Conductance and Its Variance of Disordered Wires with Symplectic Symmetry in the Metallic Regime
Hiroshi Sakai, Yositake Takane
The conductance of disordered wires with symplectic symmetry is studied by a random-matrix approach. It has been shown that the behavior of the conductance in the long-wire limit c…
DC Josephson Effect in a Tomonaga-Luttinger Liquid
Yositake Takane
The dc Josephson effect in a one-dimensional Tomonaga-Luttinger (TL) liquid is studied on the basis of two bosonized models. We first consider a TL liquid sandwiched between two su…
DMPK Equation for Transmission Eigenvalues in Metallic Carbon Nanotubes
Yositake Takane
The Dorokhov-Mello-Pereyra-Kumar (DMPK) equation for transmission eigenvalues is derived for metallic carbon nanotubes with several conducting channels when the potential range of…
Conductance of Disordered Wires with Symplectic Symmetry: Comparison between Odd- and Even-Channel Cases
Yositake Takane
The conductance of disordered wires with symplectic symmetry is studied by numerical simulations on the basis of a tight-binding model on a square lattice consisting of M lattice s…
Quantum Electron Transport in Disordered Wires with Symplectic Symmetry
Yositake Takane
The conductance of disordered wires with symplectic symmetry is studied by the supersymmetric field theory. Special attention is focused on the case where the number of conducting…
Pulse Control of Decoherence in a Qubit Coupled with a Quantum Environment
Takahiro Murakami, Yositake Takane
We study the time evolution of a qubit linearly coupled with a quantum environment under a sequence of short pi pulses. Our attention is focused on the case where qubit-environment…
