“…As shown in Figure 8, we can see that even

N = 9

, there is still an observable and clear prethermalization. It is reported that up to 11 micro(nano)spheres can be trapped collectively, more than 50 atoms can be trapped and manipulated . Furthermore, the trapping frequency of each nanosphere can be adjusted, which indicates our protocol is promising for existing experimental technologies.…”

“…Multiple dielectric particles can be levitated simultaneously, and the optical fields can generate forces between them in a phenomenon called “optical binding”, which may induce the self‐organization phenomenon . While there are several studies on optical binding of the particles in liquid, the optically bonded dielectric particles in vacuum have just begun to attract attention.…”

Recent advances in levitated optomechanics have brought new opportunities for the study of macroscopic quantum mechanics and precision measurement. Previous studies have mainly focused on the single levitated nanoparticle, the systems of multiple levitated nanoparticles were rarely involved. Here an array of optically levitated nanospheres in vacuum is considered and nontrivial phonon transport in this system is investigated. The levitated nanospheres are coupled by optical binding. Key parameters of this system, such as the interaction range, trapping frequencies, and mechanical dissipation, are highly tunable. Due to these advantages, counter‐intuitive phenomena such as prethermalization and nonreciprocal phonon transport can be achieved by tuning the spacing between neighboring spheres, the mechanical dissipation, and the trapping frequency of each sphere. The system provides a great platform to investigate novel phonon transport and thermal energy transfer.

“…Optically induced rotation can be due to optical torque [25,26] on mechanically stabilized (although such stabilization can entail losses or multiple drains) or optically levitated objects (accessible for sub-kg systems and length scales down to the diffraction limit) [26,31,32]. While optical levitation has not been applied to a photonic crystal, several promising experiments [33,34] on the rotation and translation of arrays of trapped particles suggest that this is feasible.…”

A topological wave transistor protected by the Euler characteristic

Although topological materials have recently seen tremendous development, their applications have remained elusive. Simultaneously, there exists considerable interest in pushing the limits of topological materials, including the exploration of new forms of topological protection and the establishment of topologically protected order in non-electronic systems. Here we develop some novel forms of topological order (i.e. topological charges), primarily the Euler characteristic as well as manifold class. We further demonstrate that these topological orders can protect bulk current transmission, even when the topologically trivial phase possesses an arbitrarily large band gap. Such a transition between topologically trivial, periodic dispersion and topologically non-trivial, aperiodic dispersion can be obtained by the anomalous Doppler shift of waves in a gapped periodic medium. Since a waves momentum can induce an anomalous Doppler shift, we thus establish that such a transition can be used to construct a truly rigorous transistor (i.e. with switching and gain) for bosonic waves (light, sound, etc.) and that such a transistor should be experimentally realizable. Our work suggests that additional topological charges may become relevant in moving beyond topological electronics.

“…Unable to further pursue this research with the technology of his time, Ashkin urged researchers to resolve the puzzle of the colliding droplets with high-speed photography. Recently, there has been renewed interest in this attempt [7][8][9]. Notably, Moore et al [8] have observed oscillations of two silica particles for up to a few minutes.…”

We discovered that when a pair of small particles is optically levitated, the particles execute a dance whose motion resembles the orbits of balls being juggled. This motion lies in a plane perpendicular to the polarization of the incident light. We ascribe the dance to a mechanism by which the dominant force on each particle cyclically alternates between radiation pressure and gravity as each particle takes turns eclipsing the other. We explain the plane of motion by considering the anisotropic scattering of polarized light at a curved interface.
