Edge states and topological phases in non-Hermitian systems
Kenta Esaki, Masatoshi Sato, Kazuki Hasebe +1
Topological stability of the edge states is investigated for non-Hermitian systems. We examine two classes of non-Hermitian Hamiltonians supporting real bulk eigenenergies in weak…
Unification of Laughlin and Moore-Read States in SUSY Quantum Hall Effect
Kazuki Hasebe
Based on the recently proposed SUSY quantum Hall effect, we show that Laughlin and Moore-Read states are related by a hidden SUSY transformation. Regarding the SUSY Laughlin wavefu…
SU(4) Coherent Effects to the Canted Antiferromagnetic Phase in Bilayer Quantum Hall Systems at =2
K. Hasebe
In bilayer quantum Hall (BLQH) systems at =2, three different kinds of ground states are expected to be realized, i.e. a spin polarized phase (spin phase), a pseudospin polarize…
Grassmannian Fields and Doubly Enhanced Skyrmions in Bilayer Quantum Hall system at
K. Hasebe, Z. F. Ezawa
At the filling factor the bilayer quantum Hall system has three phases, the ferromagnetic phase (spin phase), the spin singlet phase (ppin phase) and the canted antiferromagn…
Interlayer Exchange Interactions, SU(4) Soft Waves and Skyrmions in Bilayer Quantum Hall Ferromagnets
Z. F. Ezawa, K. Hasebe
The Coulomb exchange interaction is the driving force for quantum coherence in quantum Hall systems. We construct a microscopic Landau-site Hamiltonian for the exchange interaction…
