Krylov Complexity
Krylov complexity provides a powerful framework for understanding how operators and states spread across the Hilbert space of quantum systems. By studying the growth of operators in Krylov space, we gain insights into fundamental aspects of quantum chaos, thermalization, and the emergence of computational complexity in quantum many-body systems.
Our research investigates how Krylov complexity connects to holographic descriptions of quantum gravity, black hole physics, and the fundamental limits of quantum computation.
