  • Unveiling the polarization switching pathway through tetragonal phase as a metastable intermediate state in ferroelectric HfxZr1-xO2 thin film

    Unveiling the polarization switching pathway through tetragonal phase as a metastable intermediate state in ferroelectric HfxZr1-xO2 thin film

    Theoretical prediction of triple-well energy function in FE-like HZO

    We start by explaining how a triple-well energy function of FE-HZO is obtained. The evolution from AFE-like behavior to FE-like one in polarization switching cycling of HZO…

  • Single shot latched readout of a quantum dot qubit using barrier gate pulsing

    Single shot latched readout of a quantum dot qubit using barrier gate pulsing

    Figure 1 shows the device layout and the operational scheme for latched readout of a QDHQ. Figure 1a is a false-color scanning electron microscope (SEM) image of an overlapping-gate device fabricated on a Si/SiGe heterostructure similar to that…

  • Localized statistics decoding for quantum low-density parity-check codes

    Localized statistics decoding for quantum low-density parity-check codes

    The decoding problem

    In this paper, we focus on the Calderbank-Shor-Steane (CSS) subclass of QLDPC codes. These codes are defined by constant weight Pauli-X and –Z operators called checks that generate the stabilizer group defining the code space….

  • New insights into the docking mechanism of vanillin on three mammalian olfactory receptors via a new statistical physics model

    New insights into the docking mechanism of vanillin on three mammalian olfactory receptors via a new statistical physics model

    Modeling results

    A numerical computer program is employed to assess the performance of the finite multi-layer model (from L = 1 to L = 10) on the experimental concentration–response curves, i.e., the evaluation of the coherence between…

    Thermodynamics-inspired high-entropy oxide synthesis | Nature Communications

    Rock salt high-entropy oxide thermodynamics

    We begin by examining fundamental thermodynamic variables to assess rock salt HEOs stability and develop intuition into their synthesizability. In Fig. 1a, we present an enthalpic stability map (adapted…

  • Emergent Wigner phases in moiré superlattice from deep learning

    Emergent Wigner phases in moiré superlattice from deep learning

    Deep learning architecture

    Figure 1 summarizes the overall workflow. First of all, to explore the quantum phases of moiré materials, a neural network is employed to represent the many-body wavefunction. The neural network wavefunction Ψnet has…

  • Nonlocal complex short pulse equation in $${\mathcal{P}\mathcal{T}}$$ -symmetry like symmetry breaking, breather–grammian interactions and soliton solutions

    Nonlocal complex short pulse equation in $${\mathcal{P}\mathcal{T}}$$ -symmetry like symmetry breaking, breather–grammian interactions and soliton solutions

    The short pulse (SP) equation is well known equation used for describing the propagation of ultra-short optical pulses in quartz fibers by Schafer and Wayneo1,2. The SP equation is
