Monodromy defects in ABJM theory and integrability
Charlotte Kristjansen, Andrey Shusharin
We establish that supersymmetric monodromy defects in ABJM theory, also known as vortex loops, define integrable boundary states of the underlying alternating SU(4) spin chain. Exp…
The Concept of Time in 2D Quantum Gravity
J. Ambjorn, K. N. Anagnostopoulos, J. Jurkiewicz +1
We show that the ``time'' t_s defined via spin clusters in the Ising model coupled to 2d gravity leads to a fractal dimension d_h(s) = 6 of space-time at the critical point, as adv…
A Possible IIB Superstring Matrix Model with Euler Characteristic and a Double Scaling Limit
C. Kristjansen, P. Olesen
We show that a recently proposed Yang-Mills matrix model with an auxiliary field, which is a candidate for a non-perturbative description of type IIB superstrings, captures the Eul…
Phase Structure of the O(n) Model on a Random Lattice for n>2
B. Durhuus, C. Kristjansen
We show that coarse graining arguments invented for the analysis of multi-spin systems on a randomly triangulated surface apply also to the O(n) model on a random lattice. These ar…
Hermitian Matrix Model with Plaquette Interaction
L. Chekhov, C. Kristjansen
We study a hermitian -matrix model with plaquette interaction, . By means of a conformal transformation we rewrite the model as an model on a r…
More on the exact solution of the O(n) model on a random lattice and an investigation of the case |n|>2
B. Eynard, C. Kristjansen
For the model on a random lattice has critical points to which a scaling behaviour characteristic of 2D gravity interacting with conformal matter fields with $…
Exact Solution of the O(n) Model on a Random Lattice
B. Eynard, C. Kristjansen
We present an exact solution of the model on a random lattice. The coupling constant space of our model is parametrized in terms of a set of moment variables and the same ty…
Multi-loop correlators for rational theories of 2D gravity from the generalized Kontsevich models
C. Kristjansen
We introduce a parametrization of the coupling constant space of the generalized Kontsevich models in terms of a set of moments equivalent to those introduced recently in the conte…
