- Nature, Published online: 07 October 2026; doi:10.1038/s41586-026-11099-x Experimental evidence indicating that critical gapless topological states can be characterized by the entanglement spectrum and wavefunctions is presented, demonstrating persistence of topology at phase boundaries and…
- Nature, Published online: 07 October 2026; doi:10.1038/s41586-026-11067-5 Using an acoustic metamaterial platform, a critical topological phase transition is experimentally demonstrated establishing a hierarchical phase transition organization, in which topology shapes criticality beyond the…
