
Pietro Menotti, Erik Tonni
We compute analytically the tetrahedron graph in Liouville theory on the pseudosphere. The result allows to extend the check of the bootstrap formula of Zamolodchikov and Zamolodch…
k-string tensions in the 3-d SU(N) Georgi-Glashow model
Dmitri Antonov, Luigi Del Debbio
The classic argument by Polyakov showing that monopoles produce confinement in the Higgs phase of the Georgi-Glashow model is generalized to study the spectrum of k-strings. We fin…
Consistent irrelevant deformations of interacting conformal field theories
Damiano Anselmi
I show that under certain conditions it is possible to define consistent irrelevant deformations of interacting conformal field theories. The deformations are finite or have a uniq…
Finiteness of quantum gravity coupled with matter in three spacetime dimensions
Damiano Anselmi
As it stands, quantum gravity coupled with matter in three spacetime dimensions is not finite. In this paper I show that an algorithmic procedure that makes it finite exists, under…
Renormalization of quantum gravity coupled with matter in three dimensions
Damiano Anselmi
In three spacetime dimensions, where no graviton propagates, pure gravity is known to be finite. It is natural to inquire whether finiteness survives the coupling with matter. Stan…
Nonabelian Superconductors: Vortices and Confinement in SQCD
Roberto Auzzi, Stefano Bolognesi, Jarah Evslin +2
We study nonabelian vortices (flux tubes) in SU(N) gauge theories, which are responsible for the confinement of (nonabelian) magnetic monopoles. In particular a detailed analysis i…
T-Duality: Topology Change from H-flux
P. Bouwknegt, J. Evslin, V. Mathai
T-duality acts on circle bundles by exchanging the first Chern class with the fiberwise integral of the H-flux, as we motivate using E_8 and also using S-duality. We present known…
Calculating Gluino Condensates in SYM from Seiberg-Witten Curves
K. Konishi, A. Ricco
We determine the gluino condensate $< \Tr λ^2 >$ in the pure super Yang-Mills theory (SYM) for the classical gauge groups , , and …
A Torsion Correction to the RR 4-Form Fieldstrength
Jarah Evslin
The shifted quantization condition of the M-theory 4-form G_4 is well-known. The most naive generalization to type IIA string theory fails, an orientifold counterexample was found…
SU(N) fundamental and adjoint confining strings
Dmitri Antonov
String representations of the Wilson loop are constructed in the SU(N)-version of compact QED in three and four dimensions. This is done exactly in the case of the fundamental Wils…
Reflection-Transmission Algebras
M. Mintchev, E. Ragoucy, P. Sorba
Inspired by factorized scattering from delta-type impurities in (1+1)-dimensional space-time, we propose and analyse a generalization of the Zamolodchikov-Faddeev algebra. Distingu…
SUSY 3D Georgi-Glashow model at finite temperature
D. Antonov, A. Kovner
We study the finite-temperature properties of the supersymmetric version of (2+1)D Georgi-Glashow model. As opposed to its nonsupersymmetric counterpart, the parity symmetry in thi…
Twisted K-Theory from Monodromies
Jarah Evslin
RR fluxes representing different cohomology classes may correspond to the same twisted K-theory class. We argue that such fluxes are related by monodromies, generalizing and someti…
Charge density and electric charge in quantum electrodynamics
G. Morchio, F. Strocchi
The convergence of integrals over charge densities is discussed in relation with the problem of electric charge and (non-local) charged states in Quantum Electrodynamics (QED). Del…
