Catalytic Tomography of Ground States
Chi-Fang Chen, Robbie King
We introduce a simple protocol for measuring properties of a gapped ground state with essentially no disturbance to the state. The required Hamiltonian evolution time scales invers…

Strongly interacting fermions are non-trivial yet non-glassy
Eric R. Anschuetz, Chi-Fang Chen, Bobak T. Kiani +1
Random spin systems at low temperatures are glassy and feature computational hardness in finding low-energy states. We study the random all-to-all interacting fermionic Sachdev--Ye…
