Transgressing the horizons: Time operator in twodimensional dilaton gravity
Abstract
We present a Dirac quantization of generic singlehorizon black holes in twodimensional dilaton gravity. The classical theory is first partially reduced by a spatial gauge choice under which the spatial surfaces extend from a black or white hole singularity to a spacelike infinity. The theory is then quantized in a metric representation, solving the quantum Hamiltonian constraint in terms of (generalized) eigenstates of the ADM mass operator and specifying the physical inner product by selfadjointness of a time operator that is affinely conjugate to the ADM mass. Regularity of the time operator across the horizon requires the operator to contain a quantum correction that distinguishes the future and past horizons and gives rise to a quantum correction in the hole's surface gravity. We expect a similar quantum correction to be present in systems whose dynamics admits black hole formation by gravitational collapse.

We present cosmological solutions for (1+3+n)dimensional steady state universe in dilaton gravity with an arbitrary dilaton coupling constant w and exponential dilaton selfinteraction potentials in the string frame. We focus particularly on the class in which the 3space expands with a time varying deceleration parameter. We discuss the number of the internal dimensions and the value of the dilaton coupling constant to determine the cases that are consistent with the observed universe and the primordial nucleosynthesis. The 3space starts with a decelerated expansion rate and evolves into accelerated expansion phase subject to the values of w and n, but endsmore »

Black hole physics from twodimensional dilaton gravity based on the SL(2,[ital R])/U(1) coset model
We analyze the quantum twodimensional dilaton gravity model, which is described by the SL(2,[ital R])/U(1) gauged WessZuminoWitten model deformed by a (1,1) operator. We show that the curvature singularity does not appear when the central charge [ital c][sub matter] of the matter fields is given by 22[lt][ital c][sub matter][lt]24. When 22[lt][ital c][sub matter][lt]24, the matter shock waves, whose energymomentum tensors are given by [ital T][sub matter][proportional to][delta]([ital x][sup +][minus][ital x][sub 0][sup +]), create a kind of wormholes, i.e., causally disconnected regions. Most of the quantum information in past null infinity is lost in future null infinity but the lost informationmore » 
Covariant effective action and oneloop renormalization of twodimensional dilaton gravity with fermionic matter
Twodimensional dilaton gravity interacting with a fourfermion model and scalars is investigated, all the coefficients of the Lagrangian being arbitrary functions of the dilaton field. The oneloop covariant effective action for twodimensional (2D) dilaton gravity with Majorana spinors (including the fourfermion interaction) is obtained, and the technical problems which appear in an attempt at generalizing such calculations to the case of the most general fourfermion model described by Dirac fermions are discussed. A solution to these problems is found, based on its reduction to the Majorana spinor case. The general covariant effective action for 2D dilaton gravity with the fourfermionmore » 
[ital N]=2 supersymmetry in twodimensional dilaton gravity
Actions for [ital D]=2, [ital N]=2 supergravity coupled to a scalar field are calculated, and it is shown that the most general powercounting renormalizable dilaton gravity action has an [ital N]=2 locally supersymmetric extension. The presence of chiral terms in the action leads one to hope that nonrenormalization theorems similar to those in global SUSY will apply; this would eliminate some of the renormalization ambiguities which plague ordinary bosonic (and [ital N]=1) dilaton gravity. To investigate this, the model is studied in the superconformal gauge, where it is found that one chiral term becomes nonchiral, so that only one termmore » 
Supersymmetry and positive energy in classical and quantum twodimensional dilaton gravity
An [ital N]=1 supersymmetric version of twodimensional dilaton gravity coupled to matter is considered. It is shown that the linear dilaton vacuum spontaneously breaks half the supersymmetries, leaving broken a linear combination of left and right supersymmetries which squares to time translations. Supersymmetry suggests a spinorial expression for the ArnowittDeserMisner energy [ital M], as found by Witten in fourdimensional general relativity. Using this expression it is proven that [ital M] is nonnegative for smooth initial data asymptotic (in both directions) to the linear dilaton vacuum, provided that the (not necessarily supersymmetric) matter stress tensor obeys the dominant energy condition.
