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…
