Phase Transitions for Cuboc Orders in Stacked Kagome Heisenberg Systems
Kouichi Seki, Kouichi Okunishi
Using the event-chain Monte Carlo (MC) algorithm, we investigate phase transitions of the stacked Kagome Heisenberg systems with classical vector spins including up to the 3rd-near…

Snapshot spectra in the world-line quantum Monte Carlo for one-dimensional quantum spin systems
Kouichi Seki, Kouichi Okunishi
We introduce a snapshot density matrix and snapshot spectrum for world-line (WL) quantum Monte Carlo simulations, by integrating out the continuous-imaginary-time index of WL snaps…

Spin-wave analysis for Kagome-triangular spin system and coupled spin tubes: low-energy excitation for the cuboc order
Masahiro Ochiai, Kouichi Seki, Kouichi Okunishi
The coupled spin tube system, which is equivalent to a stacked Kagome-triangular spin system, exhibits the cuboc order -- a non-coplanar spin order with a twelve-sublattice structu…
