Freeform three-mirror anastigmatic large-aperture telescope and receiver optics for CMB-S4

Posted by July 24, 2023Chicago

Kavli Affiliate: Bradford Benson | First 5 Authors: Patricio A. Gallardo, Roberto Puddu, Kathleen Harrington, Bradford Benson, John Carlstrom | Summary: CMB-S4, the next-generation ground-based cosmic microwave background (CMB) observatory, will provide detailed maps of the CMB at millimeter wavelengths to dramatically advance our understanding of the origin and evolution of the universe. CMB-S4 will […]

The Impact of Beam Variations on Power Spectrum Estimation for 21 cm Cosmology II: Mitigation of Foreground Systematics for HERA

Posted by klaurent July 24, 2023MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Honggeun Kim, Nicholas S. Kern, Jacqueline N. Hewitt, Bang D. Nhan, Joshua S. Dillon | Summary: One key challenge in detecting 21 cm cosmological signal at z > 6 is to separate the cosmological signal from foreground emission. This can be studied in a power spectrum […]

Fast and Fourier: Extreme Mass Ratio Inspiral Waveforms in the Frequency Domain

Posted by dbos July 24, 2023MIT

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lorenzo Speri, Michael L. Katz, Alvin J. K. Chua, Scott A. Hughes, Niels Warburton | Summary: Extreme Mass Ratio Inspirals (EMRIs) are one of the key sources for future space-based gravitational wave interferometers. Measurements of EMRI gravitational waves are expected to determine the characteristics of their […]

Unravelling the Mechanics of Knitted Fabrics Through Hierarchical Geometric Representation

Posted by dbos July 23, 2023Harvard

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Xiaoxiao Ding, Vanessa Sanchez, Katia Bertoldi, Chris H. Rycroft, | Summary: Knitting interloops one-dimensional yarns into three-dimensional fabrics that exhibit behaviours beyond their constitutive materials. How extensibility and anisotropy emerge from the hierarchical organisation of yarns into knitted fabrics has long been unresolved. We sought to unravel […]

Observation of spin polarons in a frustrated moiré Hubbard system

Posted by klaurent July 23, 2023Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Wenjin Zhao, Bowen Shen, Patrick Knüppel, Kenji Watanabe | Summary: The electron’s kinetic energy plays a pivotal role in magnetism. While virtual electron hopping promotes antiferromagnetism in an insulator, the real process usually favors ferromagnetism. But in kinetically frustrated systems, such as hole doped triangular […]
