DOI: 10.1002/admi.202500711

Abstract: Ru3Sn7 is experimentally demonstrated as an efficient catalyst, with potential utilization of topological surface states for hydrogen evolution reaction. Despite its promising catalytic performance, the topological nature of Ru3Sn7 remains uncertain. Particularly, the bulk‐boundary correspondence… read more here.

DOI: 10.1038/s41567-020-0836-6

Abstract: Bulk–boundary correspondence, a guiding principle in topological matter, relates robust edge states to bulk topological invariants. Its validity, however, has so far been established only in closed systems. Recent theoretical studies indicate that this principle… read more here.

DOI: 10.1103/physrevb.105.075126

Abstract: Dramatically different from the Hermitian systems, the conventional Bulk-Boundary Correspondence (BBC) is broken in the non-Hermitian systems. In this article, we use edge entanglement entropy to characterize the topological properties of non-Hermitian Su-Schrieffer-Heeger Hubbard model.… read more here.

DOI: 10.1103/physrevb.96.184516

Abstract: The bulk-boundary correspondence establishes a connection between the bulk topological index of an insulator or superconductor, and the number of topologically protected edge bands or states. For topological superconductors in two dimensions, the first Chern… read more here.

DOI: 10.1103/physrevd.111.026006

Abstract: We introduce a tensor network designed to faithfully simulate the AdS/CFT correspondence, akin to the multi-scale entanglement renormalization ansatz (MERA), following hyper-invariant tensor network. The proposed construction integrates bulk indices within the network architecture to… read more here.
