Technology based on the use of light – its generation, harvesting and manipulation – has transformed modern life. For example, we use lasers for surgery and manufacturing, solar panels to sustainably produce electricity, and fiber optics to send internet signals around the world. As both the demand for and complexity of photonic devices grow, there … Continued
Our research group explores new physical phenomena in atomically thin materials and their heterostructures. We study a wide range of materials with very different properties, including semiconductors, superconductors and magnets etc. We stack them together to form heteostructures, and make electronics, optoelectronics and optomechanical devices. To explore new phenomena, we also develop new measurement and … Continued
Our lab studies atomic and molecular gases cooled to a few billionths of a degree above absolute zero. At these temperatures, the gases enter a regime of quantum degeneracy and are useful for highly controlled studies of quantum many-body phenomena. By trapping the particles in tailored optical potentials, our group is able to engineer synthetic … Continued
My research interests lie in low dimensional electronic systems, where the interplay of topological order and symmetry breaking can lead to new states matter with novel quantum properties. My goal is to engineer quantum electronic devices that harness the full potential of topological systems—long-predicted but never observed—to protect quantum information from environmental decoherence. While such … Continued
My research interest is in the study of novel electronic systems where strong interactions lead to new states of matter, together with the exploitation of these new phases for technological applications. An exciting new opportunity in this effort is our ability to fabricate double-layer structures consisting of two closely-spaced two-dimensional materials. The wide range of … Continued
I am interested in developing laser-based spectroscopic techniques to search for novel quantum phases of matter in solids, with an eye towards nano-electronics and quantum information technologies. I am particularly interested in topological, strongly correlated and out-of-equilibrium driven phases of matter.
My research investigates physical phenomena that grant access to phonons—or quantum particles of sound—as the basis for sensitive metrology and new forms of classical and quantum information processing. At low temperatures, phonons have greatly extended coherence times and they exhibit many intriguing properties; phonons can interact strongly with atom-like defect centers, they can be converted … Continued
I am a theortical physicist. My research aims to reveal and elucidate strange quantum properties of solids that may provide the basis for new technologies. My research group made contributions to the field of topological quantum materials, and introduced the concept of topological crystalline insulators. We introduced the first realistic material platform for creating Majorana … Continued
Interfaces between semiconductors play an essential role in many applications that seem indispensable to us, such as mobile communication, barcode readers and laser pointers. Recently, a new class of materials based on oxides has seen a similar explosion of interest as semiconductors 50 years ago. These complex oxides exhibit a rich variety of functional properties … Continued
Our research group synthesizes physical and evolutionary insights to discover novel biophysical mechanisms in evolutionarily diverse systems. Examples include solar transformer and radiative cooling functions in giant clams, phase-transition driven micropattern formation in plants and insects, light-guided camouflage in squid, and patchy-colloidal self-assembly for gradient-index optics in squid.
