Reflection and transmission resonances and accuracy of the wkb method
Tritos Ngampitipan, Petarpa Boonserm
In this paper, we calculate the transmission and reflection amplitudes of wave functions for different potentials such as the delta function, the rectangular barrier, the Eckart po…
Bounding the greybody factors for the Reissner-Nordström black holes
Tritos Ngampitipan, Petarpa Boonserm
A black hole can emit radiation called Hawking radiation. Such radiation seen by an observer outside the black hole differs from the original radiation near the horizon of the blac…
Constraining transmission and reflection probabilities by using the Miller-Good transformation
Petarpa Boonserm, Matt Visser
Transmission through and reflection from a potential barrier, and the very closely related issue of particle production from a parametric resonance, are topics of considerable gene…
Bounds on variable-length compound jumps
Petarpa Boonserm, Matt Visser
In Euclidean space there is a trivial upper bound on the maximum length of a compound "walk" built up of variable-length jumps, and a considerably less trivial lower bound on its m…
