To realize the full promise of topological mechanical vibrations, they have to be controlled successfully at the nanoscale. Here the authors report topological phonon transport in an optomechanical array. This unlocks the full toolbox of cavity optom

Efficient approaches to quantum control and feedback are essential for quantum technologies, from sensing to quantum computation. Open-loop control tasks have been successfully solved using optimization techniques, including methods such as gradient-

The design of periodic nanostructures allows to tailor the transport of photons, phonons, and matter waves for specific applications. Recent years have seen a further expansion of this field by engineering topological properties. However, what is mis

Most known topological states of light are in the end closely analogous to fermionic states. Here, the authors show that the squeezing of light can lead to the formation of photonic topological states which do not have any fermionic counterpart yet s

Synchronization of weakly coupled nonlinear oscillators is a ubiquitous phenomenon that has been observed across the natural sciences. We study the dynamics of optomechanical arrays—networks of mechanically compliant structures that interact with t

We propose a novel hybrid platform where solid-state spin qubits are coupled to the acoustic modes of a two-dimensional array of optomechanical (OM) nano cavities. Previous studies of coupled OM cavities have shown that in the presence of strong opti

Optomechanical (OMA) arrays are a promising future platform for studies of transport, many-body dynamics, quantum control and topological effects in systems of coupled photon and phonon modes. We introduce disordered OMA arrays, focusing on features

Topology has appeared in different physical contexts. The most prominent application is topologically protected edge transport in condensed matter physics. The Chern number, the topological invariant of gapped Bloch Hamiltonians, is an important quan

It is now well established that photonic systems can exhibit topological energy bands. Similar to their electronic counterparts, this leads to the formation of chiral edge modes which can be used to transmit light in a manner that is protected agains

We use a modulated oscillator to study quantum fluctuations far from thermal equilibrium. A simple but important nonequilibrium effect that we discuss first is quantum heating, where quantum fluctuations lead to a finite-width distribution of a reson
