Existence of two distinct valence bond solid states in the dimerized frustrated ferromagnetic -- chain
Jędrzej Wardyn, Satoshi Nishimoto, Cliò Efthimia Agrapidis
We study the frustrated and dimerized ferromagnetic-antiferromagnetic -- chain using the density-matrix renormalization group (DMRG) method. Based on numerical calc…
Phase diagram of the Kitaev-Heisenberg model using various finite-size clusters
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We estimate phase boundaries of four ordered and two spin-liquid phases for the spin- Kitaev-Heisenberg (KH) model using four kinds of relatively-small clusters, based…
Study of Staggered Magnetization in the Spin- Square-Lattice Heisenberg Model Using Spiral Boundary Conditions
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We propose an efficient numerical method to obtain local order parameter in two-dimensional systems using spiral boundary conditions. As a benchmark, we first estimate the magnitud…
NaRuO: Kitaev-Heisenberg exchange in triangular-lattice setting
Pritam Bhattacharyya, Nikolay A. Bogdanov, Satoshi Nishimoto +2
Kitaev exchange, a new paradigm in quantum magnetism research, occurs for 90 metal-ligand-metal links, transition ions, and sizable spin-orbit coupling. It is…
Disorder effects in the Kitaev-Heisenberg model
Ayushi Singhania, Jeroen van den Brink, Satoshi Nishimoto
We study the interplay of disorder and Heisenberg interactions in Kitaev model on honeycomb lattice. The effect of disorder on the transition between Kitaev spin liquid and magneti…
Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe
Tao Xie, A. A. Eberharter, Jie Xing +14
Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly en…
