The magnetic nature of the altermagnet candidate RuO remains under debate. It has been recently shown from quantum oscillations and angle-resolved photoemission spectroscopy (A…
Direct evidence for the absence of coupling between shear strain and superconductivity in Sr2RuO4
Giordano Mattoni, Thomas Johnson, Atsutoshi Ikeda +4
The superconducting symmetry of Sr2RuO4 has been intensely debated for many years. A crucial controversy recently emerged between shear-mode ultrasound experiments, which suggest a…
Magneto-cubic and magneto-linear dependence observed in an in-plane anomalous Hall magnet
Ayano Nakamura, Shinichi Nishihaya, Mitsuru Akaki +9
The Hall effect, particularly that arising from in-plane magnetic field, has recently emerged as a sensitive probe of quantum geometric properties in solids. Especially in trigonal…
Growth of ultra-clean single crystals of RuO2
Shubhankar Paul, Giordano Mattoni, Hisakazu Matsuki +4
We report the details of the growth of ultra-clean single crystals for RuO2, a candidate material for altermagnetism. By using a crystal-growth tube with a necking structure and pr…

Recent observation of the in-plane anomalous Hall effect in magnetic Weyl semimetal EuCd2Sb2 has drawn attention to out-of-plane orbital magnetization induced by an in-plane field…
Anomalous Hall effect in Dirac semimetal probed by in-plane magnetic field
Shinichi Nishihaya, Hiroaki Ishizuka, Yuki Deguchi +5
Intrinsic anomalous Hall effect (AHE) formulated by geometric properties of Bloch wavefunctions is a ubiquitous transport phenomenon not limited to magnetic systems but also allowe…
Spin-degenerate bulk bands and topological surface states associated with Dirac nodal lines in RuO2
T. Osumi, K. Yamauchi, S. Souma +13
Altermagnets are a novel platform to realize exotic electromagnetic properties distinct from those of conventional ferromagnets and antiferromagnets. We report results of micro-foc…
Hydride superconductivity: here to stay
Gregory S. Boebinger, Andrey V. Chubukov, Ian R. Fisher +12
The field of hydride superconductivity has recently been mired in a controversy that might divert attention from the question of central importance: do hydrides support genuine sup…
Hyperuniform properties of the square-triangle tilings
Akihisa Koga, Shiro Sakai, Yushu Matsushita +1
We study hyperuniform properties for the square-triangle tilings. The tiling is generated by a local growth rule, where squares or triangles are iteratively attached to its boundar…
