$nπ$ phase ambiguity of cosmic birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Fumihiro Naokawa, Toshiya Namikawa, Kai Murai, Ippei Obata, Kohei Kamada | Summary: We point out that the rotation angle $beta$ of cosmic birefringence, which is a recently reported parity-violating signal in the cosmic microwave background (CMB), has a phase ambiguity of $npi ,(ninmathbb{Z})$. This ambiguity has a […]

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 […]

Not All Language Model Features Are Linear

Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, Isaac Liao, Eric J. Michaud, Wes Gurnee, Max Tegmark | Summary: Recent work has proposed the linear representation hypothesis: 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 […]

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 […]
