Effect of Schwinger pair production on the evolution of the Hubble constant in de~Sitter spacetime
Ehsan Bavarsad, Sang Pyo Kim, Clément Stahl +1
In this proceeding we consider a massive charged scalar field in a uniform electric field background in a de~Sitter spacetime (dS). We compute the in-vacuum expectation value of th…
Astrophysics in Strong Electromagnetic Fields and Laboratory Astrophysics
Sang Pyo Kim
Recent observations of gravitational waves from binary mergers of black holes or neutron stars and the rapid development of ultra-intense lasers lead strong field physics to a fron…
Equivalence between the phase-integral and worldline-instanton methods
Sang Pyo Kim, Don N. Page
The phase-integral and worldline-instanton methods are two widely used methods to calculate Schwinger pair-production densities in electric fields of fixed direction that depend on…
Charge Emission from Near-Extremal Charged Black Holes
Chiang-Mei Chen, Sang Pyo Kim, Jia-Rui Sun
Using the symmetry of the near-horizon geometry and applying quantum field theory of a complex scalar field, we study the spontaneous pair production of charged scalars from near-e…
Simulation of Quantum Universe
Sang Pyo Kim
Quantum simulation provides quantum systems under study with analogous controllable quantum systems and has wide applications from condensed-matter physics to high energy physics a…
