This study demonstrates that graphene nanobubbles containing encapsulated noble gas atoms are multistable systems capable of adopting multiple distinct stationary states with varying numbers of concentric atomic layers, resulting in non-uniform shapes and pressures around 1 GPa that transition to a liquid state upon heating.
This paper introduces a simple, geometry-independent electric-current-assisted protocol for nucleating highly stable zero-field hopfion rings in chiral magnets and establishes a comprehensive homotopy-based framework for classifying these topological solitons alongside skyrmions and merons.
This paper investigates interacting excitons in two-dimensional systems with a moat dispersion, revealing that such band structures can drive statistical transmutation into chiral spin liquids at low densities and stabilize inhomogeneous condensates and supersolid phases at higher densities, even with purely repulsive interactions, suggesting these exotic states are experimentally accessible.
This paper demonstrates that clean two-dimensional electron hydrodynamics exhibits a unique intermediate transport regime characterized by superdiffusive relaxation with a dynamical exponent and a scale-dependent Drude weight suppression with exponent , a dual-exponent behavior arising from the slow relaxation of parity-odd Fermi surface deformations that can be experimentally probed via AC transport in narrow channels.
This paper establishes fundamental quantum limits for sensing spatiotemporally correlated noise, demonstrating that entangled sensors offer a scalable advantage over unentangled ones when detecting slowly decaying power-law spatial correlations, while revealing that non-Markovian noise spectra can fundamentally alter this entanglement advantage.
This paper demonstrates a robust method for tailoring band structures in graphene superlattices using the charge density waves of 1T-NbSe, revealing that the resulting spontaneous symmetry breaking in K-folded systems arises from a structural instability rather than electronic effects.
This study demonstrates that for the XXZ model, efficient adiabatic ground-state preparation relies primarily on spectral engineering strategies like initial Hamiltonian optimization to suppress critical level crossings, whereas counterdiabatic driving alone is ineffective unless these degeneracies are first removed.
This paper theoretically demonstrates that coupling a trans-polyacetylene chain to a metallic substrate via a local bath approximation induces a zero-temperature insulator-to-metal transition by suppressing Peierls dimerization, while also predicting the local nucleation of distinct metallic or dimerized phases in inhomogeneous environments to explain experimental observations and guide nanoelectronic device design.
This paper demonstrates that embedding a double-ended tuning fork resonator within a one-dimensional phononic crystal and utilizing electrostatic transduction enables the realization of high-quality mechanical oscillators, where the in-phase flexural mode confined within the bandgap exhibits a two-fold quality factor enhancement compared to an anchored resonator.
This study employs first-principles density functional theory to demonstrate that systematically doping graphene quantum dots with borazine rings allows for precise tuning of their electronic and optical properties, resulting in significant spectral broadening across the infrared to visible regions suitable for optoelectronic applications.
