Excitons in Large Disordered Boron-Nitride Layer using Linear-Scaling Bethe-Salpeter Simulations
Summary
arXiv:2606.30585v1 Announce Type: new Abstract: We introduce a real-space, linear-scaling Bethe-Salpeter framework that enables excitonic spectroscopy in large and possibly disordered boron-nitride-derived systems. Thanks to the use of a sublattice-resolved perturbative decoupling that maps localized electron-hole pairs onto a sparse tight-binding model, we implement the Kernel Polynomial Method to compute absorption spectra with O(N) cost. To illustrate the capabilities of our method, we apply it to Anderson-disordered monolayer hexagonal boron nitride with up to $10^{5}$ orbitals.
Why It Matters
This Aerospace & Defense development expands Asia's independent launch, orbital and defense-technology capabilities. For Taiwan, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
