Effects of mirror birefringence and its fluctuations to laser interferometric gravitational wave detectors

Posted by dbos Caltech

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Yuta Michimura, Haoyu Wang, Francisco Salces-Carcoba, Christopher Wipf, Aidan Brooks | Summary: Crystalline materials are promising candidates as substrates or high-reflective coatings of mirrors to reduce thermal noises in future laser interferometric gravitational wave detectors. However, birefringence of such materials could degrade the sensitivity of gravitational […]

Echoes Beyond Points: Unleashing the Power of Raw Radar Data in Multi-modality Fusion

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yang Liu, Feng Wang, Naiyan Wang, Zhaoxiang Zhang, | Summary: Radar is ubiquitous in autonomous driving systems due to its low cost and good adaptability to bad weather. Nevertheless, the radar detection performance is usually inferior because its point cloud is sparse and not accurate due to […]

Unravelling the Mechanics of Knitted Fabrics Through Hierarchical Geometric Representation

Posted by klaurent Harvard

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 organization 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 Cornell

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 […]

Complex magnetic and spatial symmetry breaking from correlations in kagome flat bands

Posted by klaurent Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yu-Ping Lin, Chunxiao Liu, Joel E. Moore, , | Summary: We present the mean-field phase diagram of electrons in a kagome flat band with repulsive interactions. In addition to flat-band ferromagnetism, the Hartree-Fock analysis yields cascades of unconventional magnetic orders driven by onsite repulsion as filling […]
