Exact Solution of Discrete Two-Dimensional R Gravity
We exactly solve a special matrix model of dually weighted planar graphs describing pure two-dimensional quantum gravity with a R interaction in order to study the intermediate regimes between the gravitating and flat metric. The flat space is modeled by a regular square lattice, while localized curvature is being introduced through defects of the lattice. No “flattening” phase transition is fo...
متن کاملDiscrete States in Two-Dimensional Quantum Gravity∗
We review the recent developments in the two-dimensional (super)gravity coupled to c(ĉ) ≤ 1 (super)conformal matter in the conformal gauge. Starting from a pedagogical account of the conformal anomaly in such a system, we show how the system is transformed into the representation in terms of the (free) Liouville field. Some perturbative justification is given to this procedure. The physical sta...
متن کاملExact solution of the discrete (1+1)-dimensional RSOS model
We present the solution of a linear restricted solid-on-solid (RSOS) model confined to a slit. We include a field-like energy, which equivalently weights the area under the interface, and also include independent interaction terms with both walls. This model can also be mapped to a lattice polymer model of Motzkin paths in a slit interacting with both walls including an osmotic pressure. This w...
متن کاملD=26 and Exact Solution to the Conformal-gauge Two-dimensional Quantum Gravity
The conformal-gauge two-dimensional quantum gravity is formulated in the framework of the BRS quantization and solved completely in the Heisenberg picture: All n-point Wightman functions are explicitly obtained. The eld-equation anomaly is shown to exist as in other gauges, but there is no other subtlety. At the critical dimension D = 26 of the bosonic string, the eld-equation anomaly is shown ...
متن کاملExact Solution for Relativistic Two-Body Motion in Dilaton Gravity
We present an exact solution to the problem of the relativistic motion of 2 point masses in (1 + 1) dimensional dilaton gravity. The motion of the bodies is governed entirely by their mutual gravitational influence, and the spacetime metric is likewise fully determined by their stress-energy. A Newtonian limit exists, and there is a static gravitational potential. Our solution gives the exact H...
