A PERSPECTIVE ON BLACK HOLE HORIZONS FROM THE QUANTUM CHARGED PARTICLE

3 December 2014

Time: 4:01pm
Venue: Room G. O. Jones 516
Series: The London Relativity and Cosmology Seminar
Speaker: Jose Luis Jaramillo
Abstract: We point out a structural similarity between the characterization
of black hole apparent horizons as stable marginally outer trapped
surfaces (MOTS) and the quantum description of a non-relativistic
charged particle moving in given magnetic and electric fields on a
closed surface. Specifically, the MOTS-spectral problem corresponds to
a stationary quantum particle with a formal fine-structure constant
αα of negative sign. Such analogy may provide clues to the study
of the spectrum of the (non-selfadjoint) MOTS-stability operator
in comparison with the (selfadjoint) Hamiltonian of the quantum
charged particle. Moreover, this perspective might open an avenue
to the spinorial treatment of apparent horizon (MOTS-)stability and to
the introduction of semiclassical tools to explore some of the
qualitative aspects of the black hole spectral problem.
