    Abstract

    We, the QUARTET Collaboration, propose an experiment to measure the nuclear charge radii of light elements with up to 20 times higher accuracy. These are essential both for understanding nuclear physics at low energies, and for experimental and theoretical applications in simple atomic systems. Such comparisons advance the understanding of bound-state quantum electrodynamics

    CP-AFM Molecular Tunnel Junctions with Alkyl Backbones Anchored Using Alkynyl and Thiol Groups: Microscopically Different Despite Phenomenological Similarity

    Yuhong Chen, Ioan Bâldea, Yongxin Yu, Zining Liang, Ming-De Li, Elad Koren, Zuoti Xie
    Abstract

    In this paper, we report results on the electronic structure and transport properties of molecular junctions fabricated via conducting probe atomic force microscopy (CP-AFM) using self-assembled monolayers (SAMs) of n-alkyl chains anchored with acetylene groups (CnA; n = 8, 9, 10, and 12) on Ag, Au, and Pt electrodes. We found that the current–voltage (IV) characteristics

    Reconciling differential radii in the silver chain through improved measurement and {\it ab initio} calculations

    Ben Ohayon, J Eduardo Padilla-Castillo, Sid C Wright, Gerard Meijer, B K Sahoo
    Abstract

    Nuclear charge radius differences in the silver isotopic chain have been reported through different combinations of experiment and theory, and clear disagreement is observed beyond the assigned uncertainties. This study investigates this issue by combining high-accuracy calculations for six low-lying states of atomic silver with an improved measurement of the $5s

    Constraining CP violating nucleon-nucleon long range interactions in diatomic eEDM searches

    Chaja Baruch, P Bryan Changala, Yuval Shagam, Yotam Soreq
    Abstract

    The searches for CP violating effects in diatomic molecules, such as $\text{HfF}^+$ and ThO, are typically interpreted as a probe of the electron's electric dipole moment ($e\text{EDM}$), a new electron-nucleon interaction, and a new electron-electron interaction. However, in the case of a non-vanishing nuclear spin, a new CP violating nucleon-nucleon long range force

    Hunting muonic forces at emulsion detectors

    Abstract

    Only two types of Standard Model particles are able to propagate the 480meters separating the ATLAS interaction point and FASER: neutrinos and muons. Furthermore, muons are copiously produced in proton collisions. We propose to use FASER ν as a muon fixed target experiment in order to search for new bosonic degrees of freedom coupled predominantly

    A blockBP decoder for the surface code

    Aviad Kaufmann, Itai Arad
    Abstract

    We present a new decoder for the surface code, which combines the accuracy of the tensor-network decoders with the efficiency and parallelism of the belief-propagation algorithm. Our main idea is to replace the expensive tensor-network contraction step in the tensor-network decoders with the blockBP algorithm - a recent approximate contraction algorithm, based on belief

    Bidirectionally injection-locked coupled microring GaN lasers

    Shinji Tohi, Gal Harari, Takumi Ito, Yaakov Lumer, Miguel A Bandres, Kunimichi Omae, Mordechai Segev
    Abstract

    Coherent high-quality laser sources are important for a variety of photonic devices and applications, yet they are especially challenging for high-power semiconductor lasers, because high-power and single-mode lasing present conflicting requirements; high power drives nonlinear processes causing multimode lasing and instabilities. Here, we present a distributed feedback

    Motion of charged particles in bright squeezed vacuum

    Abstract

    The motion of laser-driven electrons quivers with an average energy termed pondermotive energy. We explore electron dynamics driven by bright squeezed vacuum (BSV), finding that BSV induces width oscillations, akin to electron quivering in laser light, with an equivalent ponderomotive energy. We identify closed and open trajectories of the electronic width that are

    Universal transport in periodically driven systems without long-lived quasiparticles

    Iliya Esin, Clemens Kuhlenkamp, Gil Refael, Erez Berg, Mark S Rudner, Netanel H Lindner
    Abstract

    An intriguing regime of universal charge transport at high entropy density has been proposed for periodically driven interacting one-dimensional systems with Bloch bands separated by a large single-particle band gap. For weak interactions, a simple picture based on well-defined Floquet quasiparticles suggests that the system should host a quasisteady state current that

    Free-electron crystals for enhanced X-ray radiation

    Lee Wei Wesley Wong, Xihang Shi, Aviv Karnieli, Jeremy Lim, Suraj Kumar, Sergio Carbajo, Ido Kaminer, Liang Jie Wong
    Abstract

    Bremsstrahlung—the spontaneous emission of broadband radiation from free electrons that are deflected by atomic nuclei—contributes to the majority of X-rays emitted from X-ray tubes and used in applications ranging from medical imaging to semiconductor chip inspection. Here, we show that the bremsstrahlung intensity can be enhanced significantly—by more than three orders
