Chiral zero modes in superconducting nanowires with Dresselhaus spin-orbit coupling
Hsien-chung Kao
Using chiral decomposition, we are able to find analytically the zero modes and the conditions for such modes to exist in the Kitaev ladder model and superconducting nanowires with…
Binding Transition in Quantum Hall Edge States
Hsien-chung Kao, Chia-Hung Chang, Xiao-Gang Wen
We study a class of Abelian quantum Hall (QH) states which are topologically unstable (T-unstable). We find that the T-unstable QH states can have a phase transition on the edge wh…
The Non-abelian Chern-Simons Coefficient in the Higgs Phase
Hsien-chung Kao
We calculate the one loop corrections to the Chern-Simons coefficient in the Higgs phase of Yang-Mills Chern-Simons Higgs theories. When the gauge group is SU(N), we show, by t…
Exact Solution of Frenkel-Kontorova Models with a Complete Devil's Staircase in Higher Dimensions
Hsien-chung Kao, Shih-Chang Lee, Wen-Jer Tzeng
We solve exactly a class of Frenkel-Kontorova models with piecewise parabolic potential, which has sub-wells in a period. With careful analysis, we show that the phase diagram…
Self-DUal SU(3) Chern-Simons Higgs Systems
Hsien-Chung Kao, Kimyeong Lee
We explore self-dual Chern-Simons Higgs systems with the local and global symmetries where the matter field lies in the adjoint representation. We show that there ar…
