Spread Complexity and Topological Transitions in the Kitaev Chain
Pawel Caputa, Nitin Gupta, S. Shajidul Haque +3
A number of recent works have argued that quantum complexity, a well-known concept in computer science that has re-emerged recently in the context of the physics of black holes, ma…

Quantum complexity and topological phases of matter
Pawel Caputa, Sinong Liu
In this work, we find that the complexity of quantum many-body states, defined as a spread in the Krylov basis, may serve as a new probe that distinguishes topological phases of ma…

Entanglement Entropy and Phase Space Density: Lowest Landau Levels and 1/2 BPS states
Sumit R. Das, Shaun Hampton, Sinong Liu
We consider the entanglement entropy of an arbitrary subregion in a system of non-relativistic fermions in dimensions in Lowest Landau Level (LLL) states. Using the conne…
