Design and performance of a multi-terahertz Fourier transform spectrometer for axion dark matter experiments

Posted by April 14, 2021Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Kristin Dona, Jesse Liu, Noah Kurinsky, David Miller, Pete Barry | Summary: Dedicated spectrometers for terahertz radiation with [0.3, 30] THz frequencies using traditional optomechanical interferometry are substantially less common than their infrared and microwave counterparts. This paper presents the design and initial performance measurements of a […]

Characterization of Carrier Cooling Bottleneck in Silicon Nanoparticles by Extreme Ultraviolet (XUV) Transient Absorption Spectroscopy

Posted by April 12, 2021Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ilana J. Porter, Angela Lee, Scott K. Cushing, Hung-Tzu Chang, Justin C. Ondry | Summary: Silicon nanoparticles have the promise to surpass the theoretical efficiency limit of single-junction silicon photovoltaics by the creation of a "phonon bottleneck", a theorized slowing of the cooling rate of hot […]

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XIII. Large-scale Feedback and Star Formation in a Low-Luminosity Quasar at z = 7.07 on the Local Black Hole to Host Mass Relation

Posted by April 12, 2021Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Takuma Izumi, Yoshiki Matsuoka, Seiji Fujimoto, Masafusa Onoue, Michael A. Strauss | Summary: We present ALMA [CII] 158 $mu$m line and underlying far-infrared (FIR) continuum emission observations ($0”.70 times 0”.56$ resolution) toward HSC J124353.93$+$010038.5 (J1243$+$0100) at $z = 7.07$, the only low-luminosity ($M_{rm 1450} > -25$ […]

The Tiny (g-2) Muon Wobble from Small-$μ$ Supersymmetry

Posted by Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, | Summary: A new measurement of the muon anomalous magnetic moment has been reported by the Fermilab Muon g-2 collaboration and shows a $4.2sigma$ departure from the most precise and reliable calculation of this quantity in […]

Visual Vibration Tomography: Estimating Interior Material Properties from Monocular Video

Posted by April 6, 2021Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Berthy T. Feng, Alexander C. Ogren, Chiara Daraio, Katherine L. Bouman, | Summary: An object’s interior material properties, while invisible to the human eye, determine motion observed on its surface. We propose an approach that estimates heterogeneous material properties of an object from a monocular video of […]

EUSO-SPB2 sensitivity to macroscopic dark matter

Posted by April 2, 2021Chicago

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Thomas C. Paul, Sarah T. Reese, Luis A. Anchordoqui, Angela V. Olinto, Thomas Y. Chen | Summary: Macroscopic dark matter (or macro) provides a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy […]

Fast and Accurate Emulation of the SDO/HMI Stokes Inversion with Uncertainty Quantification

Posted by March 31, 2021Stanford

Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Richard E. L. Higgins, David F. Fouhey, Dichang Zhang, Spiro K. Antiochos, Graham Barnes | Summary: The Helioseismic and Magnetic Imager (HMI) onboard NASA’s Solar Dynamics Observatory (SDO) produces estimates of the photospheric magnetic field which are a critical input to many space weather modelling and […]

Competing correlated states around the zero field Wigner crystallization transition of electrons in two-dimensions

Posted by March 30, 2021Caltech

Kavli Affiliate: Joseph Falson | First 5 Authors: Joseph Falson, Inti Sodemann, Brian Skinner, Daniela Tabrea, Yusuke Kozuka | Summary: The competition between kinetic energy and Coulomb interactions in electronic systems can lead to complex many-body ground states with competing superconducting, charge density wave, and magnetic orders. Here we study the low temperature phases of […]
