Kavli Affiliate: Nathan Lewis | First 5 Authors: Wolfgang Altmannshofer, Nathan Lewis, , , | Summary: We use loop induced processes like meson oscillations and rare b hadron decays to determine the absolute values of the CKM matrix elements $|V_{ub}|$ and $|V_{cb}|$ and compare our results to the standard determinations based on inclusive and exclusive […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Minh Tran, Chong Zhang, Theodore Morin, Lin Chang, Sabyasachi Barik | Summary: Integrated photonics has profoundly impacted a wide range of technologies underpinning modern society. The ability to fabricate a complete optical system on a chip offers unrivalled scalability, weight, cost and power efficiency. Over the last […]
Kavli Affiliate: Changhuei Yang | First 5 Authors: Sylvain Gigan, Ori Katz, Hilton B. de Aguiar, Esben Ravn Andresen, Alexandre Aubry | Summary: The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow to understand and control light propagation in a complex […]
Kavli Affiliate: Amnon Yariv | First 5 Authors: Bin Zhang, Du Ran, Reuven Ianconescu, Aharon Friedman, Jacob Scheuer | Summary: We present a comprehensive theory for interrogation of the quantum state of a two-level system (TLS) based on a free-electron bound-electron resonant interaction scheme. The scheme comprises free electrons, whose quantum electron wavefunction is pre-shaped […]

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Taeyong Kim, Stavros X. Drakopoulos, Sara Ronca, Austin J. Minnich, | Summary: The thermal transport properties of oriented polymers are of fundamental and practical interest. High thermal conductivities ($gtrsim 50$ Wm$^{-1}$K$^{-1}$) have recently been reported in disentangled ultra-high molecular weight polyethylene (UHMWPE) films, considerably exceeding prior […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Osmond Wen, Taylor Aralis, Ritoban Basu Thakur, Bruce Bumble, Yen-Yung Chang | Summary: Detection of sub-GeV dark matter candidates requires sub-keV detector thresholds on deposited energy. We provide an update on a gram-scale phonon-mediated KID-based device that was designed for a dark matter search in this mass […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Zhi Chen, Alexander Ogren, Chiara Daraio, L. Catherine Brinson, Cynthia Rudin | Summary: Metamaterials are composite materials with engineered geometrical micro- and meso-structures that can lead to uncommon physical properties, like negative Poisson’s ratio or ultra-low shear resistance. Periodic metamaterials are composed of repeating unit-cells, and geometrical […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, Xiujun Shu, | Summary: There are many challenging problems in the person re-identification (ReID) task, such as the occlusion and scale variation. Existing works usually tried to solve them by employing a one-branch network. This one-branch network needs to be robust […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, Xiujun Shu, | Summary: Unsupervised video person re-identification (reID) methods usually depend on global-level features. And many supervised reID methods employed local-level features and achieved significant performance improvements. However, applying local-level features to unsupervised methods may introduce an unstable performance. To […]
