Charge Berezinskii-Kosterlitz-Thouless transition in superconducting NbTiN films

Kavli Affiliate: Thomas Rosenbaum | Summary:A half-century after the discovery of the superconductor-insulator transition (SIT), one of the fundamental predictions of the theory, the charge Berezinskii-Kosterlitz-Thouless (BKT) transition that is expected to occur at the insulating side of the SIT, has remained unobserved. The charge BKT transition is a phenomenon dual to the vortex BKT […]

Hitomi X-ray studies of Giant Radio Pulses from the Crab pulsar

Kavli Affiliate: Shinichiro Takeda | Summary:To search for giant X-ray pulses correlated with the giant radio pulses (GRPs) from the Crab pulsar, we performed a simultaneous observation of the Crab pulsar with the X-ray satellite Hitomi in the 2 — 300 keV band and the Kashima NICT radio observatory in the 1.4 — 1.7 GHz […]

Linear feature detection algorithm for astronomical surveys – II. Defocusing effects on meteor tracks

Kavli Affiliate: Andrew Rasmussen | Summary:Given the current limited knowledge of meteor plasma micro-physics and its interaction with the surrounding atmosphere and ionosphere, meteors are a highly interesting observational target for high-resolution wide-field astronomical surveys. Such surveys are capable of resolving the physical size of meteor plasma heads, but they produce large volumes of images […]
