Supersymmetry Breaking in a Generalized Nicolai Model with Fermion Pairing
Urei Miura, Keisuke Totsuka
We introduce a supersymmetric lattice fermion model that contains both fermion pairing and the interacting Nicolai model. This model possesses a single control parameter, , intr…
Ferromagnetism in the SU(N) Kondo lattice model -- SU(N) double exchange and supersymmetry
Keisuke Totsuka
We study the ground-state properties of the SU(N)-generalization of the Kondo-lattice model in one dimension when the Kondo coupling J_K (both ferromagnetic and antiferromagnetic)…
Electric and Magnetic Properties of Higher-Spin Kondo-Heisenberg Models at Strong Coupling
Riku Masui, Keisuke Totsuka
We study higher-spin () generalization of the one-dimensional Kondo-Heisenberg model, in which the local spin- moments of the Kondo lattice model interact with each ot…
Intrinsic suppression of topological thermal Hall effect in an exactly solvable quantum magnet
S. Suetsugu, T. Yokoi, K. Totsuka +7
In contrast to electron (fermion) systems, topological phases of charge neutral bosons have been poorly understood despite recent extensive research on insulating magnets. The most…
Abelian SU Chiral Spin Liquids on the Square Lattice
Ji-Yao Chen, Jheng-Wei Li, Pierre Nataf +7
In the physics of the Fractional Quantum Hall (FQH) effect, a zoo of Abelian topological phases can be obtained by varying the magnetic field. Aiming to reach the same phenomenolog…
Non-Abelian Aharonov-Casher Phase Factor in Mesoscopic Systems
Yshai Avishai, Keisuke Totsuka, Naoto Nagaosa
The matrix-valued Aharonov-Casher phase factor (related to the c-number Aharonov-Casher phase ) plays an important role in the physics of mesoscopic…
