However, understanding how these exotic degrees of freedom reconfine into new phases of matter remains a fundamental challenge. In this work, we demonstrate that Polyakov\u2019s confinement mechanism-a foundation of compact gauge theory-can serve as a dynamical engine to transform a Dirac spin liquid (DSL) into a symmetry-protected topological (SPT) state. Starting with a DSL with spin-dependent gauge fluxes, we show that the single-occupancy constraint inherent to the physical Hilbert space triggers monopole condensation, dynamically confining bulk spinons while preserving gapless edge modes-realizing a spinon analog of the quantum spin Hall effect. Using a large-scale variational Monte Carlo simulation on a triangular antiferromagnet with an additional Dzyaloshinskii\u2013Moriya interaction, we provide microscopic evidence for this confined SPT phase, including a characteristic area law for the Wilson loop and vanishing topological entanglement entropy. Furthermore, we identify a measurable spin-pump response under magnetic fields, which directly encodes the Berry curvature of the parent Dirac cones. Our results reveal a previously unexplored pathway to SPT physics, bridging the fields of gauge theory, quantum magnetism, and topological matter.<\/jats:p>","DOI":"10.1088\/1361-6633\/ae921b","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T22:51:22Z","timestamp":1785365482000},"page":"080503","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Emergent symmetry-protected topological phases via Polyakov confinement in quantum spin systems"],"prefix":"10.1088","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9897-545X","authenticated-orcid":true,"given":"Li-Wei","family":"He","sequence":"first","affiliation":[{"name":"National Laboratory of Solid State Microstructures and Department of Physics, Nanjing University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7202-4851","authenticated-orcid":true,"given":"Shun-Li","family":"Yu","sequence":"additional","affiliation":[{"name":"National Laboratory of Solid State Microstructures and Department of Physics, Nanjing University"},{"name":"Collaborative Innovation Center of Advanced Microstructures, Nanjing University"},{"name":"Jiangsu Key Laboratory of Quantum Information Science and Technology, Nanjing University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3901-8119","authenticated-orcid":true,"given":"Jian-Xin","family":"Li","sequence":"additional","affiliation":[{"name":"National Laboratory of Solid State Microstructures and Department of Physics, Nanjing University"},{"name":"Collaborative Innovation Center of Advanced Microstructures, Nanjing University"},{"name":"Jiangsu Key Laboratory of Quantum Information Science and Technology, Nanjing University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"ropae921bbib1","doi-asserted-by":"publisher","first-page":"153","DOI":"10.1016\/0025-5408(73)90167-0","type":"journal-article","volume":"8","author":"Anderson","year":"1973","journal-title":"Mater.
