Summary: | Nuclear Physics B, 1008 (2024) 116683 In this paper, we study the topological properties of five-dimensional
rotating charged black holes in different ensembles.The topological numbers for
the black holes are gotten in the grand canonical and canonical ensembles,
which are 1. When the charge and cosmological constant disappear, their
topological numbers are 0. When the pressure is lower than the critical
pressure, the phase transition exists in the canonical ensemble. However, the
phase transition also exists in the grand canonical ensemble when the pressure
is higher than the critical pressure and two independent rotational parameters
are $a=1$ and $b=-1$. This may be due to the fact that the values of the
rotational parameters change the supersymmetry of the black hole and lead to
the phase transition. |
