Laboratory Condensed Matter (LSC)
in the Photon Science Division
The research focusses on condensed matter and materials science using synchrotron radiation. For this we use the whole range of spectroscopy, imaging and diffraction techniques.
Current Highlights and News
New material also reveals new quasiparticles
Researchers at PSI have investigated a novel crystalline material at the Swiss Light Source SLS that exhibits electronic properties never seen before. Among other things, they were able to detect a new type of quasiparticle: so-called Rarita-Schwinger fermions.
An iodine polymeric chain with tunable conductivity
The progressive hydrostatic compression of I2 and I3- units in an organic salt lead to a homoatomic polymeric chain. As the I---I distance collapses the covalent character of the interaction becomes more relevant, leading to a pressure-tunable increased conductivity.
