A Fast Way to Compute Functional Determinants of Radially Symmetric Partial Differential Operators in General Dimensions
Jin Hur, Hyunsoo Min
Recently the partial wave cutoff method was developed as a new calculational scheme for a functional determinant of quantum field theory in radial backgrounds. For the contribution…
Renormalized Effective Actions in Radially Symmetric Backgrounds: Exact Calculations Versus Approximation Methods
Gerald V. Dunne, Jin Hur, Choonkyu Lee +1
Our previously-developed calculational method (the partial wave cutoff method) is employed to evaluate explicitly scalar one-loop effective actions in a class of radially symmetric…
Instanton Determinant with Arbitrary Quark Mass: WKB Phase-shift Method and Derivative Expansion
Gerald V. Dunne, Jin Hur, Choonkyu Lee +1
The fermion determinant in an instanton background for a quark field of arbitrary mass is studied using the Schwinger proper-time representation with WKB scattering phase shifts fo…
On mass dependences of the one-loop effective action in simple backgrounds
O-Kab Kwon, Choonkyu Lee, Hyunsoo Min
If background fields are soft on the scale set by mass of the particle involved, a reliable approximation to the field-theoretic one-loop effective action is obtained by a systemat…
