Stark effect of hydrogenic ions as a test of the indefinite-metric formalism of the eight-component relativistic wave equation for spin- particles
Paulus C. Tjiang, Sylvia H. Sutanto, Vincentius E. W. Tjia
The eight-component relativistic wave equation for spin- particles of Robson and Staudte (FV), a Feshbach--Villars linearization of the Feynman--Gell-Mann…
Destroying Kaluza-Klein and Kerr-Newman black holes
Haryanto M. Siahaan, Paulus C. Tjiang
We investigate the destroying of charged and rotating black holes in Einstein-Maxwell-(dilaton) theory. We show that a test particle with some appropriate properties in the black h…
The Gaussian formula and spherical aberration of the static and moving curved mirrors from Fermat's principle
Sylvia H. Sutanto, Paulus C. Tjiang
The Gaussian formula and spherical aberrations of the static and relativistic curved mirrors are analyzed using the optical path length (OPL) and Fermat's principle. The geometrica…
Efficiency of Carnot Cycle with Arbitrary Gas Equation of State
Paulus C. Tjiang, Sylvia H. Sutanto
The derivation of the efficiency of Carnot cycle is usually done by calculating the heats involved in two isothermal processes and making use of the associated adiabatic relation f…
On the Derivation of Conserved Quantities in Classical Mechanics
Paulus C. Tjiang, Sylvia H. Sutanto
Using a theorem of partial differential equations, we present a general way of deriving the conserved quantities associated with a given classical point mechanical system, denoted…
Test of Gauge Covariance of Fermion-Photon Vertex in Quenched, Massless Three Dimensional Quantum Electrodynamics
Paulus C. Tjiang, Conrad J. Burden
We study the gauge covariance of the fermion-photon vertex in quenched, massless 3-dimensional quantum electrodynamics. A class of vertex Ansätze obtained by generalizing that prop…
