Topological lower bound on quantum chaos by entanglement growth
Zongping Gong, Lorenzo Piroli, J. Ignacio Cirac
A fundamental result in modern quantum chaos theory is the Maldacena-Shenker-Stanford upper bound on the growth of out-of-time-order correlators, whose infinite-temperature limit i…
Error bounds for constrained dynamics in gapped quantum systems: Rigorous results and generalizations
Zongping Gong, Nobuyuki Yoshioka, Naoyuki Shibata +1
In arXiv:2001.03419 we introduce a universal error bound for constrained unitary dynamics within a well-gapped energy band of an isolated quantum system. Here, we provide the full…
Universal Error Bound for Constrained Quantum Dynamics
Zongping Gong, Nobuyuki Yoshioka, Naoyuki Shibata +1
It is well known in quantum mechanics that a large energy gap between a Hilbert subspace of specific interest and the remainder of the spectrum can suppress transitions from the qu…
