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…
Refined Sensitivity Estimates for Single-Molecule Magnet Dark Matter Detectors
Andrew Eberhardt, Tomoya Fukui, Ryosuke Takehara +8
We revisit the sensitivity of Single Molecule Magnet (SMM) crystals as detectors for low-mass dark matter. In previous work, we established the concept of the ``magnetic bubble cha…
Revealing nonvolatile behaviors in magneto-thermal switching using microstructure-controlled superconducting composites
Keigo Ito, Yui Sakamoto, Hossein Sepehri-Amin +12
Thermal conductivity in a conductor changes by the application of an external magnetic field, which functions as a magneto-thermal switch. For superconductors, a large magneto-ther…
Energy-Resolved Real-Space Imaging of Orbital Nematicity in an Fe-Based Superconductor
Asato Onishi, Zifan Xu, Cédric Bareille +7
Electronic nematicity in Fe-based superconductors is manifested by spontaneous rotational symmetry breaking and the formation of nematic domains with mutually orthogonal directions…
Bulk excitations in ultraclean -RuCl: Quantitative evidence for Majorana dispersions in a Kitaev quantum spin liquid
Kumpei Imamura, Ryuichi Namba, Riku Ishioka +6
The spin-orbit coupled Mott insulator -RuCl has emerged as a prime candidate for realizing the Kitaev quantum spin liquid (KQSL), characterized by Majorana quasiparticles,…
Anomalous Electrical Transport in the Kagome Magnet YbFeGe
Weiliang Yao, Supeng Liu, Hodaka Kikuchi +19
Two-dimensional (2D) kagome metals offer a unique platform for exploring electron correlation phenomena derived from quantum many-body effects. Here, we report a combined study of…
