If people bump into one another too often at a buildings entrance, the owner could opt to build a larger doorway. But physicists from the RIKEN Advanced Science Institute in Wako have shown that this intuitive solution may not always workespecially at the nanoscale. The team of David Rees, Hiroo Totsuji, and Kimitoshi Kono has discovered that when crystalline electrons pass through a narrow nanoconstriction, particle movement sometimes decreases as the bottleneck gets wider.
