Numerical simulations using a coarse-grained model demonstrate that van der Waals encapsulation with a hexagonal boron nitride sheet significantly enhances the thermal stability of hydrogen-bonded chains formed by phenol derivatives, enabling their potential use as high-temperature anhydrous proton-exchange membranes.
This paper demonstrates that flux-mismatched Hofstadter bilayers enable electrically programmable topological transitions and chiral transport by leveraging topologically enforced band crossings and synthetic Weyl points to transfer Chern numbers between layers despite interlayer hybridization.
This study demonstrates that engineering a tilted uniaxial magnetic anisotropy in a Tb/Co multilayer via a thickness gradient enables precise in-plane magnetic field control over the sign and magnitude of the out-of-plane anomalous Hall response, offering a new pathway for spintronic sensor applications.
Using time-dependent density functional theory, this study reveals that low-density two-dimensional electron gases exhibit new collective excitonic modes beyond traditional plasmons, which manifest as distinct experimental signatures like asymmetric loss function peaks and strong Friedel-like oscillations, ultimately signaling an instability toward a charge-density-wave phase.
By irradiating freestanding monolayer hBN with ultra-low-energy Ar+ ions, this study reveals that boron single vacancies are the predominant defect formed contrary to simulation predictions, while impurity-driven vacancy filling plays a more significant role than previously assumed, complicating the selective engineering of quantum emitters.
This paper establishes a quantitative link between steady-state non-equilibrium Green's function (NEGF) transmission and time-domain wave packet dynamics by demonstrating that the latter represents a spectral average of the former, a correspondence that enables the direct calculation of current-voltage characteristics and spin-resolved transport through the construction of tailored non-Gaussian auxiliary wave packets.
This paper investigates the thermoelectric and thermodynamic properties of a Tomonaga-Luttinger liquid with interaction constant and a localized impurity, deriving exact expressions for thermopower and demonstrating a close connection between transport coefficients and entropy or heat capacity densities in the low-temperature regime.
This study identifies MnTe2 as a model cubic noncollinear altermagnet by demonstrating a large piezomagnetic response through combined dilatometry and nuclear magnetic resonance measurements, which reveal a linear coupling between lattice strain and magnetic moment consistent with theoretical predictions.
This review presents a unified two-step method of symmetry breaking and restoration to describe universal strongly correlated phenomena, such as electron crystallization and rotating molecules, across diverse finite systems including quantum dots, ultracold Bose gases, and traditional nuclear and chemical fields.
This paper demonstrates that two-dimensional Floquet topological phases exhibit unexpected robustness against timing noise, characterized by a distinct two-stage decay of edge modes involving initial thermalization followed by slow algebraic decay driven by one-dimensional diffusion, thereby confirming their viability for experimental applications despite unavoidable disorder and decoherence.
