Comment on `One Loop Renormalization of Soliton Quantum Mass Corrections in 1+1 Dimensional Scalar Field Theory Models' (Phys. Lett. B542 (2002) 282 [hep-th/0206047])
A. Rebhan, P. van Nieuwenhuizen, R. Wimmer
We refute the claim that previous works on the one-loop quantum mass of solitons had incorrectly dropped a surface term from a partial integration. Rather, the paper quoted in the…
Non-existence of a dilaton gravity action for the exact string black hole
D. Grumiller, D. Vassilevich
We prove that no local diffeomorphism invariant two-dimensional theory of the metric and the dilaton without higher derivatives can describe the exact string black hole solution fo…
The Energy-Momentum Tensor in Noncommutative Gauge Field Models
J. M. Grimstrup, B. Kloiböck, L. Popp +3
We discuss the different possibilities of constructing the various energy-momentum tensors for noncommutative gauge field models. We use Jackiw's method in order to get symmetric a…
Bosonic vacuum wave functions from the BCS-type wave function of the ground state of the massless Thirring model
M. Faber, A. N. Ivanov
A BCS-type wave function describes the ground state of the massless Thirring model in the chirally broken phase. The massless Thirring model with fermion fields quantized in the ch…
Space/time noncommutative field theories and causality
H. Bozkaya, P. Fischer, H. Grosse +4
As argued previously, amplitudes of quantum field theories on noncommutative space and time cannot be computed using naive path integral Feynman rules. One of the proposals is to u…
Graded Poisson-Sigma Models and Dilaton-Deformed 2D Supergravity Algebra
L. Bergamin, W. Kummer
Fermionic extensions of generic 2d gravity theories obtained from the graded Poisson-Sigma model (gPSM) approach show a large degree of ambiguity. In addition, obstructions may red…
