Thermal transport of the frustrated spin-chain mineral linarite: Magnetic heat transport and strong spin-phonon scattering
Matthias Gillig, Xiaochen Hong, Piyush Sakrikar +6
The mineral linarite (PbCuSO(OH)) forms a monoclinic structure where a sequence of Cu(OH) units forms a spin- chain. Competing ferromagnetic nearest-neighb…
Spin- impurities with XXZ anisotropy in a spin-1/2 Heisenberg chain
Ayushi Singhania, Masahiro Kadosawa, Yukinori Ohta +2
We study the effect of anisotropy of spin- impurities on an antiferromagnetic SU(2) Heisenberg chain. The magnetic impurities are assumed to have an XXZ-type anisotropic exchang…
Characterization of topological insulators based on the electronic polarization with spiral boundary conditions
Masaaki Nakamura, Shohei Masuda, Satoshi Nishimoto
We introduce the electronic polarization originally defined in one-dimensional lattice systems to characterize two-dimensional topological insulators. The main idea is to use spira…
Anomalous and Anisotropic Nonlinear Susceptibility in the Proximate Kitaev Magnet -RuCl
Ludwig Holleis, Joseph Prestigiacomo, Zhijie Fan +5
The leading order nonlinear (NL) susceptibility, , in a paramagnet is negative and diverges as . This divergence is destroyed when spins correlate and the NL…
Anomalous fractional quantization in the kagomelike Heisenberg ladder: Emergence of the effective spin-1 chain
Tomoki Yamaguchi, Yukinori Ohta, Satoshi Nishimoto
We study a Kagome-like spin- Heisenberg ladder with competing ferromagnetic (FM) and antiferromagnetic (AFM) exchange interactions. Using the density-matrix renormalization gr…
Exact Plaquette-Ordered Ground States with Exact Edge States of the Generalized Hubbard Model in Corner Sharing Lattices
Naoto Nakatsuji, Satoshi Nishimoto, Masaaki Nakamura
We discuss exact plaquette-ordered ground states of the generalized Hubbard model based on the projection operator method for several corner sharing lattices: Kagome, checkerboard,…
