Quantum Spin Chains with Nonlocally-Correlated Random Exchange Coupling and Random-Mass Dirac Fermions
K. Takeda, I. Ichinose
S=1/2 quantum spin chains and ladders with random exchange coupling are studied by using an effective low-energy field theory and transfer matrix methods. Effects of the nonlocal c…
Effects of Long-Range Correlations in Random-Mass Dirac Fermions
K. Takeda, I. Ichinose
In the previous paper, we studied the random-mass Dirac fermion in one dimension by using the transfer-matrix methods. We furthermore employed the imaginary vector potential method…
Random-Mass Dirac Fermions in an Imaginary Vector Potential (II): Long-Range Correlated Random Mass
K. Takeda, I. Ichinose
In the previous paper, we studied the random-mass Dirac fermion in one dimension by using the transfer-matrix methods and by introducing an imaginary vector potential in order to c…
Random-Mass Dirac Fermions in an Imaginary Vector Potential (I): Delocalization Transition and Localization Length
K. Takeda, I. Ichinose
In this and subsequent papers, one dimensional system of Dirac fermions with a random-varying mass is studied by the transfer-matrix methods which we developed recently. We investi…
Pions in Lattice QCD with the Overlap Fermions at Strong Gauge Coupling
Ikuo Ichinose, Keiichi Nagao
In the previous paper we developed a strong-coupling expansion for the lattice QCD with the overlap fermions and showed that Lüsher's "extended" chiral symmetry is spontaneously br…
