Searching for heavy fermion (HF) states in non–f-electron systems becomes an interesting
issue, especially in the presence of magnetism, and can help explain the physics of complex …

Recent progresses using state-of-the-art experimental techniques have motivated a number
of new insights on heavy fermion physics. This article gives a brief summary of the author's …

The normal state out of which unconventional superconductivity in UTe 2 emerges is studied
in detail using a variety of thermodynamic and transport probes. Clear evidence for a broad …

We obtain the conditions necessary for the emergence of various low-temperature ordered
states (local-moment antiferromagnetism, unconventional superconductivity, quantum …

The two-fluid model is a phenomenological description of the gradual change of the itinerant
and local characters of f-electrons with temperature and other tuning parameters and has …

The three-dimensional electronic structure and the nature of Ce 4 f electrons of the Kondo
insulator CeRu4Sn6 are investigated by angle-resolved photoemission spectroscopy …

We report the anomalous breakdown in the scaling of the microscopic magnetic
susceptibility—as measured via the P 31 nuclear magnetic resonance (NMR) shift K—with …

Motivated by the recent discovery of a continuous ferromagnetic quantum phase transition in
CeRh6Ge4 and its distinction from other U-based heavy fermion metals such as UGe2, we …

The local magnetic susceptibility of the spin-triplet superconductor UTe 2 has been
investigated by positive muon (μ+) Knight shift measurements in the normal state. Three …

Resonant x-ray emission spectroscopy (RXES) was employed at the UL III absorption edge
and the L α 1 emission line to explore the 5 f occupancy, nf, and the degree of 5 f-orbital …
