This paper introduces projected amorphous topological insulators (PATIs), a new class of systems where a fraction of randomly selected disconnected sites from a parent crystal retains quantized global or fragile local topological invariants and boundary modes, exhibiting a tunable strong-to-fragile quantum phase transition characterized by a specific correlation length exponent.
This paper establishes that the disorder-driven Weyl semimetal-to-metal quantum phase transition possesses lower and upper critical dimensions of and , respectively, with a correlation length exponent of for and a dynamic scaling exponent of for , as confirmed by both numerical simulations and field-theoretic renormalization group calculations.
This paper demonstrates that current-induced magnon creation and annihilation significantly distort spin-orbit torque estimates in various bilayer systems, leading to substantial overestimations if unaccounted for, and proposes a reliable method to quantify and correct these effects by combining nonlinear magnetoresistance measurements.
This paper demonstrates that magnetically doped topological insulators serve as a versatile platform for realizing non-Hermitian dynamics, specifically exhibiting the non-Hermitian skin effect in the quantum anomalous Hall phase and asymmetric bidirectional coupling in the metallic phase through tunable chiral edge states.
This paper introduces an efficient real-space spectral method using Chebyshev polynomial expansions to compute orbital magnetization and bulk Chern numbers in large, disordered quantum systems without requiring explicit eigenstate calculations, offering a robust alternative to traditional k-space formulations.
This study demonstrates that a modified ligand-assisted reprecipitation (LARP) method, enhanced by amine-mediated size trimming and DDAB surface passivation, produces single CsPbBr3 perovskite quantum dots with state-of-the-art optical properties, including stable emission and high-purity single-photon generation, establishing it as a viable, milder alternative to traditional hot-injection synthesis.
This paper demonstrates that in a two-dimensional Rashba system with an in-plane Zeeman field and point-like disorder, the leading-order dc conductivity remains isotropic and field-independent due to a geometric identity ensuring the total occupied Fermi area is invariant, thereby precluding anisotropic magnetoresistance.
This paper establishes a real-space theoretical framework demonstrating that coupling -triangulenes with armchair graphene nanoribbons generates compact localized node orbitals at junctions, whose chirality and degeneracy are governed by a general counting relation between constituent end states and zero-energy modes, thereby enabling the design of artificial quantum materials with tunable flat bands and anisotropic transport.
This paper demonstrates that in two-flavor Weyl semimetals, interaction-driven matrix density waves generate a specific order-parameter manifold that supports both hedgehog point defects and Alice string line defects, enabling the fractionalization of electronic charge into and the non-trivial topological interplay between these defect types.
This study demonstrates that twisting a graphene catenoid bridge induces geometric phases and a twist potential that enhance inter-layer barriers and enable chiral-dependent electron localization, offering a mechanical method to control quantum transport in graphene-based wormhole architectures.
