A graph-theoretic analysis of non-generic free-fermion solvability by Krylov decompositions
Jannis Ruh, Samuel J. Elman, Adrian Chapman
Exactly solvable models are often identified from structural features of their interactions. For quantum spin Hamiltonians, these are captured by the frustration graph of anticommu…

Single-Particle Spectral Estimation
Adrian Chapman, Charles Derby, Steven T. Flammia +3
We study Hamiltonian learning in a novel setting, where we are promised a physical structure that is obfuscated by a global unitary. In particular, we consider the task of learning…
