This paper demonstrates a quantum simulator using a driven Kerr parametric oscillator to create a tunable asymmetric double-well potential, revealing counter-intuitive effects where weak asymmetry suppresses activation rates and resonance widths oscillate with well parameters, thereby paving the way for analog simulations of chemical reactions like proton transfer.
This paper demonstrates that direct-write printing of conductive inks is a fast, clean, and effective alternative to traditional lithography for creating high-quality electrical contacts on various layered and 2D materials, enabling rapid prototyping and characterization without compromising material integrity.
This paper develops a semiclassical theory for electrons in non-Hermitian periodic systems to derive the orbital magnetization energy and define a generalized angular momentum operator that links the real and imaginary parts of the magnetic moment to a non-Hermitian Aharonov-Bohm effect.
Through extensive computational investigations, this study identifies new thermodynamically stable carbon defect configurations in MoS2 and refutes recent claims that these impurities cause electrical doping, demonstrating instead that they act as deep carrier traps.
This paper reviews the critical role of Rashba spin-orbit coupling in engineering low-dimensional topological superconductors that host Majorana zero modes, thereby enabling fault-tolerant topological quantum computation by enhancing the topological energy gap and protecting qubits from decoherence.
This paper theoretically investigates the nonlinear Hall effect in two-dimensional topological Dirac semimetals under an in-plane magnetic field by solving the quantum kinetic equation for the Wigner distribution function and proposes experimental verification through anomalous Hall resistivity measurements in specific materials like SnTe, WTe, WSe, and CeBiPd.
This paper introduces the concept of Wilson-loop-ideal bands, which saturate the quantum metric lower bound set by Wilson-loop windings, and proposes a general framework to construct such ideal states from non-ideal bands, enabling the creation of novel topological wavefunctions and the study of correlated physics in realistic moiré materials.
This paper reveals that while the van der Waals gap in two-dimensional materials suppresses gate leakage, it critically limits device scaling by increasing contact resistance and introducing parasitic capacitance, suggesting that "zipper-like" quasi-covalent interfaces are necessary to overcome these barriers.
This paper demonstrates that parallel metal gates placed above a two-dimensional electron system create a plasmonic cavity with unconventional mode quantization, where the lowest resonance occurs at a slot width of one-eighth the plasmon wavelength due to a unique phase shift upon reflection from the gate edge.
This paper demonstrates that spacetime curvature in and black hole backgrounds induces an effective magnetic field and chiral chemical potential for Dirac fermions, driving asymmetric real-time transport and entanglement dynamics confined within inhomogeneous Lieb-Robinson cones that are diagnostic of curvature and horizon effects.
