Measuring Mixed-State Topological Invariant in Photonic Quantum Walk

Published:Dec 31, 2025 13:32
1 min read
ArXiv

Analysis

This paper presents an experimental protocol to measure a mixed-state topological invariant, specifically the Uhlmann geometric phase, in a photonic quantum walk. This is significant because it extends the concept of geometric phase, which is well-established for pure states, to the less-explored realm of mixed states. The authors overcome challenges related to preparing topologically nontrivial mixed states and the incompatibility between Uhlmann parallel transport and Hamiltonian dynamics. The use of machine learning to analyze the full density matrix is also a key aspect of their approach.
Reference

“The authors report an experimentally accessible protocol for directly measuring the mixed-state topological invariant.”

Principal Eigenvalues and Behavior of Weighted p-Laplacian with Robin Conditions

Published:Dec 25, 2025 18:07
1 min read
ArXiv

Analysis

This paper addresses a gap in the spectral theory of the p-Laplacian, specifically the less-explored Robin boundary conditions on exterior domains. It provides a comprehensive analysis of the principal eigenvalue, its properties, and the behavior of the associated eigenfunction, including its dependence on the Robin parameter and its far-field and near-boundary characteristics. The work's significance lies in providing a unified understanding of how boundary effects influence the solution across the entire domain.
Reference

“The main contribution is the derivation of unified gradient estimates that connect the near-boundary and far-field regions through a characteristic length scale determined by the Robin parameter, yielding a global description of how boundary effects penetrate into the exterior domain.”
