Interactionscontrol and drive the collective dynamics and emergence of correlations andpatterns in many-body systems. Dissipative (i.e. non-conservative) interactionsare especially interesting as they give rise to exotic non-equilibrium dynamicsand generate novel topological phases. Moreover, they are a key ingredient toengineer non-reciprocal interactions, which have many applications for quantumsensing.
In my talk,I will introduce a novel many-body quantum system: a trap array ofnanoparticles that interact via highly tunable light-induced dipole-dipoleforces. I will show how we realize quantum control over the motion of a singleparticle and program arbitrary non-Hermitian dynamics in a particle array.Finally, I will present recent measurements of a driven-dissipative phasetransition that stems from the non-reciprocal interaction, which demonstratesthe potential of this system to explore complex non-equilibrium phenomena.
