Topological frustration and quantum resources
Alberto Giuseppe Catalano, Gianpaolo Torre, Salvatore Marco Giampaolo +1
Although in general boundary conditions do not affect the bulk properties of a system, some of them are special and defy such expectation. This is the case, for instance, of those…
Resource complexity of Symmetry Protected Topological phases
Alberto Giuseppe Catalano, Sven Benjamin Kožić, 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}_2…
Experimental preparation of states through frustration on a programmable quantum simulator
Alberto Giuseppe Catalano, Ceren Dağ, Gianpaolo Torre +2
states are a central class of multipartite entangled states with applications in quantum information processing, yet their scalable and deterministic preparation remains challe…
A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora Reinić, Gianpaolo Torre +5
Topological frustration arises when boundary conditions impose geometric frustration in a quantum system, creating delocalized defects in the ground states and profoundly altering…
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…
Towards a phase diagram of the topologically frustrated XY chain
Daniel Sacco Shaikh, Alberto Giuseppe Catalano, Fabio Cavaliere +3
Landau theory's implicit assumption that microscopic details cannot affect the system's phases has been challenged only recently in systems such as antiferromagnetic quantum spin c…
Frustrating quantum batteries
Alberto Giuseppe Catalano, Salvatore Marco Giampaolo, Oliver Morsch +2
We propose to use a quantum spin chain as a device to store and release energy coherently (namely, a quantum battery) and we investigate the interplay between its internal correlat…
Anomalous diffusion in the Long-Range Haken-Strobl-Reineker model
Alberto Giuseppe Catalano, Francesco Mattiotti, Jérôme Dubail +4
We analyze the propagation of excitons in a -dimensional lattice with power-law hopping in the presence of dephasing, described by a generalized Haken-Strobl-Rei…
Simulating continuous symmetry models with discrete ones
Alberto Giuseppe Catalano, Daria Brtan, Fabio Franchini +1
Especially in one dimension, models with discrete and continuous symmetries display different physical properties, starting from the existence of long-range order. In this work, we…
