Pulsed Strain Offers High Sensitivity for Measuring Nematic Susceptibility
Former REU student Caleb Williams worked with Cameron Chaffey to develop a novel method to measure the nematic susceptibility using NMR. In this case, positive and negative strain is pulsed in synchrony with the NMR radiofrequency pulses. As a result, the NMR spin echo acquires a phase that depends on the nematic response. This approach improves the sensitivity by three orders of magnitude, and their work was featured as an Editor’s Pick!
