Robust topological surface states in skyrmion-host magnets Eu(Ga,Al)4: evidence for dual topology
Yuki Arai, Kosuke Nakayama, Takemi Kato +10
The interplay between real-space topology such as magnetic skyrmions and momentum-space topology characterized by topological surface states (TSSs) is predicted to realize novel ph…
Type-I and Type-II Saddle Points and a Topological Flat Band in a Bi-Pyrochlore Superconductor CsBi2
Yusei Morita, Yongkai Li, Yu-Hao Wei +12
The divergence of the electron density of states (DOS) plays an important role in enhancing many-body interactions and inducing various quantum phases in low-dimensional systems. H…
Pressure-Induced Superconducting-like Transition in the -wave Altermagnet Candidate CsVSeO
Yuanzhe Li, Yilin Han, Liu Yang +29
Altermagnetism generates exchange-type spin splitting without net magnetization and, in its -wave form, resembles the angular symmetry of unconventional -wave superco…
Direct observation of band structure modifications from monolayer WSe2 to Janus WSSe
Masato Sakano, Shunsuke Akatsuka, Takato Yamamoto +19
Janus monolayer transition metal dichalcogenides (TMDs), created by post-growth substitution of the top chalcogen layer, represent a new direction for engineering 2D crystal proper…
Unveiling two-dimensional electron systems on ultra-wide bandgap semiconductor -GaO
Ryu Yukawa, Hiroshi Mizuseki, Suryo Santoso Putro +26
Ultra-wide bandgap (UWBG) semiconductors promise to revolutionize power electronics, yet a fundamental understanding of their interfacial electronic structure has been hindered by…
Development of a linac-based LEPD experimental station for surface structure analysis and coordination with synchrotron radiation ARPES
Rezwan Ahmed, Izumi Mochizuki, Toshio Hyodo +11
We report on the development of a low-energy positron diffraction (LEPD) experimental station for surface structure analysis using a linac-based slow-positron beam. LEPD, the posit…
