Higher-Order Krylov State Complexity in Random Matrix Quenches
Hugo A. Camargo, Yichao Fu, Viktor Jahnke +2
In quantum many-body systems, time-evolved states typically remain confined to a smaller region of the Hilbert space known as the . The time evolution can…

Spread and Spectral Complexity in Quantum Spin Chains: from Integrability to Chaos
Hugo A. Camargo, Kyoung-Bum Huh, Viktor Jahnke +3
We explore spread and spectral complexity in quantum systems that exhibit a transition from integrability to chaos, namely the mixed-field Ising model and the next-to-nearest-neigh…
