Helium Puddles Near Absolute Zero

Helium has always been a bit of an outsider on the Periodic Table. Its two isotopes, helium-3 and helium-4, remain liquid down to absolute zero and have the lowest liquefaction temperature among the gases. These features can be traced to the high zero-point energy relative to their attractive potential. In two dimensions, helium4 will form a liquid and become superfluid at temperatures that dep...

Helical edge resistance introduced by charge puddles.

We study the influence of electron puddles created by doping of a 2D topological insulator on its helical edge conductance. A single puddle is modeled by a quantum dot tunnel coupled to the helical edge. It may lead to significant inelastic backscattering within the edge because of the long electron dwelling time in the dot. We find the resulting correction to the perfect edge conductance. Gene...

Exploitation of puddles for breakthroughs in claustrum research

Since its first identification as a thin strip of gray matter enclosed between stretches of neighboring fiber bundles, the claustrum has been considered impossible to study by many modern techniques that need a certain roominess of tissue for their application. Known as the front wall, vormauren in German from 1822, and still called avant-mur in French, we here propose a means for breaking into...

Role of Earthworms in Vermitechnology

Earthworms are essential detritus feeders that play a vital role in the process of decomposition of organic matter and soil metabolism. They are referred to as indicators of soil health. The complex process of partial breakdown of organic matter and mixing with mucous and gut microbial flora in the form of earthworm cast results in the enhancement of soil fertility status. They influence the so...
