Characteristic Polynomials of Complex Random Matrix Models
G. Akemann, G. Vernizzi
We calculate the expectation value of an arbitrary product of characteristic polynomials of complex random matrices and their hermitian conjugates. Using the technique of orthogona…
Asymmetric Cosets
Thomas Quella, Volker Schomerus
The aim of this work is to present a general theory of coset models G/H in which different left and right actions of H on G are gauged. Our main results include a formula for their…
Spacetime Energy Decreases under World-sheet RG Flow
Michael Gutperle, Matthew Headrick, Shiraz Minwalla +1
We study renormalization group flows in unitary two dimensional sigma models with asymptotically flat target spaces. Applying an infrared cutoff to the target space, we use the Zam…
Are there really any AdS_2 branes in the euclidean (or not) AdS_3?
Benedicte Ponsot, Sebastian Silva
We do not find any AdS_2 branes, neither in the H_3^+ WZNW model nor the SL(2,R) WZNW model. We then reexamine the case of the branes that possess a su(2) symmetry: we speculate th…
Phase Structure of Supersymmetric Models at Finite Temperature
Moshe Moshe, Jean Zinn-Justin
We study O(N) symmetric supersymmetric models in three dimensions at finite temperature. These models are known to have an interesting phase structures. In particular, in the limit…
Conformal Field Theories of Stochastic Loewner Evolutions
Michel Bauer, Denis Bernard
Stochastic Loewner evolutions (SLE) are random growth processes of sets, called hulls, embedded in the two dimensional upper half plane. We elaborate and develop a relation between…
Cosmological Evolution of Brane World Moduli
Ph. Brax, C. van de Bruck, A. -C. Davis +1
We study cosmological consequences of non-constant brane world moduli in five dimensional brane world models with bulk scalars and two boundary branes. We focus on the case where t…
A comment on bouncing and cyclic branes in more than one extra-dimension
Ph. Brax, D. A. Steer
We argue that bouncing branes occur naturally when there is more than one extra-dimension. We consider three-branes embedded in space-times with a horizon and an isometry group SO(…
Microscopic universality of complex matrix model correlation functions at weak non-Hermiticity
G. Akemann
The microscopic correlation functions of non-chiral random matrix models with complex eigenvalues are analyzed for a wide class of non-Gaussian measures. In the large-N limit of we…
Custodial supersymmetry in non-supersymmetric quiver theories
Philippe Brax, Adam Falkowski, Zygmunt Lalak +1
We consider non-supersymmetric quiver theories obtained by orbifolding the N=4 supersymmetric U(K) gauge theory by a discrete Z_Γgroup embedded in the SU(4) R-symmetry group. We ex…
The solution of a chiral random matrix model with complex eigenvalues
G. Akemann
We describe in detail the solution of the extension of the chiral Gaussian Unitary Ensemble (chGUE) into the complex plane. The correlation functions of the model are first calcula…
Microscopic correlation functions for the QCD Dirac operator with chemical potential
G. Akemann
A chiral random matrix model with complex eigenvalues is solved as an effective model for QCD with non-vanishing chemical potential. We derive new matrix model correlation function…
Four--dimensional Gravity from Singular Spaces
P. Brax, C. van de Bruck, A. C. Davis +1
The modification to four--dimensional Einstein gravity at low energy in two brane models is investigated within supergravity in singular spaces. Using perturbation theory around a…
On Anomalies in Orbifold Theories
Luigi Pilo, Antonio Riotto
We study the issue of gauge invariance in five-dimensional theories compactified on an orbifold in the presence of an external U(1) g…
Wave function of the radion with a bulk scalar field
P. Brax, C. van de Bruck, A. C. Davis +1
The behaviour of the distance between two branes (the `radion') in a braneworld model with a bulk scalar field is investigated. We show that the BPS conditions of supergravity ensu…
Classical-to-critical crossovers from field theory
C. Bagnuls, C. Bervillier
We extent the previous determinations of nonasymptotic critical behavior of Phys. Rev B32, 7209 (1985) and B35, 3585 (1987) to accurate expressions of the complete classical-to-cri…
New Critical Matrix Models and Generalized Universality
G. Akemann, G. Vernizzi
We study a class of one-matrix models with an action containing nonpolynomial terms. By tuning the coupling constants in the action to criticality we obtain that the eigenvalue den…
