This behavior can be interpreted in terms of particles that behave like neither fermions nor bosons but like so-called anyons. Most importantly, when initializing the system with two excitations, no chiral motion is observed, showing that the gauge field generated by this mechanism actually depends on the presence of another excitation. In a minimal setting of three atoms, we observe the effect of this field by the motion of a single excitation in a preferred direction (i.e., “chiral motion”). ![]() Density Dependent Limiting Factors Density dependent limiting factors cause the per capita (per individual) growth rate of a population to change as the population gets larger. Our approach uses a novel mechanism, relying on the spin-orbit coupling intrinsic to dipolar interactions that appears in Rydberg atoms and creates an artificial magnetic field. Density dependent limiting factors are related to living organisms while density-independent limiting factors are related to the environment. Some examples of density dependent factors that. Here, we report the experimental realization of an artificial gauge field in Rydberg arrays. Density dependent factors are environmental factors that limit the population when it reaches a certain density. Therefore, finding a way to engineer gauge fields in this platform is crucial to extend the range of quantum simulations it can perform. Contrary to other approaches, these systems reach the strongly correlated regime relatively easily. Recently, arrays of interacting Rydberg atoms (atoms with one or more highly excited electrons) have become a promising quantum simulation platform. This requires creating, in systems of interacting quantum particles, artificial gauge fields, such as a typical magnetic field. The realization of artificial topological matter where interactions play a crucial role is an active topic in quantum simulation. ![]()
