Small black holes on cylinders. (English) Zbl 1405.83030

Summary: We find the metric of small black holes on cylinders, i.e. neutral and static black holes with a small mass in d-dimensional Minkowski space times a circle. The metric is found using an ansatz for black holes on cylinders proposed in [the author and N. A. Obers, “Black holes on cylinders”, J. High Energy Phys. 2002, No. 5, 032, 62 p. (2002; doi:jhep052002032)]. We use the new metric to compute corrections to the thermodynamics which is seen to deviate from that of the \((d+1)\)-dimensional Schwarzschild black hole. Moreover, we compute the leading correction to the relative binding energy which is found to be non-zero. We discuss the consequences of these results for the general understanding of black holes and we connect the results to the phase structure of black holes and strings on cylinders.
