We examine the two-dimensional spacetimes that emerge from string theory. We find all the solutions with no tachyons, and show that the only non-trivial solution is the black hole spacetime. We examine the role of duality in this picture. We then explore the thermodynamics of these solutions which is complicated by the fact that only in two spacetime dimensions is it impossible to redefine the dilaton field in terms of a canonical scalar field. Finally, we extend our analysis to the heterotic string, and briefly comment on exact, as opposed to perturbative, solutions.

    A triple-scaling limit of quantum gravity keeps black hole thermodynamics finite and reproduces the Hawking temperature.

  2. New analytic solutions of non-SUSY black branes in $10$-D heterotic supergravity and the phase transition

    hep-th 2025-12 unverdicted novelty 5.0 of 10

    New exact non-SUSY black brane solutions in 10D heterotic supergravity with two gauge charges show a spontaneous symmetry breaking and dynamical instability at low temperature that predicts additional black hole solutions.
