  - "Particle creation terms in quantum Hamiltonians are usually ultraviolet\r\ndivergent
    and thus mathematically ill defined. A rather novel way of solving\r\nthis problem
    is based on imposing so-called interior-boundary conditions on the\r\nwave function.
    Previous papers showed that this approach works in the\r\nnon-relativistic regime,
    but particle creation is mostly relevant in the\r\nrelativistic case after all.
    In flat relativistic space-time (that is,\r\nneglecting gravity), the approach
    was previously found to work only for certain\r\nsomewhat artificial cases. Here,
    as a way of taking gravity into account, we\r\nconsider curved space-time, specifically
    the super-critical\r\nReissner-Nordstr\\\"om space-time, which features a naked
    timelike singularity.\r\nWe find that the interior-boundary approach works fully
    in this setting; in\r\nparticular, we prove rigorously the existence of well-defined,
    self-adjoint\r\nHamiltonians with particle creation at the singularity, based
    on\r\ninterior-boundary conditions. We also non-rigorously analyze the asymptotic\r\nbehavior
    of the Bohmian trajectories and construct the corresponding Bohm-Bell\r\nprocess
    of particle creation, motion, and annihilation. The upshot is that in\r\nquantum
    physics, a naked space-time singularity need not lead to a breakdown of\r\nphysical
    laws, but on the contrary allows for boundary conditions governing\r\nwhat comes
    out of the singularity and thereby removing the ultraviolet\r\ndivergence.@eng"
