Quantum correlation dynamics with large two-dimensional trapped-ion crystals
Abstract
This project aims to realize quantum simulations of two long-standing and highly sought-after problems in condensed matter physics- two-dimensional frustrated quantum spin systems and p+ip superfluids. Two-dimensional antiferromagnetic frustrated spin systems with trapped ions have so far only been realized in systems up to 10 ions. Here, we plan to increase the system size by over an order of magnitude. The proposed research could permit the investigation of a spin liquid, a hypothesized state of matter dominated by nearest-neighbor interactions and long-range quantum correlations, and with a potential impact on our understanding of high-temperature superconductivity. Our platform consists of large two-dimensional laser-cooled ion crystals in a Penning trap. In these ion crystals, the particles self-assemble in a triangular lattice, making them ideally suited to study spin frustration. Coherent laser manipulation enables us, for example, to generate an effective tunable antiferromagnetic spin-spin interaction. The study will only be possible due to our recently developed unique single-ion imaging systems, enabling us to detect the spin states of hundreds of simultaneously trapped ions with high efficiency. Based on this, we aim to advance the state-of-the-art in ion trapping by developing a single-ion addressing system for fast-rotating ion crystals in a Penning trap for the first time. Ultimately, we will employ these novel techniques and take advantage of the fast-spinning motion of the ion crystal in our trap to simulate the dynamical phases of two-dimensional p+ip superfluids for the first time.
