Considerable efforts are currently devoted to the preparation of ultracold neutral atoms in the strongly correlated quantum Hall regime. However, the necessary angular momentum is very large and in experiments with rotating traps this means spinning freq
(radio) telescopes. In this event, our tiny, but extremely hot, universe underwent an “inflationary epoch”, expanding from the size of an atom to that of a grapefruit in the first fewfemtoseconds after the Bang. And it continues to inflate (and even accelerate*), 13.7 billion years ...
We have measured the winding number probability distribution for a range of quench rates, with a quench protocol using simultaneous forced evaporation and interaction ramps to achieve faster effective quench rates with less atom loss than a purely evaporative quench. We find that for the fastest ...
Their new reaction allows them to incorporate a single carbon atom into the framework of carbon-based rings to adjust the ring size from five to six-membered rings. In the past, this was only possible with nitrogen atoms. “By contrast, inserting a single carbon atom into an all-carbon rin...
The fused heterocyclic rings to be discussed here have normally been produced by an intramolecular cyclization of an N(6)-, N(2)- or S-substituent onto a ring nitrogen atom in the purine nucleus and are mainly five- or six-membered systems; cyclonucleosides such as (210) are of ...
