My research is focused on using spin-polarized atoms for tests of fundamental symmetries of physics laws and for development of atomic sensors with interdisciplinary applications. My group uses large ensembles of polarized atoms with very long spin coherence time to make sensitive measurements with unprecedented energy resolution. The results of our research include best tests … Continued
My work deals generally with strongly interacting quantum field theories (QFTs). I am interested in the study of their general properties and structures, as well as in their applications to systems of condensed matter or statistical mechanics, some of high experimental interest. Most of my work uses non-perturbative techniques such as conformal invariance, integrability and … Continued
I study interacting quantum spin systems using nuclear magnetic resonance (NMR). Nuclear spins in hard, insulating, crystalline solids stand apart form all other quantum many-body systems as far better isolated from environmental degrees of freedom. Even at high temperatures where the system is far from its ground state, these systems retain fully-coherent quantum dynamics over … Continued
My research group’s recent works focus on the role of quantum entanglement in quantum many-body physics and quantum gravity. We helped relating holographic duality with tensor network states, a geometrical representation of quantum many-body states. We have also worked on topological states of matter. Our work pointed out the relation between topological insulators in three … Continued
My research is at the nexus of biology, physics and technology development. My group has invented many measurement tools for biology, including new DNA sequencing technologies that have enabled rapid analysis of the human genome and microfluidic automation that allows scientists to efficiently isolate individual cells and decipher their genetic code. Our lab is also … Continued
My theoretical research interests span a broad spectrum of classical and quantum condensed matter. These range from entropy-dominated liquid crystals, colloids, membranes, rubber and other “soft” matter to quantum matter, such as superconductors, magnets, degenerate atomic gases, quantum Hall and other topological states of matter. I aim to understand the nature of phases and phase … Continued
My research group uses electronic, magnetic, optical, and mechanical measurements to study physical mechanisms by which nanometer-scale materials and devices can exhibit different behaviors than bulk materials. One focus of current research is based on controlling electron spins in nanoscale devices, and using spins to exert torques on magnetic materials to make more efficient magnetic … Continued
I lead an experimental group that works with trapped molecular ions. By laser-cooling co-trapped atomic ions, my group can sympathetically cool the molecular ions to milliKelvin temperatures, where velocities and environmental interactions are reduced and where novel molecular control becomes possible. Applications of the research range from particle physics to chemistry to astrophysics.
My research group focuses on the transport properties of nanoscale quantum materials. Semiconductor quantum dots are used to isolate single electron spins, which exhibit long quantum coherence times. These systems allow quantum mechanics to be harnessed in a solid state environment for the implementation of elementary quantum gates. Our team uses nanofabrication to create artificially … Continued
Our research applies the experimental tools of nanoscale science to address open questions in condensed matter physics. One research direction uses electronic transport and noise techniques to explore the nature of the current-carrying excitations in strongly correlated materials – systems in which electron-electron interactions cannot be neglected and the standard model of conventional metals appears … Continued
