A team of Japanese researchers has discovered a method to control Kelvin wave excitation in superfluid helium-4. This breakthrough can refine our understanding of how energy moves in quantum ...

[Derek] puts the final product to use for a Kelvin measurement of a 0.47-Ω 1% resistor at the end of the video. We’re glad to see [Derek] in action; you may recall his earlier video about ...

But if you watch [tomtektest’s] recent video, you’ll learn they are really Kelvin probes. Kelvin probes are a special type of probe for making accurate resistance measurements using four wires ...

The Kelvin method has extremely high surface sensitivity (<0.1 meV, typically corresponding to 10-3of an adsorbate layer) and is completely non-damaging, even to the most sensitive adsorbates. It ...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing ...
