The Effects of Self-Shadowing by a Puffed up Inner Rim in Scattered Light Images of Protoplanetary Disks

Kavli Affiliate: Ruobing Dong | First 5 Authors: Ruobing Dong, , , , | Summary: We explore whether protoplanetary disks with self-shadowing from puffed up inner rims exhibit observable features in scattered light images. We use both self-consistent hydrostatic equilibrium calculations and parameterized models to produce the vertically puffed up inner rims. We find that, […]

Nanophotonic coherent light-matter interfaces based on rare-earth-doped crystals

Kavli Affiliate: Andrei Faraon | First 5 Authors: Tian Zhong, Jonathan M. Kindem, Evan Miyazono, Andrei Faraon, | Summary: Quantum light-matter interfaces (QLMIs) connecting stationary qubits to photons will enable optical networks for quantum communications, precise global time keeping, photon switching, and studies of fundamental physics. Rare-earth-ion (REI) doped crystals are state-of-the-art materials for optical […]

Multidimensional quasiballistic thermal transport in transient grating spectroscopy

Kavli Affiliate: Austin Minnich | First 5 Authors: Austin J. Minnich, , , , | Summary: Transient grating spectroscopy has emerged as a useful technique to study thermal phonon transport because of its ability to perform thermal measurements over length scales comparable to phonon mean free paths (MFPs). While several prior works have performed theoretical […]

A generalized enhanced Fourier law and underlying connections to major frameworks for quasi-ballistic phonon transport

Kavli Affiliate: John E. Bowers | First 5 Authors: Ashok T. Ramu, John E. Bowers, , , | Summary: An enhanced Fourier law (EFL) that accounts for quasi-ballistic phonon transport effects in a formulation entirely in terms of physical observables, is derived from the Boltzmann transport equation, assuming a gray population of quasi-ballistic phonon modes. […]

A Technique for Detection of PeV Neutrinos Using a Phased Radio Array

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 […]

A compact heat transfer model based on an enhanced Fourier law for analysis of frequency-domain thermoreflectance experiments

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 […]

Quantum dot nonlinearity through cavity-enhanced feedback with a charge memory

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 […]
