A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora ReiniÄ, 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…

Quantum Coherence of Topologically Frustrated Spin Chains
S. B. KožiÄ, G. Torre, K. DeliÄ +2
The study of entanglement and magic properties in topologically frustrated systems suggests that, in the thermodynamic limit, these quantities decompose into two distinct contribut…

Simulating the Fermi-Hubbard model with long-range hopping on a quantum computer
Tatiana A. Bespalova, Karlo DeliÄ, Guido Pupillo +2
We investigate the performance and accuracy of digital quantum algorithms for the study of static and dynamic properties of the fermionic Hubbard model at half-filling with next-ne…
