Boundary Resonances in S = 1/2 Antiferromagnetic Chains under a Staggered Field
Shunsuke C. Furuya, Masaki Oshikawa
We develop a boundary field theory approach to electron spin resonance in open Heisenberg antiferromagnetic chains with an effective staggered field. In terms of the sine G…
Single-ion anisotropy in Haldane chains and form factor of the O(3) nonlinear sigma model
Shunsuke C. Furuya, Takafumi Suzuki, Shintaro Takayoshi +2
We consider spin-1 Haldane chains with single-ion anisotropy, which exists in known Haldane chain materials. We develop a perturbation theory in terms of anisotropy, where magnon-m…
Electron spin resonance shift in spin ladder compounds
Shunsuke C. Furuya, Pierre Bouillot, Corinna Kollath +2
We analyze the effects of different coupling anisotropies in spin-1/2 ladder on the Electron Spin Resonance (ESR) shift. Combining a perturbative expression in the anisotropies wit…
A semi-classical approach to electron spin resonance in quantum spin systems
Shunsuke C. Furuya, Masaki Oshikawa, Ian Affleck
We develop a semi-classical approximation to electron spin resonance in quantum spin systems, based on the rotor or non-linear sigma model. The classical time evolution is studied…
