Transformer-Based Geometric Tomography of Complex-Energy Braiding Topology in a Dissipative BEC Simulator

A Transformer ML model achieves 99.93% accuracy classifying complex-energy braiding topology in dissipative BEC experiments, autonomously identifying band crossings as key geometric features—bridging non-Hermitian topology and quantum ML.

Fibonacci Quasiperiodic Lattices Suppress Non-Hermitian Skin Effect While Preserving Topological Gap

Fibonacci quasiperiodic 89-site systems reduce boundary state accumulation by >50% vs periodic lattices in 1D non-Hermitian quantum walks, maintaining a clear topological gap and enabling robust isolation of topological edge modes for quantum devices.

First Experimental Realization of 2D Floquet Non-Abelian Band Topology in Photonic Scattering Networks

Researchers built a Kagome-lattice microwave network of ferrite circulators to experimentally realize 2D Floquet non-Abelian topology, observing anomalous multi-gap phases, Euler class transfer, and antichiral edge states inaccessible in static systems.

Complete Classification of 2D Symmetry Protected Topological States with Symmetric Entanglers

Proves 2D bosonic SPT phases with symmetric entanglers are fully classified by H³(G,U(1)), resolving a longstanding open problem via group cohomology and finite-depth quantum circuit methods on infinite lattice spin systems.

Non-Hermitian Skin Effect Originates from Spectral Instability, Not Topology

NHSE in non-Hermitian systems is driven by spectral instability of non-normal operators, not point-gap topology. A Hatano-Nelson ladder demonstrates NHSE and winding are independent; true topology resides in the singular-value spectrum.

Remote Topological Control of Quantum Skyrmions to Visualise Tripartite Entanglement

First experimental visualisation of tripartite entanglement via spin-skyrmion states, demonstrating non-local topological switching, quantum multiskyrmions, and GHZ-embedded Bell state dynamics using entangled photon pairs.
