Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

Levitated optomechanics is showing potential for precise force measurements. Here, we
report a case study to show experimentally the capacity of such a force sensor, using an …

Nano-mechanical resonators have gained an increasing importance in nanotechnology
owing to their contributions to both fundamental and applied science. Yet, their small …

Abstract Systems of coupled mechanical resonators are useful for quantum information
processing and fundamental tests of physics. Direct coupling is only possible with …

Feedback is a powerful and ubiquitous technique both in classical and quantum system
control. Its standard implementation relies on measuring the state of a system, processing …

Optomechanics, the study of the mechanical interaction of light with matter, has proven to be
a fruitful area of research that has yielded many notable achievements, including the direct …

This paper presents a cavity-assisted coherent feedback scheme to cool a mechanical
resonator to the ground-state in a weak optomechanical coupling setup. Based on the theory …

We consider a wide family of optical coherent feedback loops acting on an optomechanical
system operating in the linearized regime. We assess the efficacy of such loops in improving …

We investigate a system composed of two coupled oscillators subject to stochastic
fluctuations in its internal parameters. In particular, we answer the question whether the well …
