QED vacuum nonlinearity in Laguerre-Gauss beams
Cesim K. Dumlu, Yoshihide Nakamiya, Kazuo A. Tanaka
We investigate in detail the stimulated photon emission in pulse-shaped Laguerre-Gauss beams of arbitrary mode decomposition within the framework of Euler-Heisenberg effective theo…
Stokes phenomenon and Hawking Radiation
Cesim K. Dumlu
We compute the semiclassical decay rate for Kerr black hole by deriving a one-way connection formula, relating the near horizon solution to the outgoing solution at infinity. In pa…
Hawking Radiation via Complex Geodesics
Cesim K. Dumlu
We describe in detail the quantum tunneling of massive particles from Kerr black hole by using complex trajectories, which are solutions to the Hamilton's equations of motion with…
Multidimensional quantum tunneling in the Schwinger effect
Cesim K. Dumlu
We study the Schwinger effect, in which the external field having a spatiotemporal profile creates electron-positron pairs via multidimensional quantum tunneling. Our treatment is…
Vacuum decay and the transmission resonances in space-dependent electric fields
Cesim K. Dumlu
We investigate the decay of quantum electrodynamical (QED) vacuum in arbitrary space-dependent electric fields. In particular, we analyze the resonance peaks of the positron emissi…
Complex Worldline Instantons and Quantum Interference in Vacuum Pair Production
Cesim K. Dumlu, Gerald V. Dunne
We describe in detail a physical situation in which instantons are necessarily complex, not just Wick rotations of classical solutions to Euclidean spacetime. These complex instant…
