SUMMARY:Condensed matter seminar: Two-phase superconductivity in a locally 
 non-centrosymmetric system
CLASS:PUBLIC
DESCRIPTION:Elena HassingerMPI for Chemical Physics of Solids and&nbsp\;TU 
 MunichI will report on the discovery of unconventional superconductivity i
 n CeRh2As2. Although it appears at temperatures below 1 K\, the supercondu
 cting state is extremely robust under the application of magnetic fields a
 nd presents a unique phase diagram. Most interestingly\, a field-induced p
 hase transition within the superconducting state appears for c-axis fields
  in magnetisation\, susceptibility and magnetostriction indicating two sep
 arate superconducting states. The phase diagram can be understood by takin
 g into account the staggered spin-orbit coupling at the Ce position. In th
 at picture\, the magnetic field drives a transition from even to odd parit
 y superconductivity. The angle dependence of the critical fields strongly 
 reinforces this interpretation.\n\nMore information at: https://www.physas
