High-field fate of the Kitaev quantum spin liquid in -RuCl
K. Imamura, R. Ohno, Y. C. Tsuzuki +15
Kitaev quantum spin liquids (KQSLs) host fractionalized excitations described by itinerant Majorana quasiparticles and gapped fluxes (visons), providing a platform for emerge…
Magnetoelastic mapping of the high-field phase diagram in the topological cubic helimagnet SrFeO
Masaki Gen, Shun Okumura, Shusaku Imajo +9
The cubic perovskite SrFeO is a prototypical centrosymmetric itinerant magnet that hosts a quadruple- hedgehog-antihedgehog lattice and exhibits a complex magnet…
Search for magnetoacoustic quantum oscillations in the insulating phase of YbB
Ryosuke Kurihara, Atsuhiko Miyata, Koji Araki +9
A highly exotic phenomenon in solid-state physics is the observation of magnetic quantum oscillations in insulators. For instance, in the Kondo insulator YbB various groups…
Unified Description of Spin-Lattice Coupling and Thermodynamics in the Pyrochlore Heisenberg Antiferromagnet
Masaki Gen, Hidemaro Suwa, Shusaku Imajo +6
We study an extended model to describe the spin-lattice coupling, incorporating individual vibrations of bonds and atomic sites alongside distance-dependent exchange interactions.…
Fate of Pomeranchuk effect in ultrahigh magnetic fields
Naofumi Matsuyama, So Yokomori, Toshihiro Nomura +8
The Pomeranchuk effect is a counterintuitive phenomenon where liquid helium-3 (3He) solidifies under specific pressures, not when cooled, but when heated. This behaviour originates…
Systematic evolution of superconducting pairing strength and Seebeck coefficients in correlated infinite-layer LaSrNiO
Motoki Osada, Shusaku Imajo, Yuji Seki +6
The recently discovered superconducting infinite-layer nickelates offer a novel platform to explore an exotic pairing mechanism in multi-band systems towards high-temperature super…
