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, 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 […]

In contrast, we explore whether some language model representations may be […]
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 […]
