Superconductivity and a van Hove singularity con ned to the surface of a topological semimetal

The interplay between topology and superconductivity generated great interest in condensed matter physics. Here, we unveil an unconventional two-dimensional superconducting state in the Dirac nodal line semimetal ZrAs2 which is exclusively con ned to the top and bottom surfaces within the crystal’s ab plane. 

As a remarkable consequence ...

Momentum-resolved fingerprint of Mottness in layer-dimerized Nb3Br8

Crystalline solids can become band insulators due to fully lled bands, or Mott insulators due to strong electronic correlations. While Mott insulators can theoretically occur in systems with an even number of electrons per unit cell, distinguishing them from band insulators experimentally has remained a longstanding challenge. 

In this work, we present ...

Vacancy-induced suppression of charge density wave order and its impact on magnetic order in kagome antiferromagnet FeGe

Two-dimensional (2D) kagome lattice metals are interesting because their corner sharing triangle structure enables a wide array of electronic and magnetic phenomena. Recently, post-growth annealing is shown to both suppress charge density wave (CDW) order and establish long-range CDW with the ability to cycle between states repeatedly in the kagome antiferromagnet FeGe. 

Here we perform ...

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.
