Neutrino follow-up with the Zwicky Transient Facility: Results from the first 24 campaigns

Posted by klaurent March 31, 2022April 11, 2022Peking

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Robert Stein, Simeon Reusch, Anna Franckowiak, Marek Kowalski, Jannis Necker | Summary: The Zwicky Transient Transient Facility (ZTF) performs a systematic neutrino follow-up program, searching for optical counterparts to high-energy neutrinos with dedicated Target-of-Opportunity (ToO) observations. Since first light in March 2018, ZTF has taken prompt […]

Dynamic scaling properties of multistep polarization response in ferroelectrics

Posted by klaurent March 31, 2022Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yuri A. Genenko, Sergey Zhukov, Maohua Zhang, Ke Wang, Jurij Koruza | Summary: Ferroelectrics are multifunctional smart materials finding applications in sensor technology, micromechanical actuation, digital information storage etc. Their most fundamental property is the ability of polarization switching under applied electric field. In particular, understanding of […]

Data Sampling Affects the Complexity of Online SGD over Dependent Data

Posted by klaurent March 31, 2022April 11, 2022UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Shaocong Ma, Ziyi Chen, Yi Zhou, Kaiyi Ji, Yingbin Liang | Summary: Conventional machine learning applications typically assume that data samples are independently and identically distributed (i.i.d.). However, practical scenarios often involve a data-generating process that produces highly dependent data samples, which are known to heavily bias […]

Mode-walk-off interferometry for position-resolved optical fiber sensing

Posted by March 31, 2022Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Simultaneously sensing and resolving the position of measurands along an optical fiber enables numerous opportunities, especially for application in environments where massive sensor deployment is not feasible. Despite significant progress in techniques based on round-trip time-of-flight measurements, the […]

Distributed optical fiber sensing using forward propagation of multiple modes

Posted by klaurent March 31, 2022April 11, 2022Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Fiber optic distributed sensors typically demand bidirectional propagation in optical fibers to localize each point of measurement. This imposes barriers to their deployment in long-haul, amplified telecommunication links and prevents massive range enhancement through in-line amplification, due to […]

Large-gap insulating dimer ground state in monolayer IrTe2

Posted by klaurent March 31, 2022April 11, 2022Berkeley

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Jinwoong Hwang, Kyoo Kim, Canxun Zhang, Tiancong Zhu, Charlotte Herbig | Summary: Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of the interlayer coupling. In this work, we […]

Chip-Based Laser with 1 Hertz Integrated Linewidth

Posted by klaurent March 31, 2022April 11, 2022Caltech

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Joel Guo, Charles A. McLemore, Chao Xiang, Dahyeon Lee, Lue Wu | Summary: Lasers with hertz-level linewidths on timescales up to seconds are critical for precision metrology, timekeeping, and manipulation of quantum systems. Such frequency stability typically relies on bulk-optic lasers and reference cavities, where increased […]

Symmetries of the Primordial Sky

Posted by klaurent March 31, 2022April 11, 2022Chicago

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: Quantum field theory, which is generally used to describe the origin of large-scale gravitational perturbations during cosmic inflation, has been shown to omit an important physical effect in curved space-time, the nonlocal entanglement among quantized modes from their gravitational effect […]
