Research Summary

Ning Su develops numerical and analytic bootstrap methods for strongly coupled quantum field theories. His recent work combines high-precision studies of the 3d Ising and N=1 super-Ising models with algorithmic advances such as navigator and hybrid bootstrap methods, extending bootstrap technology beyond isolated benchmark models. Applications to non-Abelian currents, deconfined quantum tricriticality, Potts and cubic CFTs, O(3)-to-cubic flows, and large-charge sectors all reflect the same goal: to make nonperturbative constraints sharp enough to map the landscape of strongly coupled critical theories.
