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…

Locality and filter design for dissipative ground-state preparation
Samuel J. Elman
Ground-state preparation is a fundamental challenge in quantum many-body physics, chemistry and materials science. Dissipative state-preparation techniques engineer a Lindbladian c…

Dissipative continuation for ground-state preparation at chemical transition states
Thomas W. Watts, Soumya Sarkar, Daniel Collins +4
Simulating chemical reactions exhibits a pronounced unevenness in computational difficulty: while equilibrium reactant and product geometries are often tractable, transition-state…
