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
My quantum information interests center on the use of highly excited atoms for conditional quantum manipulation; the quantum state of one atom evolves in controllable manner that is dependent of the state of a single other atom 10 microns away. Such processes form key building blocks for quantum computers and quantum optics. In the area … Continued
I have been fascinated with the problem of insect flight: how do insects fly, why do they fly the way they do, and how can we infer their ‘thoughts’ from their flight dynamics? Starting from the Navier-Stokes equations governing the unsteady aerodynamics of flapping flight, we worked to build a theoretical framework for computing flight, … Continued
Studies of unconventional superconductors and novel magnetic systems by muon spin relaxation, neutron scattering and phenomenology
I am primarily a quantum condensed matter physicist with a focus on “strongly correlated” systems, although inevitably I also work on problems in classical statistical mechanics as do all members of my tribe. The term strongly correlated refers to materials in which the interactions among the electrons are important, even for a qualitative understanding of … Continued
I perform experiments with ultracold atomic gases and optical fields to study a range of phenomena in quantum science, including topics from many-body and condensed-matter physics, matter-wave optics, quantum states of light, and precision and quantum measurement.
My lab focuses on the study of novel ground states and functional properties in condensed matter systems synthesized via atomically precise thin film deposition techniques. These model systems often stabilize ground states and functional properties not observable in the bulk. I have a particular interest in strongly correlated complex oxide thin films and heterostructures, including … Continued
For most of my career, I have been involved with atomic physics and condensed matter physics. As a graduate student, I discovered the phenomenon of “nuclear spin noise”. When nuclear spins are placed in a pickup coil connected to a resonant circuit, there was random noise in the coil due to fluctuations of the nuclear … Continued
My research focuses on the development of superconducting devices for quantum information processing, which are leading to revolutionary advances in computing. My group is a leader in the development of solid-state quantum bits (qubits) for quantum computing, and the advancement of their performance to practical levels. Together with collaborators at Yale, Professors Michel Devoret and … Continued
