Andrej Vilfan from the Department of Condensed Matter Physics F5 and colleagues from Germany and Great Britain have published an article in the journal Physical Review Letters with the title Lorentz Reciprocal Theorem in Fluids with Odd Viscosity. Fluids with odd viscosity break the time reversal symmetry and consequently the Lorentz reciprocal theorem does not hold. Here we report a way of restoring its validity and demostrate how it can be applied to predict the motion of active particles in such a fluid.

Matej Pregelj from the Department of Condensed Matter Physics F-5, in collaboration with colleagues from the Department of Thin Films and Surfaces and other researchers from Slovenia and Serbia, published the article Perpendicular magnetic anisotropy at room-temperature in sputtered a-Si/Ni/a-Si layered structure with thick Ni (nickel) layers. In the article, they presented a detailed study of nanometer Si/Ni/Si layers, where perpendicular magnetic anisotropy was observed. It is one of the first observations of this property in Si/Ni/Si layers and thus opens up possibilities for the use of such layers in memory units, sensors, logic chips, etc.
