Justification for zeta function regularization
F. R. Pratama, M. Shoufie Ukhtary, Riichiro Saito
Using the fact that a finite sum of power series are given by the difference between two zeta functions, we justify the usage of the zeta function with a negative variable in physi…
Magnetizations and de Haas-van Alphen oscillations in massive Dirac fermions
F. R. Pratama, M. Shoufie Ukhtary, Riichiro Saito
We theoretically study magnetic field, temperature, and energy band-gap dependences of magnetizations in the Dirac fermions. We use the zeta function regularization to obtain analy…
Intersubband plasmon excitations in doped carbon nanotubes
Daria Satco, Ahmad R. T. Nugraha, M. Shoufie Ukhtary +3
We theoretically investigate intersubband plasmon excitations in doped single wall carbon nanotubes (SWNTs) by examining the dependence of plasmon frequency on the nanotube diamete…
Hidden symmetries in -layer dielectric stacks
Haihao Liu, M. Shoufie Ukhtary, Riichiro Saito
The optical properties of a multilayer system of dielectric media with arbitrary layers is investigated. Each layer is one of two dielectric media, with thickness one-quarter t…
