Quantum states interrogation using a pre-shaped free electron wavefunction

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 […]

Origin of high thermal conductivity in disentangled ultra-high molecular weight polyethylene films: ballistic phonons within enlarged crystals

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 […]

How to See Hidden Patterns in Metamaterials with Interpretable Machine Learning

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 […]

Exploiting Robust Unsupervised Video Person Re-identification

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 […]

Nonlinear noise regression in gravitational-wave detectors with convolutional neural networks

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Hang Yu, Rana X. Adhikari, , , | Summary: Currently, the sub-60 Hz sensitivity of gravitational-wave (GW) detectors like Advanced LIGO is limited by the control noises from auxiliary degrees of freedom, which nonlinearly couple to the main GW readout. One particularly promising way to tackle […]
