Notes on Quasinormal Modes of charged de Sitter Blackholes from Quiver Gauge Theories



Summary

This study uses the connection formula for ordinary differential equations with 5 and 6 regular singularities to compute quasinormal modes of charged de Sitter blackholes from quiver gauge theories.

Highlights

  • The connection formula for ODEs with 5 and 6 regular singularities is generalized.
  • Quasinormal modes of Reissner-Nordström de Sitter blackholes are computed using the connection formula.
  • Analytic expressions for photon-sphere modes, dS modes, and near-extremal modes are obtained.
  • The connection formula is tested against numerical results from the QNMspectral package.
  • The method is also applied to non-scalar perturbations in RN-dS blackholes.
  • The dS-Kerr-Newman blackhole and 6-pt BPZ equation are discussed in appendices.
  • The study provides a new approach to computing quasinormal modes using gauge theories.

Key Insights

  • The connection formula provides a systematic way to write down the connection coefficients for ODEs with regular singularities, which can be used to compute quasinormal modes of blackholes.
  • The analytic expressions for quasinormal modes obtained from the connection formula match well with numerical results, especially for small Q/M and large ΛM2.
  • The connection formula approach can be used to study quasinormal modes of blackholes with different charges and rotations, providing a new tool for understanding blackhole physics.
  • The study demonstrates the power of gauge theories in computing quasinormal modes of blackholes, which can be used to study the AdS/CFT correspondence and the holographic principle.
  • The connection formula can be used to study the strong cosmic censorship problem in de Sitter blackholes, which is an important problem in theoretical physics.
  • The study provides a new approach to computing quasinormal modes using gauge theories, which can be used to study the properties of blackholes and the behavior of matter in extreme environments.
  • The connection formula can be used to study the perturbations of blackholes with different charges and rotations, providing a new tool for understanding blackhole physics.
