Majorana representation for topological edge states of massless Dirac fermion with non-quantized Berry phase
F. R. Pratama, Takeshi Nakanishi
We study the bulk-boundary correspondences for zigzag ribbons (ZRs) of massless Dirac fermion in two-dimensional - lattice. By tuning the hopping parameter , t…
Topological edge states of massless fermion with non-quantized and zero Berry phases
F. R. Pratama, Takeshi Nakanishi
We investigate the bulk-boundary correspondence for massless Dirac fermion in - lattice where the Berry phase can be continuously tuned from (graphene) to (…
Magneto-Seebeck coefficient of Fermi-liquid in three-dimensional Dirac/Weyl semimetal
F. R. Pratama, Riichiro Saito, Nguyen T. Hung
We investigate dissipationless magneto-Seebeck effect in three-dimensional Dirac/Weyl semimetal. The Hall resistivity and thermoelectric Hall coefficient exhibit…
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…
