We have experimentally observed a collisional frequency shift of trapped ultracold fermions. We probe the distinguishing features of s-wave collisional frequency shifts of fermions by stepping the ...

Well, it's July 12, which means (a) the Steam Summer Sale is over and (b) it's really hot outside in the northeastern U.S.

We review recent progress in our theoretical understanding of strongly correlated fermion systems in the presence of disorder. Results were obtained by the application of a powerful nonperturbative ...

However, the problem with string theory is that it is so flexible that it can explain almost anything, making it nearly ...

The fusion of non-Abelian anyons or topological defects is a fundamental operation in measurement-only topological quantum computation. In topological superconductors, this operation amounts to a ...

Yet researchers at Leibniz University Hannover have now shown that universal embezzlement emerges in all critical fermion chains, meaning one-dimensional fermion systems at quantum phase transitions.
