Static and Dynamical Properties of the Spin-1/2 Equilateral Triangular-Lattice Antiferromagnet BaCoSbO
J. Ma, Y. Kamiya, Tao Hong +7
We present single-crystal neutron scattering measurements of the spin-1/2 equilateral triangular lattice antiferromagnet BaCoSbO. Besides confirming that the Co…
Topological defects as relics of emergent continuous symmetry and Higgs condensation of disorder in ferroelectrics
Shi-Zeng Lin, Xueyun Wang, Yoshitomo Kamiya +9
Lars Onsager and Richard Feynman envisioned that the three-dimensional (3D) superfluid-to-normal transition in He occurs through the proliferation of vortices. This proce…
Magnetic three states of matter: A quantum Monte Carlo study of spin liquids
Yoshitomo Kamiya, Yasuyuki Kato, Joji Nasu +1
We present thermodynamic phase diagrams showing magnetic analog of "three states of matter," namely, spin liquid, paramagnetic, and magnetically ordered phases, obtained by unbiase…
Three-Dimensional Crystallization of Vortex Strings in Frustrated Quantum Magnets
Zhentao Wang, Yoshitomo Kamiya, Andriy H. Nevidomskyy +1
We demonstrate that frustrated exchange interactions can produce exotic 3D crystals of vortex strings near the saturation field (H=Hsat) of body- and face-centered cubic Mott insul…
