Long-range electron-electron interactions in quantum dot systems and applications in quantum chemistry

Long-range interactions play a key role in several phenomena of quantum physics and chemistry. To study these phenomena, analog simulators provide an appealing alternative to classical numerical methods. Gate-defined dots have been established as platform for simulation, but those experiments the effect long-range between electrons did not crucial role. Here we present first detailed experimental characterization electron-electron array gate-defined semiconductor dots. We demonstrate significant interaction strength among that are separated by up four sites, show our theoretical prediction screening effects matches well results. Based on findings, investigate how quantum-dot arrays may be utilized simulations artificial matter. numerically about ten sufficient observe binding one-dimensional $H_2$-like molecule. These combined results pave way future with dot benchmarks methods
