Interaction geometry and ground-state properties of sparse quantum lattice models
Alex Gunning, Sebastian Schmid, Zhengxiao Liu +3
We investigate how interaction geometry shapes the low-energy phases of sparse tunable long-range quantum models. We focus on a class of graphs whose degree grows logarithmically w…

Geometry-driven transitions in sparse long-range spin models with cold atoms
Alex Gunning, Aydin Deger, Sridevi Kuriyattil +1
We explore the influence of geometry in the critical behavior of sparse long-range spin models. We examine a model with interactions that can be continuously tuned to induce distin…

Efficiency of Feynman's quantum computer
Ralph Jason Costales, Alex Gunning, Tony Dorlas
Feynman's circuit-to-Hamiltonian construction enables the mapping of a quantum circuit to a time-independent Hamiltonian. This model introduces a Hilbert space made from an ancilla…
