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…
Time-Reversal Symmetry in Non-Hermitian Systems
Masatoshi Sato, Kazuki Hasebe, Kenta Esaki +1
For ordinary hermitian Hamiltonians, the states show the Kramers degeneracy when the system has a half-odd-integer spin and the time reversal operator obeys Θ^2=-1, but no such a d…
Graded Hopf Maps and Fuzzy Superspheres
Kazuki Hasebe
We argue supersymmetric generalizations of fuzzy two- and four-spheres based on the unitary-orthosymplectic algebras, and , respectively. Supersymmetric vers…
Hidden Order and Dynamics in Supersymmetric Valence Bond Solid States -- Super-Matrix Product State Formalism
Kazuki Hasebe, Keisuke Totsuka
Supersymmetric valence bond solid models are extensions of the VBS model, a paradigmatic model of `solvable' gapped quantum antiferromagnets, to the case with doped fermionic holes…
Region of hadron-quark mixed phase in hybrid stars
Tomoki Endo
Hadron--quark mixed phase is expected in a wide region of the inner structure of hybrid stars. However, we show that the hadron--quark mixed phase should be restricted to a narrowe…
