TL;DR: Two software libraries are presented: t5x simplifies the process of building and training large language models at scale while maintaining ease of use, and seqio provides a task-based API for simple creation of fast and reproducible training data and evaluation pipelines.
Journal ArticleDOI
Honeycomb Schrödinger Operators in the Strong Binding Regime
TL;DR: In this article, the Schrodinger operator for a large class of periodic potentials with the symmetry of a hexagonal tiling of the plane is studied, and it is shown that the lowest two Floquet-Bloch dispersion surfaces converge uniformly to those of the two-band tight-binding model.
Journal ArticleDOI
Topologically protected states in one-dimensional continuous systems and Dirac points.
TL;DR: This work presents a rigorous study of a class of continuum models, for which it is proved the emergence of topologically protected edge states, which are bifurcations at linear band crossings (Dirac points) of localized modes.
Journal ArticleDOI
Edge States in Honeycomb Structures
TL;DR: In this article, the existence of topologically protected edge states along zigzag edges of certain honeycomb structures has been shown for a class of Schrodinger operators with a background two-dimensional honeycomb potential perturbed by an edgepotential.
Journal ArticleDOI
Elliptic operators with honeycomb symmetry: Dirac points, Edge States and Applications to Photonic Graphene
TL;DR: In this paper, it was shown that a small and slow variations of a domain wall across a line-defect gives rise to the bifurcation from Dirac points of highly robust (topologically protected) edge states.
