Phys.org / Mathematical 'sum of zeros' trick exposes topological magnetization in quantum materials

A new study addresses a foundational problem in the theory of driven quantum matter by extending the Středa formula to non-equilibrium regimes. It demonstrates that a superficially trivial "sum of zeros" encodes a universal, ...
