| 概 要 |
I will first briefly discuss the physics of two and three ultracold Rydberg atoms trapped by optical fields and interacting via the dipole-dipole interaction.
These systems can form micrometre sized dimer molecules whose relative dynamics is governed by artificial gauge fields and genuinely three-body bound trimer states. I will discuss how the study of these bound states leads to questions about the electronic structure of highly excited arrays of atoms in optical lattices and specifically the prospect of forming strongly correlated electron gases starting from ultracold Rydberg atoms in optical lattices. I will describe our progress in electronic structure calculations for Rydberg atoms with electrons that are delocalized over the optical lattice. I will explain how this system might form a Rydberg crystal with strongly correlated electrons, a spatial periodicity of several hundred nanometres, and coherent dynamics on experimentally resolvable picosecond time scales. I will present the exciting properties that such an electronic system might possess and discuss some of the major challenges in realizing them.
