The generalized 4-connectivity of godan graphs

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jiang Wu, Yuanqiu Huang, Zhangdong Ouyang, | Summary: The generalized $k$-connectivity of a graph $G$, denoted by $kappa_k(G)$, is the minimum number of internally edge disjoint $S$-trees for any $Ssubseteq V(G)$ and $|S|=k$. The generalized $k$-connectivity is a natural extension of the classical connectivity and […]

Diffuse Boosted Cosmic Neutrino Background

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Gonzalo Herrera, Shunsaku Horiuchi, Xiaolin Qi, , | Summary: Energetic cosmic rays scatter off the cosmic neutrino background throughout the history of the Universe, yielding a diffuse flux of cosmic relic neutrinos boosted to high energies. We calculate this flux under different assumptions of the cosmic-ray flux […]

The Supersonic Project: Early Star Formation with the Streaming Velocity

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William Lake, Claire E. Williams, Smadar Naoz, Federico Marinacci, Blakesley Burkhart | Summary: At high redshifts ($zgtrsim12$), the relative velocity between baryons and dark matter (the so-called streaming velocity) significantly affects star formation in low-mass objects. Streaming substantially reduces the abundance of low-mass gas objects while simultaneously […]

Interaction-induced strong zero modes in short quantum dot chains with time-reversal symmetry

Kavli Affiliate: Michael Wimmer | First 5 Authors: A. Mert Bozkurt, Sebastian Miles, Sebastiaan L. D. ten Haaf, Chun-Xiao Liu, Fabian Hassler | Summary: We theoretically explore the emergence of strong zero modes in a two-site chain consisting of two quantum dots coupled due to a central dot that mediates electron hopping and singlet superconducting […]

Not All Language Model Features Are Linear

Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, Eric J. Michaud, Isaac Liao, Wes Gurnee, Max Tegmark | Summary: Recent work has proposed that language models perform computation by manipulating one-dimensional representations of concepts ("features") in activation space. In contrast, we explore whether some language model representations may be inherently multi-dimensional. We begin […]

Quadrupolar resonance spectroscopy of individual nuclei using a room-temperature quantum sensor

Kavli Affiliate: Tim H. Taminiau | First 5 Authors: S. Alex Breitweiser, Mathieu Ouellet, Tzu-Yung Huang, Tim H. Taminiau, Lee C. Bassett | Summary: Nuclear quadrupolar resonance (NQR) spectroscopy reveals chemical bonding patterns in materials and molecules through the unique coupling between nuclear spins and local fields. However, traditional NQR techniques require macroscopic ensembles of […]

Mamba-R: Vision Mamba ALSO Needs Registers

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Jiahao Wang, Sucheng Ren, Guoyizhe Wei, Jieru Mei | Summary: Similar to Vision Transformers, this paper identifies artifacts also present within the feature maps of Vision Mamba. These artifacts, corresponding to high-norm tokens emerging in low-information background areas of images, appear much more severe in […]
