E/B mode decomposition of HSC-Y1 cosmic shear using COSEBIs: cosmological constraints and comparison with other two-point statistics

Posted by klaurent Tokyo

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Takashi Hamana, Chiaki Hikage, Masamune Oguri, Masato Shirasaki, Surhud More | Summary: We perform a cosmic shear analysis of HSC survey first-year data (HSC-Y1) using Complete Orthogonal Sets of E/B-Integrals (COSEBIs) to derive cosmological constraints. We compute E/B-mode COSEBIs from cosmic shear two-point correlation functions measured on […]

Dielectric catastrophe at the Mott and Wigner transitions in a moiré superlattice

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Yanhao Tang, Jie Gu, Song Liu, Kenji Watanabe, Takashi Taniguchi | Summary: The metal-insulator transition (MIT) driven by electronic correlations is a fundamental and challenging problem in condensed-matter physics. Particularly, whether such a transition can be continuous remains open. The emergence of semiconducting moir’e materials with continuously […]

Designing Berry curvature dipoles and the quantum nonlinear Hall effect at oxide interfaces

Posted by klaurent Delft

Kavli Affiliate: Gary A. Steele | First 5 Authors: Edouard Lesne, Yildiz G. Saǧlam, Raffaele Battilomo, Thierry C. van Thiel, Ulderico Filippozzi | Summary: Quantum materials can display physical phenomena rooted in the geometric properties of their electronic wavefunctions, and governed by an emergent magnetic field known as Berry curvature. In materials with acentric crystalline […]

On the on-shell equivalence of general relativity and Holst theories with nonmetricity, torsion, and boundaries

Posted by klaurent MIT

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We study a generalization of the Holst action where we admit nonmetricity and torsion in manifolds with timelike boundaries (both in the metric and tetrad formalism). We prove that its space of […]

Modular representation and control of floppy networks

Posted by klaurent Harvard

Kavli Affiliate: L. Mahadevan | First 5 Authors: Siheng Chen, Fabio Giardina, Gary P. T. Choi, L. Mahadevan, | Summary: Geometric graph models of systems as diverse as proteins, robots, and mechanical structures from DNA assemblies to architected materials point towards a unified way to represent and control them in space and time. While much […]

High-field transport and hot electron noise in GaAs from first principles: role of two-phonon scattering

Posted by klaurent Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Peishi S. Cheng, Shi-Ning Sun, Alexander Y. Choi, Austin J. Minnich, | Summary: High-field charge transport in semiconductors is of fundamental interest and practical importance. While the ab initio treatment of low-field transport is well-developed, the treatment of high-field transport is much less so, particularly for […]

Monitoring inner regions in the RY Tau jet

Posted by klaurent MIT

Kavli Affiliate: Moritz Guenther | First 5 Authors: Taichi Uyama, Michihiro Takami, Gabriele Cugno, Vincent Deo, Olivier Guyon | Summary: We present multi-epoch observations of the RY~Tau jet for H$alpha$ and [ion{Fe}{2}] 1.644 micron~emission lines obtained with Subaru/SCExAO+VAMPIRES, Gemini/NIFS, and Keck/OSIRIS in 2019–2021. These data show a series of four knots within 1$arcsec$ consistent with […]

Using the Sun to Measure the Primary Beam Response of the Canadian Hydrogen Intensity Mapping Experiment

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Kevin Bandura, Anja Boskovic, Jean-François Cliche | Summary: We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift scan instrument, we rely on the seasonal […]
