This study demonstrates that localized bubble corrugation in bilayer blue phosphorus creates a geometry-defined metal–semiconductor–metal homojunction capable of electromechanical switching and momentum-selective transport, enabling applications such as high-ratio memory elements and nanoscale displacement sensors without chemical doping.
This study utilizes angle-resolved vector piezoresponse force microscopy to experimentally demonstrate the existence of topologically non-trivial meron and antimeron structures in marginally twisted bilayer WSe2, successfully distinguishing between twist-induced Bloch-type and strain-induced Neel-type polar domains to establish a link between moiré engineering and real-space topology in 2D semiconductors.
This paper demonstrates that a transformer neural network architecture, leveraging its ability to capture long-range temporal correlations, outperforms traditional control methods like recurrent neural networks in quantum feedback tasks such as state stabilization and energy minimization, even under challenging conditions like inefficient measurements, Hamiltonian perturbations, and non-Markovian dynamics.
This paper proposes a minimal braiding setup in a linear quantum dot-superconductor array and demonstrates that optimal control of an ancillary quantum dot can effectively mitigate errors arising from Coulomb repulsion and residual tunneling, thereby enabling robust Majorana zero mode braiding.
This study demonstrates that in atomically thin direct gap semiconductors, resonant perturbative nonlinear optics can simultaneously induce ultrafast coherent bandgap modulation via intensity-dependent Stark and Bloch-Siegert shifts and enable non-invasive spectroscopy, thereby challenging the conventional distinction between modulation and detection regimes and redefining the limits of perturbative nonlinear optics.
Researchers synthesized and characterized a CCl molecule exhibiting half-Möbius topology with helical orbitals, demonstrating its reversible switching between chiral singlet states and a planar triplet state driven by a helical pseudo Jahn-Teller effect.
This paper proposes a multiterminal device that tunes Josephson coupling energy via supercurrent bias from separate leads, offering a flux-loop-free alternative for frequency-tunable qubits with significantly reduced susceptibility to magnetic noise.
This study reveals that extremely dilute magnetic disorder induces gapless superconductivity in 2H-NbSe2-xSx, a phenomenon driven by Se-S substitution-induced band structure modifications that alter in-gap scattering mechanisms and challenge the conventional understanding of disorder robustness in superconductors.
Using Density Functional Theory, this study reveals that interacting phosphorus and boron/aluminum -doped layers in silicon mimic intrinsic silicon at separations under 1 nm due to potential cancellation, while behaving as independent p-n junctions at larger distances with enhanced tunneling probabilities.
This paper reports the successful demonstration of stable, single-mode, continuous-wave lasing at room temperature in high-quality molecular-beam epitaxy-grown micropillar cavities with a 5 μm diameter, achieving a low threshold of 1.2 mW and a quality factor exceeding 8000.
