Quantum Mechanics, Random Matrices and BMN Gauge Theory
C. Kristjansen
We review how the identification of gauge theory operators representing string states in the pp-wave/BMN correspondence and their associated anomalous dimension reduces to the dete…
BMN Gauge Theory as a Quantum Mechanical System
N. Beisert, C. Kristjansen, J. Plefka +1
We rigorously derive an effective quantum mechanical Hamiltonian from N=4 gauge theory in the BMN limit. Its eigenvalues yield the exact one-loop anomalous dimensions of scalar two…
Generalized Lorentzian Triangulations and the Calogero Hamiltonian
P. Di Francesco, E. Guitter, C. Kristjansen
We introduce and solve a generalized model of 1+1D Lorentzian triangulations in which a certain subclass of outgrowths is allowed, the occurrence of these being governed by a coupl…
On the relation between Euclidean and Lorentzian 2D quantum gravity
J. Ambjorn, J. Correia, C. Kristjansen +1
Starting from 2D Euclidean quantum gravity, we show that one recovers 2D Lorentzian quantum gravity by removing all baby universes. Using a peeling procedure to decompose the discr…
Integrable 2D Lorentzian Gravity and Random Walks
P. Di Francesco, E. Guitter, C. Kristjansen
We introduce and solve a family of discrete models of 2D Lorentzian gravity with higher curvature, which possess mutually commuting transfer matrices, and whose spectral parameter…
Hamiltonian Cycles on Random Eulerian Triangulations
E. Guitter, C. Kristjansen, J. L. Nielsen
A random Eulerian triangulation is a random triangulation where an even number of triangles meet at any given vertex. We argue that the central charge increases by one if the fully…
