Quasinormal modes in the background of charged Kaluza-Klein black hole with squashed horizons

We study the scalar perturbation in the background of the charged Kaluza-Klein black holes with squashed horizons. We find that the position of infinite discontinuities of the heat capacities can be reflected in quasinormal spectrum. This shows the possible non-trivial relation between the thermodynamical and dynamical properties of black holes. (c) 2008 Elsevier B.V. All rights reserved.
