Complete Entanglement Structure of the Kitaev Honeycomb Spin Liquid from Exact Tensor Networks
Hidehiro Saito, Chisa Hotta
While most of the features of the Kitaev honeycomb model are already clarified from the combined plaquette and Majorana fermion picture, we show that retrieving the…
Incommensurate quantum magnet based on 4f-electron in a zigzag spin-1/2 chain of YbCuS
T. Onimaru, Y. Ohmagari, S. Mizutani +8
We performed high-resolution powder neutron diffraction experiments and discovered an elliptic helical incommensurate magnetic structure in the semiconducting rare-earth magnet YbC…
Cluster-projected matrix product state: framework for engineering exact quantum many-body ground states in one and two dimensions
Hidehiro Saito, Chisa Hotta
We propose a framework to design concurrently a frustration-free quantum many-body Hamiltonian and its numerically exact ground states on a sufficiently large finite-size cluster i…
Phase diagram of the quantum spin-1/2 Heisenberg- model on a frustrated zigzag chain
Hidehiro Saito, Chisa Hotta
We investigate the quantum spin-1/2 zigzag chain with frustrated - Heisenberg interactions, incorporating additional off-diagonal exchange interactions known as the t…
Exact matrix product states at the quantum Lifshitz tricritical point in a spin-1/2 zigzag-chain antiferromagnet with anisotropic -term
Hidehiro Saito, Chisa Hotta
Quantum anisotropic exchange interactions in magnets can induce competitions between phases in a different manner from those typically driven by geometrically frustrated interactio…
Deriving quantum spin model for a zigzag-chain ytterbium magnet with anisotropic exchange interactions
Hidehiro Saito, Hiroki Nakai, Chisa Hotta
We derive a quantum spin Hamiltonian of the spin-1/2 zigzag chain realized in a rare earth ytterbium-based magnetic insulator, YbCuS2. This material undergoes a transition at 0.95K…
