Complexity of topologically frustrated systems
ORAL
Abstract
In my talk, I will present a summary of our main results about the complexity of the ground states of topologically frustrated systems. A topological frustration arises when, in a short-range antiferromagnetic system made of an odd number of spins, periodic boundary conditions are considered. We characterize the increment of the ground state complexity exploiting different approaches as the analysis of the non-stabilizerness (or "magic") and of the stochastic irreversibility of the entanglement.
