Combining our nano-SQUID on tip with scanning gate measurements in the quantum Hall phase of graphene we were able to measure and identify work and heat dissipation processes separately. [22] Probing the properties of a Mott insulator, a team of researchers from Boston College, MIT, and U.C. Santa Barbara has revealed an elusive atomic-scale magnetic signal in the unique material as it transitions from insulator to a metal, the team reported recently in the journal Nature Physics. [21] UC Santa Barbara engineer Galan Moody, an assistant professor of electrical and computer engineering, has proposed a solution to overcome the poor efficiency and performance of existing quantum computing prototypes that use light to encode and process information. [20] JILA physicists and collaborators have demonstrated the first next-generation "time scale"-a system that incorporates data from multiple atomic clocks to produce a single highly accurate timekeeping signal for distribution. [19] Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. [18] Our researchers were the first to produce these knots as part of a collaboration between Aalto University and Amherst College, U.S., and they have now studied how the knots behave over time. [17] The groundbreaking result sheds light on an elusive phenomenon whose existence, a natural outcome of the hundred-year-old theory of superconductivity, has long been speculated, but never actually observed. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions. [15] A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting states. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage.
