Kavli Affiliate: Chihway Chang | First 5 Authors: Chihway Chang, Christian Monstein, Alexandre Refregier, Adam Amara, Adrian Glauser | Summary: We present a multi-frequency far-field beam map for the 5m dish telescope at the Bleien Observatory measured using a commercially available drone. We describe the hexacopter drone used in this experiment, the design of the […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: Combining a variety of results in string theory and general relativity, a picture of the black hole interior is developed wherein spacetime caps off at an inner horizon, and the inter-horizon region is occupied by a Hagedorn gas […]

Kavli Affiliate: Subo Dong | First 5 Authors: Warren Skidmore, Bob Kirshner, David Andersen, Gelys Trancho, Scot Kleinman | Summary: The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the most profound questions about the universe. From unraveling the mysteries […]

Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: Demitry Farfurnik, Andrey Jarmola, Linh M. Pham, Zhi-Hui Wang, Viatcheslav V. Dobrovitski | Summary: We demonstrate significant improvements of the spin coherence time of a dense ensemble of nitrogen-vacancy (NV) centers in diamond through optimized dynamical decoupling (DD). Cooling the sample down to $77$ K suppresses […]
Kavli Affiliate: Abigail Vieregg | First 5 Authors: A. G. Vieregg, K. Bechtol, A. Romero-Wolf, , | Summary: The detection of high energy neutrinos ($10^{15}-10^{20}$ eV or $1-10^{5}$ PeV) is an important step toward understanding the most energetic cosmic accelerators and would enable tests of fundamental physics at energy scales that cannot easily be achieved […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Ashok T. Ramu, John E. Bowers, , , | Summary: A recently developed enhanced Fourier law is applied to the problem of extracting thermal properties of materials from frequency-domain thermoreflectance (FDTR) experiments. The heat transfer model comprises contributions from two phonon channels; one a high-heat-capacity diffuse […]
Kavli Affiliate: Larry Coldren | First 5 Authors: Morten P. Bakker, Thomas Ruytenberg, Wolfgang Loffler, Ajit V. Barve, Larry Coldren | Summary: In an oxide apertured quantum dot (QD) micropillar cavity-QED system, we found strong QD hysteresis effects and lineshape modifications even at very low intensities corresponding to less than 0.001 intracavity photons. We attribute […]
