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…

Magnetic phase diagram of the coupled triangular spin tubes for CsCrF4
Kouichi Seki, Kouichi Okunishi
Using Monte Carlo simulations, we explore the magnetic phase diagram of the triangular spin tubes coupled with a ferromagnetic inter-tube interaction for CsCrF4. A planar structure…
