Edge states of Spin-1/2 Two-Leg Ladder with Four-Spin Ring Exchange
Mitsuhiro Arikawa, Shou Tanaya, Isao Maruyama +1
A topological insulator and its spin analogue as a gapped spin liquid have characteristic low energy excitations (edge states) within the gap when the systems have boundaries. This…
Dynamics in two-leg spin ladder with a four-spin cyclic interaction
S. Nishimoto, M. Arikawa
We study two-leg Heisenberg ladder with four-spin cyclic interaction using the (dynamical) density-matrix renormalization group method. We demonstrate the dependence of the low-lyi…
Basic properties of three-leg Heisenberg tube
S. Nishimoto, M. Arikawa
We study three-leg antiferromagnetic Heisenberg model with the periodic boundary conditions in the rung direction. Since the rungs form regular triangles, spin frustration is induc…
Low-lying excitations of the three-leg spin tube using the density-matrix renormalization group method
S. Nishimoto, M. Arikawa
Using the (dynamical) density-matrix renormalization group method, we study the low-energy physics of three-leg antiferromagnetic Heisenberg model where the periodic boundary condi…
Exact density matrix of the Gutzwiller wave function: II. Minority spin component
Onuttom Narayan, Yoshio Kuramoto, Mitsuhiro Arikawa
The density matrix, i.e. the Fourier transform of the momentum distribution, is obtained analytically for all magnetization of the Gutzwiller wave function in one dimension with ex…
Exact spin dynamics of the 1/r^2 supersymmetric t-J model in a magnetic field
Mitsuhiro Arikawa, Yasuhiro Saiga
The dynamical spin structure factor S^{zz}(Q,omega) in the small momentum region is derived analytically for the one-dimensional supersymmetric t-J model with 1/r^2 interaction. St…
