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

Abstract: Long-range interactions play a key role in several phenomena of quantum physics and chemistry. To study these phenomena, analog quantum simulators provide an appealing alternative to classical numerical methods. Gate-defined quantum dots have been established as a platform for quantum simulation, but for those experiments the effect of long-range interactions between the electrons did not play a crucial role. Here we present the first detailed experimental characterization of long-range electron-electron inter… Show more

“…We also envision that the methods developed in Chapter 6 and 7 to engineer non-local interactions in ultra-cold atoms can be exported to explore other phenomena where such interactions play a role, like in long-range enhanced topological superconductors [378]. In this quest, we have also developed strategies to encode a non-local Hamiltonian into a discretized cold-atom simulator, as well as to mitigate finite-size effects, that can be readily exported to other platforms where long-range interactions become accessible, as it could be the case of recent experiments with semiconductor quantum dots [379].…”
