My group studies ultracold gases of atoms and molecules. At temperatures a million times colder than interstellar space and at densities a million times thinner than air, quantum mechanics takes center stage. Atoms behave as waves, they interfere like laser light, and form novel states of matter, such as Bose-Einstein condensates. With attractive interactions, fermionic … Continued
My research focuses on the theory of strongly interacting and disordered systems. I am interested in new kinds of correlated states of matter that arise in various interacting many-body systems, especially when their understanding requires new theoretical tools and techniques. In particular, I worked on superconductivity in new regimes, far from equilibrium many-body systems, mesoscopic … Continued
My research mainly focuses on quantum many-body systems with strong interaction and strong quantum fluctuation. In the last 20 years, our field has made tremendous progresses towards understanding and classifying exotic states of matter under extreme conditions. But we believe we have only understood the tip of the iceberg in this rapidly developing field. Most … Continued
I work in Condensed Matter Theory with the following materials: Quasi-one-dimensional organic conductors, such as (TMTSF)2X. I worked on theories of the angular magnetoresistance oscillations (AMRO), the midgap Andeev bound states for triplet p-wave superconductivity, the Magnetic-Field-Induced Spin-Density Wave (FISDW) and the quantum Hall effect (QHE); – Cuprate high-temperature superconductors; – Ruthenate superconductors Sr2RuO4. I … Continued
My principal research field is experimental condensed matter physics, and my research group at Caltech currently focuses on scientific and technological topics of correlated electrons (e.g., high-temperature superconductors; novel magnetic systems), topological materials (e.g., topological insulators and superconductors; topological states and channels for quantum information), low-dimensional systems (e.g., van der Waals materials, including graphene, h-BN … Continued
My research focuses on emerging phenomena in low dimensional materials, such as Luttinger liquid in one dimensional metal, quantum critical behavior and electron second sound in graphene, spin and Valley degrees of freedoms in two dimensional heterostructures, and spatial-temporal imaging of elementary excitations.
My research involves experiments with laser-cooled atoms in optical lattices and other light traps. My group uses cold, trapped atoms to make precise measurements of fundamental constants and to test fundamental symmetries. We also use atoms as model systems to address issues in atomic physics, condensed-matter physics, quantum mechanics, and statistical mechanics. Current research includes: … Continued
Studies of unconventional superconductors and novel magnetic systems by muon spin relaxation, neutron scattering and phenomenology
My primary area of research is string theory. String theory is at the center of efforts by theoretical physicists to find a unified fundamental theory of nature— that is, all particles and the forces between them—in a consistent quantum theory. In a single theory, one studies the mysteries of confinement of quarks inside atomic nuclei, … Continued
My research field is string theory, quantum gravity, and conformal field theory. My most recent research is focused on the quantum theory of black holes, and its connection to quantum information theory, entanglement, and quantum chaos. Among other results, my recent work unearthed a link between how black holes store information and the properties of … Continued
