Of particular interest are NMR 1/T1 relaxation rates, which measure how fast energy stored in magnetic nuclei is transferred to surrounding electrons.   This thesis develops a detailed, quantitative theory of NMR 1/T1 relaxation rates, and shows for the first time how they could be used to measure the speed at which energy travels in a wide range of magnetic materials.   This theory is used to make predictions for"Quantum Spin Nematics", an exotic form of quantum order analogous to a liquid crystal.  In order to do so, it is first necessary to unravel how spin nematics transport energy. This thesis proposes a new way to do this, based on the description of quarks in high-energy physics.   Experiments to test the ideas presented are now underway in laboratories across the world.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Nuclear magnetismNuclear physicsNuclear magnetism.Nuclear physics.530543.66Smerald Andrew871952MiAaPQMiAaPQMiAaPQBOOK9910437982803321Theory of the Nuclear Magnetic 11946825UNINA
