A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center cannot be shrunk to a point. An arbitrary circle inside the bun, however, can. The mathematical ...

KATRIN experiment with new world record for precision measurements

16-Feb-2022

The international KArlsruhe TRItium Neutrino Experiment (KATRIN), located at Karlsruhe Institute of Technology (KIT), has broken an important "barrier" in neutrino physics which is relevant for both particle physics and cosmology. Based on data published in the prestigious journal Nature Physics, ...

Structure may reveal conditions needed for high-temperature superconductivity

04-Feb-2021

When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy. This "magic-angle" transformation in bilayer graphene was observed ...

Kiel physics team observed extremely fast electronic changes in real time in a special material class

10-Jul-2020

In physics, they are currently the subject of intensive research; in electronics, they could enable completely new functions. So-called topological materials are characterised by special electronic properties, which are also very robust against external perturbations. This material group also ...
