Resonant x-ray diffraction and the observation of strange quantities

Condensed matter physics has a growing reputation for providing an opportunity to observe exotic particles and states of matter that have an analogue in other areas of physics. Examples of this include the observation of Dirac strings and magnetic monopoles in spin-ice materials [1], spinon / holon separation in gated nanowires [2], and toroidal moments (anapoles) in the ubiquitous cuprates [3]. Resonant X-ray Diffraction (RXD) is well suited to the observation of a variety of quantities that behave differently under time reversal, coordinate inversion, and rotation [4]. It is possible to distinguish between competing orders and we have determined the orbital order in RB2C2, including higer order terms (as illustrated on the cover page) [5,6]
