Topology plays a fundamental role in classical physics phenomena
Topology plays a fundamental role in classical physics phenomena, influencing behavior such as defect-driven energy transfer, spacetime crystal melting, and topologically protected edge oscillations in classical dynamical systems.
The retrieved papers provide robust examples of topology playing a crucial role in classical physical phenomena, ranging from classical spacetime crystals and active nematics to nonlinear classical oscillators.
Liu G, Bai J, Baggioli M, Zhang J. Three-stage melting of a macroscopic continuous spacetime crystal.. 2026. https://doi.org/10.1073/pnas.2613063123
Demonstrates that classical continuous spacetime crystals undergo a melting process where spatial order is destroyed by the proliferation of topological defects.

Shows that topological defects drive energy transfer in active nematics during defect chaos.
Nag Chowdhury S, Meyer-Ortmanns H. Topologically protected edge oscillations in nonlinear dynamical units.. 2025. https://doi.org/10.1103/lskh-hp3x
Establishes that topological characteristics and bulk-boundary correspondence explain the robust edge-localized oscillations in classical nonlinear dynamical oscillator systems.
