Kavli Affiliate: Wendy L. Freedman | First 5 Authors: M. M. Phillips, C. Ashall, Peter J. Brown, L. Galbany, M. A. Tucker | Summary: Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In this paper […]
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 […]

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 […]
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 […]

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Rohit Mukherjee, Haoyu Guo, Keiran Lewellen, Debanjan Chowdhury, | Summary: Ergodic quantum many-body systems evolving under unitary time dynamics typically lose memory of their initial state via information scrambling. Here we consider a paradigmatic translationally invariant many-body Hamiltonian of interacting bosons — a Josephson junction array in […]
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 […]
