Roles of easy-plane and easy-axis XXZ anisotropy and bond alternation on a frustrated ferromagnetic spin- chain
Hiroshi Ueda, Shigeki Onoda
The spin- Heisenberg chain with a ferromagnetic first-neighbor exchange coupling and an antiferromagnetic second-neighbor has a Haldane dimer ground state with an…
Magnetic Monopole Supercurrent through a Quantum Spin Ice Tunnel Junction
Sho Nakosai, Shigeki Onoda
Magnetic monopoles are hypothetical particles that may exist as quantized sources and sinks of the magnetic field. In materials, they may appear in an emergent quantum electrodynam…
Quantum spin ice under a [111] magnetic field: from pyrochlore to kagomé
Troels Arnfred Bojesen, Shigeki Onoda
Quantum spin ice, modeled for magnetic rare-earth pyrochlores, has attracted great interest for hosting a U(1) quantum spin liquid, which involves spin-ice monopoles as gapped deco…
First-principles design of the spinel iridate Ir2O4 for high-temperature quantum spin ice
Shigeki Onoda, Fumiyuki Ishii
Insulating magnetic rare-earth pyrochlores related to spin ice host emergent bosonic monopolar spinons, which obey a magnetic analogue of quantum electrodynamics and may open a rou…
Quadrupole Order in the Frustrated Pyrochlore TbTiO
H. Takatsu, S. Onoda, S. Kittaka +10
A hidden order that emerges in the frustrated pyrochlore TbTiO with K is studied using specific heat, magnetization, and neutron scatter…
First-principles study on cubic pyrochlore iridates Y2Ir2O7 and Pr2Ir2O7
Fumiyuki Ishii, Yo Pierre Mizuta, Takehiro Kato +3
Fully relativistic first-principles electronic structure calculations based on a noncollinear local spin density approximation (LSDA) are performed for pyrochlore iridates YIr$…
