Breakdown of adiabaticity in topological quantum liquids
Carola Ciaramelletti, Daniel Arrufat-Vicente, Simone Paganelli +1
We study the temporal behavior of topological quantum fluids with strong long-range couplings under slow external perturbations, whose rate approaches the quasi-static limit $…

Resource complexity of Symmetry Protected Topological phases
Alberto Giuseppe Catalano, Sven Benjamin KožiÄ, Gianpaolo Torre +4
We pursue the identification of quantum resources carried by topological order, by evaluating quantum magic, quantified through the rank- Stabilizer Rényi entropy $\mathcal{M}_…

Detecting quasi-degenerate ground states in topological models via variational quantum eigensolver
Carola Ciaramelletti, Martin Beseda, Mirko Consiglio +3
We study the exact ground states of the Su--Schrieffer--Heeger open chain and of the Kitaev open chain, using the Variational Quantum Eigensolver (VQE) algorithm. These models host…
