Two scenarios for superconductivity in CeRh2As2

CeRh2As2, a nonsymmorphic heavy fermion material, was recently reported to host a remarkable temperature versus z-axis magnetic-field phase diagram with two superconducting phases. In this material, the two inequivalent Ce sites per unit cell, related by inversion symmetry, introduce a sublattice structure corresponding to an extra internal degree of freedom. In this work, we propose a classification of the possible superconducting states in CeRh2As2 from the two Ce-sites' perspective.

New blueprint for more stable quantum computers

Matter and Material Quantum Research

PSI researchers have shown how faster and better defined quantum bits can be created. The central elements are magnetic atoms from the class of so-called rare-earth metals, selectively implanted into the crystal lattice of a material.

Weissbuch Radiochemie Schweiz

In December 2020, the Swiss Academy of Sciences (SCNAT) published its white book on radiochemical education in Switzerland. The report was authored under the lead of Prof. Dr. Roger Alberto (University of Zurich), Dr. Mario Burgener (Spiez Laboratory), and Prof. em. Dr. Heinz W. Gäggeler (University of Bern/Paul Scherrer Institute) and comprises contributions from many experts on the topic from various institutions throughout Switzerland. The white book highlights the imminent loss of experts in the field of radiochemistry and provides solutions to counteract this development.

Radiochemistry at ETH Zurich

As of December 10, 2020, the ETH Zurich appointed PSI’s Prof. Dr. Patrick Steinegger as assistant professor of radiochemistry  (tenure track). Thus, the ETH domain took first counter  measures against the imminent loss of radiochemical expertise  in Switzerland, emphasized in the “Weissbuch Radiochemie  Schweiz” by the Swiss Academy of Sciences (SCNAT).  Furthermore, the December issue of CHIMIA (Swiss Chemical  Society) invited to present the diverse radiochemical activities  throughout the country.
