Quantum Complexity Dynamics for Disjoint Subsystems
Yale Fan, Nicholas Hunter-Jones, Andreas Karch +2
Quantum complexity has emerged as a natural probe of chaos, thermalization, and the black hole interior on timescales long after local observables have equilibrated. However, its t…

Sharp Transitions for Subsystem Complexity
Yale Fan, Nicholas Hunter-Jones, Andreas Karch +1
The circuit complexity of time-evolved pure quantum states grows linearly in time for an exponentially long time. This behavior has been proven in certain models, is conjectured to…

Deterministic quantum trajectory via imaginary time evolution
Shivan Mittal, Bin Yan
Stochastic quantum trajectories, such as pure state evolutions under unitary dynamics and random measurements, offer a crucial ensemble description of many-body open system dynamic…
