Stiffness from Disorder in Triangular-Lattice Ising Thin Films

Shi-Zeng Lin, Yoshitomo Kamiya, Gia-Wei Chern +1

We study the triangular lattice Ising model with a finite number of vertically stacked layers and demonstrate a low temperature reentrance of two Berezinskii-Kosterlitz-Thouless tr…

Quantum phase diagram of the triangular-lattice antiferromagnet BaCoSbO

G. Koutroulakis, T. Zhou, C. D. Batista +4

The magnetic phases of the ideal spin-1/2 triangular-lattice antiferromagnet BaCoSbO are identified and studied using Ba nuclear magnetic resonance (NMR) sp…

Phase diagram and the strong-coupling fixed point in the disordered O(n) loop model

Hirohiko Shimada, Jesper Lykke Jacobsen, Yoshitomo Kamiya

We numerically study the phase diagram and critical properties of the two-dimensional disordered O(n) loop model by using the transfer matrix and the worm Monte Carlo methods. The…

Multiferroicity with coexisting isotropic and anisotropic spins in CaCoMnO

Jae Wook Kim, Y. Kamiya, E. D. Mun +9

We study magnetic and multiferroic behavior in CaCoMnO (0.97) by high-field measurements of magnetization (), magnetostriction (()/), elec…

Magnetic vortex crystals in frustrated Mott insulator

Yoshitomo Kamiya, Cristian D. Batista

Quantum fluctuations become particularly relevant in highly frustrated quantum magnets and can lead to new states of matter. We provide a simple and robust scenario for inducing ma…
