Aharonov-Bohm-Coulomb Problem in Graphene Ring
Eylee Jung, Mi-Ra Hwang, ChangSoo Park +1
We study the Aharonov-Bohm-Coulomb problem in a graphene ring. We investigate, in particular, the effects of a Coulomb type potential of the form on the energy spectrum of Di…

Resonant tunnelling and quenching of tunnel splitting in Wess-Zumino nanospin systems
Soo-Young Lee, Sahng-Kyoon Yoo
We investigate the energy spectrum of the biaxial spin systems with magnetic field along the hard anisotropy axis by using the complex periodic orbit theory. All important features…

Oscillation of the tunnel splitting in nanospin systems within the particle mapping formalism
Sahng-Kyoon Yoo, Soo-Young Lee, Dal-Ho Yoon +1
The oscillation of tunnel splitting in the biaxial spin system within magnetic field along the anisotropy axis is analyzed within the particle mapping approach, rather than in the…
