Neutrons are deeply penetrating probes which allow for the study of the internal characteristics of materials.  By utilizing interference phenomena one can probe aspects of physics to a degree not possible by other methods.     We have recently developed two new methods in the area of material research using neutrons.   In Pendellosung interference, neutron waves inside a periodic lattice are sensitive not just to structure dynamics but also of the neutron itself through its own quark structure. Pendellosung interference is a highly precise technique and has already been shown to place limits on Beyond the Standard Model physics at the few nanometer range.    Additionally, we can now generate neutron beams carrying orbital angular momentum (OAM). Quantum states with OAM are robust against noise and sensitive to chiral structure.   These new techniques allow our program to explore new physics, provide high precision nuclear and structural data, explore other types of structured waves,  and measure topological samples that may find use in quantum computing.
