ORNL neutron 'splashes' reveal signature of exotic particles

DOE/Oak Ridge National Laboratory

This Kitaev quantum spin liquid supports magnetic excitations equivalent to Majorana fermions–particles that are unusual in that they are their own antiparticles. Arnab Banerjee, the study’s lead author and a post-doctoral researcher at ORNL, explained that one way to observe spin liquid physics in such a material is to splash or excite the liquid using neutron scattering. The paper is published as Proximate Kitaev quantum spin liquid behaviour in a honeycomb magnet. The Spallation Neutron Source and the High Flux Isotope Reactor are DOE Office of Science User Facilities.
