Using large-scale molecular dynamics simulations, this study reveals that physisorbed aluminum and copper nanoparticles exhibit distinct morphological and contact mechanics scaling behaviors that deviate from thermodynamic limits below a critical size of 3–6 nm, whereas larger particles display self-affine surface roughness and approach bulk-like properties.
This study reveals that while spectral properties of diffusion-limited aggregation fractals in 2D exhibit universal localization, those in 3D display a tunable localization-to-non-ergodic transition characterized by the emergence of critical states and a hierarchy of compact localized states as the fractal dimension increases.
By combining angle-resolved photoemission spectroscopy and first-principles calculations, this study reveals that the Laves-phase superconductor CsBi2 hosts a dispersionless topological flat band and coupled type-I and type-II saddle points that collectively generate a large electron density of states, offering a novel mechanism for enhancing many-body interactions in three-dimensional systems with strong spin-orbit coupling.
This paper presents a comprehensive theory demonstrating that in non-degenerate HgTe quantum wells at charge neutrality, the electrical conductivity exhibits a temperature-driven crossover from massless Dirac-dominated transport to a regime where Coulomb scattering with thermally excited massive holes induces a negative, non-Drude correction, thereby establishing the system as a tunable platform for studying interaction-driven transport without Galilean invariance.
This study reveals that water fills nanoscale capillaries in discrete molecular layers when the walls are flexible, whereas rigid walls lead to abrupt filling, demonstrating that wall compliance governs the transition between these regimes through the competition between deformation energy and oscillatory wall-water interactions.
This paper establishes a first-frequency-moment optical Hall absorption sum rule for time-reversal-breaking systems, demonstrating that it vanishes for zero-field moiré topological bands while taking a universal value determined by magnetic flux in Hofstadter models, thereby providing a rigorous framework to link low- and high-frequency spectral contributions and diagnose Landau-level mixing.
This paper establishes an exact analytical relation showing that the time-independent areal rate of Zitterbewegung in two-dimensional Dirac systems is directly determined by the Berry curvature, thereby linking interband quantum dynamics to topological band geometry independent of the initial state.
This paper investigates how engineered dissipative and dephasing environments can activate work extraction (ergotropy) in interacting spin-chain quantum batteries, revealing that purely dissipative dynamics can induce transient Mpemba-like advantages and temperature-dependent steady states via dark subspaces, whereas dephasing channels generally suppress such extractable work.
This paper reports the synthesis and characterization of covalently linked spin-1/2 and spin-1 triangular nanographenes that form tunable heterospin systems with robust ferrimagnetic interactions, enabling the engineering of both compensated and uncompensated ground states for potential applications in qudit-based quantum technologies.
This paper introduces a new Wannier-function-based approach grounded in the modern theory of orbital magnetization to accurately quantify orbital angular momentum by capturing both local and itinerant contributions, thereby revealing significant non-local corrections to the orbital Hall conductivity that are missed by traditional atom-centered approximations.
