What is the Programmable Order by Disorder Effect in Quantum Simulators?

The programmable order by disorder effect is a phenomenon observed in quantum simulators, which are devices that use quantum mechanics to simulate complex systems. This effect is characterized by the presence of subextensive degenerate ground states in the classical limit of a system, which are composed of continuous strings with a high degree of freedom in their configuration. In this study, the researchers focused on two configurations: the stripe up and down spins aligning straightly and the kinked up and down spins forming zigzag spin chains patterns.

The researchers used real space perturbation theory to estimate the leading order energy correction when the nearest-neighbor spin exchange coupling, denoted as J, is considered. The overall model becomes an effective XXZ model with a spatial anisotropy. Their calculations demonstrated a lifting of the degeneracy, favoring the stripe configuration. When J becomes larger, the researchers adopted the infinite projected entangled-pair state (iPEPS) and numerically checked the effect of degeneracy lifting. The iPEPS results showed that even when the spin exchange coupling is strong, the stripe pattern is still favored.

The programmable order by disorder effect was studied in a quantum simulator composed of circular Rydberg atoms in a triangular optical lattice with a controllable diagonal anisotropy. This system, known as the S12 system, can be programmed in the quantum simulator. The researchers’ findings provide valuable knowledge about the quantum order by disorder effect of the S12 system.

How Can the Dipolar Bosonic Model be Realized in Quantum Simulators?

The researchers also studied the dipolar bosonic model with a tilted polar angle, which can be realized through a quantum simulator composed of cold atomic gas with dipole-dipole interaction in an optical lattice. By placing the atoms in a triangular lattice and tilting the polar angle, the diagonal anisotropy can also be realized in the bosonic system.

The researchers used cluster mean-field theory calculation to provide various phase diagrams for the bosonic system. These diagrams are useful for understanding the behavior of the system under different conditions. The researchers’ work on the dipolar bosonic model contributes to the understanding of how quantum simulators can be used to simulate complex systems.

The study of the dipolar bosonic model and the programmable order by disorder effect in quantum simulators is a significant contribution to the field of quantum physics. The researchers’ findings provide valuable insights into the behavior of quantum systems and the potential applications of quantum simulators.
