Holography for bulk-boundary local topological order
In our previous article [arXiv:2307.12552], we introduced local topological order (LTO) axioms for quantum spin systems which allowed us to define a physical boundary manifested by a net of boundary algebras in one dimension lower. This gives a formal setting for topological holography, where the braided tensor category of DHR bimodules of the physical boundary algebra captures the bulk topological order. In this article, we extend the LTO axioms to quantum spin systems equipped with a topolo…

Finding the Cores of Higher Graphs Using Geometric and Topological Means: A Survey
In this survey, we explore recent literature on finding the cores of higher graphs using geometric and topological means. We study graphs, hypergraphs, and simplicial complexes, all of which are models of higher graphs. We study the notion of a core, which is a minimalist representation of a higher graph that retains its geometric or topological information. We focus on geometric and topological methods based on discrete curvatures, effective resistance, and persistent homology. We aim to conne…

Synergy of Rashba and Topological Effects for High-Performance Bismuth-Based Thermoelectrics
Band convergence is a key strategy for enhancing thermoelectric (TE) performance. Herein, we demonstrate a promising approach to enhance band convergence through inducing Rashba splitting in topological insulators. Theoretically designed Janus $β$-Bi$_2$Se$_2$Te and $β$-Bi$_2$Te$_2$Se exhibited inherent topological band inversion and Rashba splitting due to the strong spin-orbit coupling (SOC) with broken inversion symmetry. These characteristics synergistically improve band convergence, lead…

Topological Entropy of Stationary Turbulent Flows
Topological entropy serves as a viable candidate for quantifying mixing and complexity of a highly chaotic system. Particularly in turbulence, this is determined as the exponential stretching rate of a fluid material line that typically necessitates a Lagrangian description. We extend the recent work [A. Manoharan, S. Subramanian, and A. Joy, arXiv:2412.08996] to three dimensions, and present an exact Eulerian framework for the topological entropy in stationary turbulent flows that is devoid of…

Rabi transport and the other finite-size effects in one-dimensional discrete-time topological quantum walk
This paper investigates Rabi transport and finite-size effects in one-dimensional discrete-time topological quantum walks. We demonstrate the emergence of localized states at boundaries between topologically distinct phases and analyze how finite system sizes influence quantum walk dynamics. For finite lattices, we show that topology induces localized and bilocalized states, leading to Rabi-like transport as a result of degeneracy breaking due to finite-size effects. The study bridges the gap b…

Network Structures as an Attack Surface: Topology-Based Privacy Leakage in Federated Learning
Federated learning systems increasingly rely on diverse network topologies to address scalability and organizational constraints. While existing privacy research focuses on gradient-based attacks, the privacy implications of network topology knowledge remain critically understudied. We conduct the first comprehensive analysis of topology-based privacy leakage across realistic adversarial knowledge scenarios, demonstrating that adversaries with varying degrees of structural knowledge can infer s…

Quantized and nonquantized Hall response in topological Hatsugai-Kohmoto systems
We explore the robustness of Hall conductivity quantization in several insulating systems, exhibiting one scenario where the quantization is not preserved. Specifically, we apply the Kubo formula to topological models with the Hatsugai-Kohmoto interaction. Starting from the many-body degeneracy induced by this interaction in the topological Kane-Mele model, we consider Zeeman fields to select specific states within the ground-state manifold that reveal a non-quantized Hall response, precisely f…

Spin-orbit interaction, band topology, and spin texture in BiInO3(001) surface
This research investigates the implication of spin-orbit interaction (SOI) and symmetry on the band topology and spin texture at the (001) surface of BiInO$_3$. Using density functional theory (DFT) and symmetry analysis, the study explores the impact of surface termination on the electronic structure, particularly focusing on how the loss of translational symmetry at the surface influences the band topology of the surface states. Key findings include discovering two dangling surface states (na…
