Oxygen-isotope effect on the density wave transitions in La3Ni2O7
The isotope effect is a powerful probe of electron-phonon interactions in solid-state systems, offering key insights into how atomic mass influences emergent quantum states. Here, the impact of oxygen-isotope substitution (16O→18O) on charge- and spin-density wave (CDW and SDW) transitions in the double-layer Ruddlesden-Popper nickelate La3Ni2O7 is investigated ...
Pressure and oxygen-isotope substitution on density-wave transitions in La4Ni3O10
Understanding the interplay between magnetism and superconductivity in nickelate systems is a key objective in condensed matter physics. Gaining microscopic insights into magnetism—particularly as it emerges near superconductivity—requires a synergistic approach that combines complementary experimental techniques with controlled tuning of external parameters. In this paper, we present ...
Niobium’s intrinsic coherence length and penetration depth revisited using low-energy muon spin spectroscopy and secondary-ion mass spectrometry
We report direct, simultaneous measurements of the London penetration depth (λL ) and Bardeen-Cooper-Schrieffer coherence length (ξ0) in oxygen-doped niobium, with impurity concentrations spanning the “clean”to “dirty” limits ...

Japanese – Swiss BRIDGE Workshop at PSI
BRIDGE stands for Bridging Research Innovations in Diverse muon and neutron science by GEneral collaboration between Japan and Switzerland. After a first remote edition of this new workshop series in 2022, an in-person BRIDGE workshop took place at PSI, October 18-20, 2023.

Developments of the MIXE technique at PSI
With muons, PSI researchers can examine objects non-destructively. This helps in archaeology and battery development.
