Probing critical spin fluctuations with a composite magnetoelectric method: A case study on a Kitaev spin liquid candidate Na$_3$Co$_2$SbO$_6$

Posted by dbos June 24, 2024UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Xinrun Mi, Xintong Li, Long Zhang, Aifeng Wang, Yuan Li | Summary: In correlated quantum materials, divergent critical fluctuations near the quantum critical point are often closely associated with exotic quantum phases of matter, such as unconventional superconductivity and quantum spin liquids. Here we present a simple […]

Transgenerational transmission of post-zygotic mutations suggests symmetric contribution of first two blastomeres to human germline

Posted by dbos June 22, 2024July 9, 2024Yale

Kavli Affiliate: Flora Vaccarino | Authors: Yeongjun Jang, Livia Tomasini, Taejeong Bae, Anna Szekely, Flora M. Vaccarino and Alexej Abyzov | Summary: Little is known about the origin of germ cells in humans. We previously leveraged post-zygotic mutations to reconstruct zygote-rooted cell lineage ancestry trees in a phenotypically normal woman, termed NC0. Here, by sequencing […]

High-Efficiency Low-Noise Optomechanical Crystal Photon-Phonon Transducers

Posted by dbos June 22, 2024Caltech

Kavli Affiliate: Oskar Painter | First 5 Authors: Sameer Sonar, Utku Hatipoglu, Srujan Meesala, David Lake, Hengjiang Ren | Summary: Optomechanical crystals (OMCs) enable coherent interactions between optical photons and microwave acoustic phonons, and represent a platform for implementing quantum transduction between microwave and optical signals. Optical absorption-induced thermal noise at cryogenic (millikelvin) temperatures is […]

Functional photoacoustic noninvasive Doppler angiography in humans

Posted by dbos June 22, 2024Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yang Zhang, Joshua Olick-Gibson, Karteekeya Sastry, Lihong V. Wang, | Summary: Optical imaging of blood flow yields critical functional insights into the circulatory system, but its clinical implementation has typically been limited to shallow depths (~1 millimeter) due to light scattering in biological tissue. Here, we […]

Parity-Odd Power Spectra: Concise Statistics for Cosmological Parity Violation

Posted by dbos June 21, 2024Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Drew Jamieson, Angelo Caravano, Jiamin Hou, Zachary Slepian, Eiichiro Komatsu | Summary: We introduce the Parity-Odd Power (POP) spectra, a novel set of observables for probing parity violation in cosmological $N$-point statistics. POP spectra are derived from composite fields obtained by applying nonlinear transformations, involving also gradients, […]

Early Galaxies and Early Dark Energy: A Unified Solution to the Hubble Tension and Puzzles of Massive Bright Galaxies revealed by JWST

Posted by dbos June 21, 2024MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Michael Boylan-Kolchin, Sandro Tacchella, Rohan P. Naidu | Summary: JWST has revealed a large population of ultra-violet (UV)-bright galaxies at $zgtrsim 10$ and possibly overly massive galaxies at $zgtrsim 7$, challenging standard galaxy formation models in the $Lambda$CDM cosmology. We use an empirical […]

FlowBench: Revisiting and Benchmarking Workflow-Guided Planning for LLM-based Agents

Posted by dbos June 21, 2024July 9, 2024Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ruixuan Xiao, Wentao Ma, Ke Wang, Yuchuan Wu, Junbo Zhao | Summary: LLM-based agents have emerged as promising tools, which are crafted to fulfill complex tasks by iterative planning and action. However, these agents are susceptible to undesired planning hallucinations when lacking specific knowledge for expertise-intensive tasks. […]
