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…
