This worked concerned the development of a new kind of spectrometer for characterization of materials with interesting quantum mechanical correlations. Quantum materials as such are one of the most interesting areas of modern condensed matter physics. Strong interactions and topological effects conspire to give novel material properties that have no precedent. They are likely to find use in the next generation of devices. The science pursued in the context of this research will enable these advances. However, despite the overwhelming interest in these systems, it is increasingly clear that we do not have the experimental tools to properly characterize many of their properties. For instance, one of the most notable aspects of many topological spin systems is that they possess fractionalized particles. In such systems, the conventional particles and excitations of the material fractionalize into multiple parts. In 1D this fractionalization is quite natural, but in higher dimensional spin-liquids it is controversial. However even in 1D, we do not have the proper techniques to measure many of the properties of fractionalized particles and manipulate them. In conventional linear spectroscopy, we measure only broad continuum lineshapes in candidate systems that prevent the direct detection of individual particles and obscure their properties if they exist.
