Discovery of Nodal-Line Superconductivity in Chiral Crystals
Chiral crystals, whose key feature is the structural handedness, host exotic quantum phenomena driven by the interplay of band topology, spin-orbit coupling (SOC), and electronic correlations. Due to the limited availability of suitable chiral-crystal materials, their unconventional superconductivity (SC) remains largely unexplored.
Here, the discovery ...
A New Quantum Landscape: Coexisting High-Tc Superconductivity, Magnetism, and Complex Charge Order in LaRu3Si2.
Despite intense research on kagome superconductors, many fundamental questions remain—especially regarding the unconventional nature of their charge order and superconducting phases. These materials are rich in complexity, and to truly unravel their behavior, a broad and integrated approach is essential. In our study ...
Pressure effect on the spin density wave transition in La2PrNi2O6.96
High-pressure studies reveal a stark contrast between the superconducting properties of double-layer Ruddlesden-Popper (RP) nickelates La2PrNi2O7 and La3Ni2O7. While La2PrNi2O7 exhibits bulk superconductivity, La3Ni2O7 displays filamentary behavior, suggesting that superconductivity is confined to phase interfaces rather than the bulk. Since magnetism emerges ...
Fun Facts about Magnetism
The video is from the Visitor Centre psi forum of the Paul Scherrer Institute, where a cartoon avatar of Rhea Stewart, who was a Postdoc in Mesoscopic Systems, explains about our research to science enthusiasts.
Upcoming Seminars
Information to visitors: The seminars of the group are open to members of PSI and Project Partners, while the group meeting following the seminar is for group members only.
