The international KArlsruhe TRItium Neutrino Experiment (KATRIN) at the Karlsruhe Institute of Technology (KIT) has once again surpassed its own achievements. The latest data establish an upper limit of 0.45 eV/c2 (equivalent to 8 x 10-37 kilograms) for the neutrino mass. With this result, KATRIN, which measures neutrino mass in the laboratory using a model-independent method, has once again set a world record. The researchers have published their results in the journal Science (DOI: 10.1126/science.adq9592).

An international research team coordinated at KIT (Karlsruhe Institute of Technology) has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness and enable them to absorb and release large amounts of elastic energy. The researchers conducted simple compression experiments to confirm the initial theoretical results. Their findings have been published in the science journal Nature.

If qubits lose energy, they can lose coherence and thus their stored information. Determining the key sources of energy loss and adjusting how qubits are made can help researchers design new devices that can retain coherence and thus quantum information for longer amounts of time. In this study, researchers designed a novel way to characterize energy losses in a thin-film resonator. The work found that tantalum construction and annealed sapphire substrates improve device performance.
