Sparse identification of multiphase turbulence closures for coupled fluid--particle flows

Autor: Beetham, S., Fox, R. O., Capecelatro, J.

In this work, model closures of the multiphase Reynolds-Average Navier-Stokes (RANS) equations are developed for homogeneous, fully-developed gas--particle flows. To date, the majority of RANS closures are based on extensions of single-phase turbulen

Multi-Chroic Feed-Horn Coupled TES Polarimeters

Autor: McMahon, J., Beall, J., Becker, D., Cho, H. M., Fox, R. Datta. A., Halverson, N., Hubmayr, J., Irwin, K., Nibarger, J., Niemack, M., Smith, H.

Multi-chroic polarization sensitive detectors offer an avenue to increase both the spectral coverage and sensitivity of instruments optimized for observations of the cosmic-microwave background (CMB) or sub-mm sky. We report on an effort to adapt the

Making optical atomic clocks more stable with $10^{-16}$ level laser stabilization

Autor: Jiang, Y. Y., Ludlow, A. D., Lemke, N. D., Fox, R. W., Sherman, J. A., Ma, L. -S., Oates, C. W.

The superb precision of an atomic clock is derived from its stability. Atomic clocks based on optical (rather than microwave) frequencies are attractive because of their potential for high stability, which scales with operational frequency. Neverthel
