Non-equilibrium optically levitated interacting nanoparticle arrays

Objetivo

We propose the exploration of many-body quantum physics with a new experimental platform, based on the
optically levitated and cooled arrays of spherical nanoparticles with strong and controllable interactions. The
recent works by the host institution demonstrated the cavity assisted cooling of a single nanoparticle to its
motional quantum ground state as well as the simultaneous trapping of two nanoparticles with full control
over the interactions between them. In this work we shall extend these results to the multiple particles. This
will be on the one hand an important milestone towards achieving the many-body regime and on the other
hand, the first observation of the cavity assisted cooling of an array of nanoparticles via coherent light
scattering. The realisation of this milestone will enable us to study the system’s non-equilibrium relaxation after
precise perturbation protocols. Using the natural isolation from the environment, we shall study the
thermalisation of a nearly isolated few-particle quantum system. Depending on the energetic landscape, as well
as on the nature and range of interactions, we expect to observe motional pre-thermalisation, or the absence
of thermalisation with the onset of the Anderson localisation or the Many-Body Localisation of phonons. Finally,
we shall explore the controllable non-reciprocity of the inter-particle interactions by breaking the directional
symmetry of the inter-particle forces by conferring to them the direction dependent phases. Combining this
with the dissipative nature of these forces, we aim at implementing a specifically tailored non-hermitian
Hamiltonian describing the constant intensity waves.
