Ultra-sensitive and Wide Bandwidth Thermal Measurements of Graphene at Low Temperatures

Kavli Affiliate: Keith Schwab | First 5 Authors: , , , , | Summary: Graphene is a material with remarkable electronic properties and exceptional thermal transport properties near room temperature, which have been well examined and understood. However at very low temperatures the thermodynamic and thermal transport properties are much less well explored and somewhat […]

AVAST Survey 0.4-1.0 μm Spectroscopy of Igneous Asteroids in the Inner and Middle Main Belt

Kavli Affiliate: Geza Gyuk | First 5 Authors: Michael Solontoi, Mark Hammergren, Geza Gyuk, Andrew Puckett, | Summary: We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids for follow up by nature of […]

Reduction of thermal fluctuations in a cryogenic laser interferometric gravitational wave detector

Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: Takashi Uchiyama, Shinji Miyoki, Souichi Telada, Kazuhiro Yamamoto, Masatake Ohashi | Summary: The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first time a reduction in a mirror’s thermal fluctuation in a GW detector […]

Irregular transcription dynamics for rapid production of high-fidelity transcripts

Kavli Affiliate: Martin Depken | First 5 Authors: Martin Depken, Juan M. R. Parrondo, Stephan W. Gril, , | Summary: Both genomic stability and sustenance of day-to-day life rely on efficient and accurate readout of the genetic code. Single-molecule experiments show that transcription and replication are highly stochastic and irregular processes, with the polymerases frequently […]

Atomic-resolution spectroscopic imaging of ensembles of nanocatalyst particles across the life of a fuel cell

Kavli Affiliate: Lena Fitting Kourkoutis | First 5 Authors: Huolin L. Xin, Julia A. Mundy, Zhongyi Liu, Randi Cabezas, Robert Hovden | Summary: The thousandfold increase in data-collection speed enabled by aberration-corrected optics allows us to overcome an electron microscopy paradox – how to obtain atomic-resolution chemical structure in individual nanoparticles, yet record a statistically […]

Measuring the spatial extent of individual localized photonic states

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Marko Spasenovic, Daryl M. Beggs, Philippe Lalanne, Thomas F. Krauss, L. | Summary: We measure the spatial extent of individual localized photonic states in a slow-light photonic crystal waveguide. The size of the states is measured by perturbing each state individually through a local electromagnetic interaction with […]

A photonic crystal nanocavity laser in an optically very thick slab

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Jingqing Huang, Axel Scherer, , | Summary: A photonic crystal (PhC) nanocavity formed in an optically very thick slab can support reasonably high-Q modes for lasing. Experimentally, we demonstrate room-temperature pulsed lasing operation from the PhC dipole mode emitting at 1324 nm, which is fabricated […]

Suzaku Observations of 4U 1957+11: Potentially the Most Rapidly Spinning Black Hole in (the Halo of) the Galaxy

Kavli Affiliate: Norbert Schulz | First 5 Authors: Michael A. Nowak, Joern Wilms, Katja Pottschmidt, Norbert Schulz, Dipankar Maitra | Summary: We present three Suzaku observations of the black hole candidate 4U 1957+11 (V1408 Aql) — a source that exhibits some of the simplest and cleanest examples of soft, disk-dominated spectra. 4U 1957+11 also presents […]

Ion association in low-polarity solvents: comparisons between theory, simulation, and experiment

Kavli Affiliate: Jos W. Zwanikken | First 5 Authors: Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken, René van Roij, Marjolein Dijkstra | Summary: The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The specific case of the restricted primitive model […]
