INTRODUCTION. In clinical practice, stress tests are carried out to draw up an individual patient rehabilitation plan, assess tolerance and optimize the load, and evaluate its clinical effectiveness. The Six-minute walk test (6MWT), in the presence o

We present a hybrid trapping platform that allows us to levitate a charged nanoparticle in high vacuum using either optical fields, radio-frequency fields, or a combination thereof. Our hybrid approach combines an optical dipole trap with a linear Pa

All three motional modes of a charged dielectric nanoparticle in a Paul trap are cooled simultaneously by direct feedback to temperatures of a few millikelvins. We test two methods, one based on electrical forces and the other on optical forces; for

We confine a microparticle in a hybrid potential created by a Paul trap and a dual-beam optical trap. We transfer the particle between the Paul trap and the optical trap at different pressures and study the influence of feedback cooling on the transf

We demonstrate three-dimensional sympathetic cooling of the center-of-mass motion of a silica nanoparticle. The nanoparticle is coupled to a feedback-cooled particle in an ion trap. We investigate limits of the process and discuss optimum strategies.

The efficiency with which the position of a levitated nanoparticle is detected is one factor that sets the minimum temperature of the particle’s center-of-mass motion that can be achieved by feedback cooling. Typically, the detection is based on th

We describe a technique to measure the position of a dipolar scatterer based on self-homodyne detection of the scattered light. The method can theoretically reach the Heisenberg limit, at which information gained about the position is constrained onl

The field of levitated optomechanics studies the interaction between light and the mechanical motion of mesoscopic objects that are suspended by means of magnetic, optical, or electrodynamic traps. The lack of a clamping structure drastically reduces

Levitated particles are unique among optomechanical systems in that they benefit from the absence of physical contact with the external environment. Recently, a new research direction known as levitated optomechanics has attracted interest in numerou

Mechanical oscillators based on levitated particles are promising candidates for sensitive detectors and platforms for testing fundamental physics. The targeted quality factors for such oscillators correspond to extremely low damping rates of the cen
