Kavli Affiliate: Alexander P. Ji | First 5 Authors: Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson, Sergey E. Koposov, Alex Drlica-Wagner | Summary: Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy’s gravitational field. Here, we analyze the morphology of the $300S$ stellar stream, which has an eccentric, retrograde orbit […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ruixiang Song, Ruixiang Song, , , | Summary: Metalenses, owing to their ultra-thin planar structures, present a promising solution for reducing endoscopic invasiveness. However, achieving high-quality imaging with minimal invasiveness (short focal length of metalens) remains a critical challenge. This paper presents a deep learning assisted metalens […]
Kavli Affiliate: Ting Xu | First 5 Authors: Zhiyi Chen, Zhiyi Chen, , , | Summary: Procrastination represents one of the most prevalent behavioral problems affecting individual health and societal productivity. Although it is often conceptualized as a form of self-control failure, its underlying neurocognitive mechanisms are poorly understood. A leading model posits that procrastination […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Juliana García-Mejía, Juliana García-Mejía, , , | Summary: We present a ground-based transit detection of HIP 41378 f, a long-period ($P = 542$ days), extremely low-density ($0.09 pm 0.02$ g cm$^-3$) giant exoplanet in a dynamically complex system. Using photometry from Tierras, TRAPPIST-North, and multiple LCOGT sites, […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Juliana García-Mejía, Zoë L. de Beurs, Patrick Tamburo, Andrew Vanderburg, David Charbonneau | Summary: We present a ground-based transit detection of HIP 41378 f, a long-period ($P = 542$ days), extremely low-density ($0.09 pm 0.02$ g cm$^{-3}$) giant exoplanet in a dynamically complex system. Using photometry from […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Toshiya Namikawa, , , | Summary: We present constraints on isotropic cosmic birefringence induced by axion-like particles (ALPs), derived from the analysis of cosmic microwave background (CMB) polarization measurements obtained with the high-frequency channels of Planck. Recent measurements report a hint of isotropic cosmic birefringence, […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Savdeep Sethi, , , | Summary: One of the key issues in holography is going beyond $mathrm{AdS}$ and defining quantum gravity in spacetimes with a null boundary. Recent examples of this type involve linear dilaton asymptotics and are related to the $T overline{T}$ deformation. We […]

Kavli Affiliate: Ronald Hanson | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: An efficient interface between a spin qubit and single photons is a key enabling system for quantum science and technology. We report on a coherently controlled diamond nitrogen-vacancy center electron spin qubit that is optically interfaced with an open microcavity. […]
Kavli Affiliate: Ronald Hanson | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Micrometer-scale thin diamond devices are key components for various quantum sensing and networking experiments, including the integration of color centers into optical microcavities. In this work, we introduce a laser-cutting method for patterning microdevices from millimeter-sized diamond membranes. The method […]
