Biography
Dr. Hu's main research area is condensed matter theory, but he also maintains a strong side interest in light scattering, quantum computing, quantum optics, theory of networks, and various condensed phases of trapped and cooled atoms. Most of his past research publications are focused on the space- and/or time-dependent properties of superconductors and superfluid Helium-3. In the past, he has investigated surface superconductivity; flux-flow-related transport properties and transport entropy of Type II superconductors; microscopic derivation of the dynamic equations for inhomogeneous superconductors; coexistence of superconductivity and ferromagnetism; non-linear magnetic, hydrodynamic, and textual properties of superfluid Helium-3; superconducting networks; two-dimensional superfluidity; and granular superconductors; as well as light scattering from a non-ellipsoidal-shaped dielectric particle with a size of the order of the light wavelength, and the related symmetry properties. His more recent interest has been concentrated on the anisotropy- and pairing-symmetry-related properties of cuprate high-temperature and other unconventional superconductors, as well as the pairing of fermions with mismatched Fermi surfaces, including, but not limited to, the so-called FFLO (Fulde-Ferrell-Larkin-Ovchinnikov) state. Very recently, he has also branched into an interdisciplinary research area, viz., the statistical-mechanical theory of networks, which has technological, social, biological, and medical applications, since networks can practical appear everywhere, for example, internet, world-wide-web, epidemic, neuro-networks, protein folding, etc., etc., etc. In addition, he has also conceived a conceptual generalization of spin ice, which he has coined the name color-tripole ice. Spin ice has magnetic monopole excitations which have been observed. Color-Tripole ice will have color charge excitations, much like the color charges introduced in high energy physics, except that here the color charges are Abelian.
