The Hayden and Sonier groups at Simon Fraser University use magnetic resonance techniques as a sensitive probe of condensed matter systems. The research program is very broad, ranging from precise tests of fundamental symmetries in nature, to probes of magnetism at surfaces. The Hayden group has recently made advances in the new area of "spin turbulence", showing that in some circumstances the chaotic motion of nuclear spins can be reversed. This has enormous potential for future research, not least because it will lead to improvements in the resolution of state-of-the-art commercial magnetic resonance spectrometers. The Sonier group, in collaboration with Hayden, have developed an extensive set of tools for carrying out surface-sensitive magnetic resonance experiments, that will have important applications in materials science.

西蒙弗雷泽大学的海登和索尼耶小组使用磁共振技术作为凝聚态系统的灵敏探针。 研究计划非常广泛，从自然界基本对称性的精确测试到表面磁性的探测。 海登小组最近在“自旋湍流”这一新领域取得了进展，表明在某些情况下，核自旋的混沌运动是可以逆转的。 这对未来的研究具有巨大的潜力，尤其是因为它将导致最先进的商业磁共振光谱仪分辨率的提高。 Sonier小组与Hayden合作开发了一套广泛的工具，用于进行表面敏感的磁共振实验，这将在材料科学中有重要的应用。
