Correlation functions at the topological quantum phase transition in the S=1 XXZ chain with single-ion anisotropy
Toshiya Hikihara, Akira Furusaki
We study the one-dimensional S=1 XXZ spin model with single-ion anisotropy. It is known that at the transition points between the Haldane and large-D phases, the model exhibits a q…
Decay of fermionic quasiparticles in one-dimensional quantum liquids
K. A. Matveev, A. Furusaki
The low-energy properties of one-dimensional quantum liquids are commonly described in terms of the Tomonaga-Luttinger liquid theory, in which the elementary excitations are free b…
Magnetic phase diagram of the spin-1/2 antiferromagnetic zigzag ladder
T. Hikihara, T. Momoi, A. Furusaki +1
We study the one-dimensional spin-1/2 Heisenberg model with antiferromagnetic nearest-neighbor J_1 and next-nearest-neighbor J_2 exchange couplings in magnetic field h. With varyin…
Numerical renormalization-group study of spin correlations in one-dimensional random spin chains
T. Hikihara, A. Furusaki, M. Sigrist
We calculate the ground-state two-spin correlation functions of spin-1/2 quantum Heisenberg chains with random exchange couplings using the real-space renormalization group scheme.…
Resonant tunneling through a quantum dot weakly coupled to quantum wires or quantum Hall edge states
A. Furusaki
Resonant tunneling through a quantum dot weakly coupled to Tomonaga-Luttinger liquids is discussed. The linear conductance due to sequential tunneling is calculated by solving a ma…
Tunneling through a barrier in Tomonaga-Luttinger liquid connected to reservoirs
Akira Furusaki, Naoto Nagaosa
The transport through a barrier is studied for a Tomonaga-Luttinger liquid of finite length connected to reservoirs. An effective action for the phase variable at the barrier is de…
Theory of strong inelastic co-tunneling
A. Furusaki, K. A. Matveev
We develop a theory of the conductance of a quantum dot connected to two leads by single-mode quantum point contacts. If the contacts are in the regime of perfect transmission, the…
