Quantum Fractionalization (image) Rice University Share Print E-Mail Caption In an ultracold atomic experiment proposed by Rice University physicists Matthew Foster and Seth Davis, quantum fractionalization would be observed by density waves propagating in the direction of 1D quantum waveguides (left). In the absence of fractionalization (right), density waves would spread in a perpendicular direction. Credit Matthew Foster/Rice University Usage Restrictions Credit must be used.
