From Spin Superfluid Diode to

Correlated Quantum Sensing:

A Dissipation-Guided Blueprint

Recent advances in photonics and quantum optics have recast dissipation and gain as controllable resources, yielding a symmetry- and dynamics-guided framework for engineering new phases and functionalities. I will demonstrate how translating this framework to magnetic systems enabled us to identify novel routes to nonreciprocal spin-wave transport and to expose an emergent many-body phase, i.e., a spin-superfluid diode that promises an experimentally accessible platform for analogue-gravity experiments. I will then extend these ideas to the quantum regime,  introducing quantum‑hybrid spin architectures that realize cooperative quantum effects beyond conventional quantum‑optical platforms, and outlining sensing strategies that move past the single‑defect paradigm in solid‑state spin metrology.
