This paper demonstrates that long-range interactions in a quantum charger can induce a collective steady-state charging mode with superextensive power that scales superlinearly with system size, a phenomenon validated through Lipkin-Meshkov-Glick and power-law spin chain models and proposed for experimental verification in trapped-ion systems.
This study utilizes kinetic Monte Carlo simulations to demonstrate that while gas-dust drift increases H-atom collision rates, the resulting higher impact energies can significantly suppress molecular hydrogen formation efficiency by reducing sticking probabilities, thereby challenging the assumption that relative motion always enhances H production in dynamically active interstellar environments.
This paper presents a unified theory of magic angles in twisted bilayer graphene within a chiral continuum model, demonstrating that the phenomenon arises from a non-Abelian pseudo-magnetic field which generates an asymptotic sequence of flat bands, distinct topological phases, and a specific scaling rule for higher-order magic angles.
This paper proposes a microscopic mechanism explaining negative charging energy in LaAlO/SrTiO quantum dots, demonstrating that the paraelectric response of SrTiO generates electrostatic image charges that induce a tunable regime of robust electron pairing.
This paper predicts that ultra-small-angle twisted graphene multilayers separated by a monolayer hBN spacer exhibit tunable minibands and van Hove singularities, leading to high-temperature, 1/B-periodic magnetotransport oscillations driven by interlayer hybridisation and Brown-Zak effects.
This study demonstrates that triblock elliptical particles with attractive patches self-assemble into tunable porous networks ranging from ordered kagome lattices to disordered structures via a unique one-step nucleation pathway, while introducing a novel particle-patch graph framework to characterize the resulting bonding motifs and pore geometries.
This paper develops a continuum variational theory for Andreev spin qubits that reveals how coherent two-quasiparticle configurations dominate spin-dependent Josephson couplings and provides closed-form expressions for key parameters, bridging strongly correlated quantum-dot models with effective circuit Hamiltonians.
This paper proposes using a quantum twisting microscope with a sublattice-polarized tip to directly measure the momentum-dependent quantum geometry and sublattice symmetries in two-dimensional flat-band systems, thereby enabling the identification of interaction-induced phases in materials like twisted bilayer graphene.
This study theoretically demonstrates that coherent control of transmission functions via quantum interference in multi-dot Aharonov-Bohm heat engines enables the engineering of hybrid spectral profiles that simultaneously optimize thermoelectric efficiency, power output, and the figure of merit , with performance scaling favorably with system size and asymmetry.
This paper solves the spin quantum Hall transition on random networks by mapping it to classical percolation and employing two-dimensional quantum gravity tools to derive exact critical exponents that confirm the validity of the KPZ relation and the relevance of geometric randomness.
