Interplay between local and non-local frustration in the 1D ANNNI chain I -- The even case
Gianpaolo Torre, Alberto Giuseppe Catalano, Sven Benjamin Kožić +2
We consider the effects of the competition between different sources of frustration in 1D spin chains through the analysis of the paradigmatic ANNNI model, which possesses an exten…
Magic phase transition and non-local complexity in generalized State
A. G. Catalano, J. Odavić, G. Torre +3
We employ the Stabilizer Renyi Entropy (SRE) to characterize a quantum phase transition that has so far eluded any standard description and can thus now be explained in terms of th…
Numerically efficient unitary evolution for Hamiltonians beyond nearest-neighbors
Alberto Giuseppe Catalano
Matrix product states (MPSs) and matrix product operators (MPOs) are fundamental tools in the study of quantum many-body systems, particularly in the context of tensor network meth…
