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 […]

Arresting Quantum Chaos Dynamically in Transmon Arrays

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 […]

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 […]

Unconventional superconductivity in twisted bilayer WSe2

Kavli Affiliate: Jie Shan | First 5 Authors: Yiyu Xia, Zhongdong Han, Kenji Watanabe, Takashi Taniguchi, Jie Shan | Summary: Moir’e materials have enabled the realization of flat electron bands and quantum phases that are driven by strong correlations associated with flat bands. Superconductivity has been observed, but solely, in graphene moir’e materials. The absence […]
