In this work, optical trapping of single beads and self-assembled clusters composed of up to nine beads is achieved using plasmonic nanotweezers fabricated on a silicon nanophotonic waveguide. We statistically analyze the preferred orientations, the probability of occurrence and the stability of the different cluster configurations. We evidence that the presence of two potential barriers along the waveguide edges results in the enhanced stability of some specific cluster configurations. Our results pave the way for further development of hybrid plasmonic-photonic nanotweezers and lab-on-chips.","PeriodicalId":311295,"journal":{"name":"Optical Trapping and Optical Micromanipulation XVIII","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129613799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to single-electron control of the electric charge, these sensors can be made electrically neutral. This not only enables better isolation from electromagnetic noise, but also allows the measurement of electric charges on the order of 10^-4e. This levitated object is used in the search of new physics in regions of parameter space inaccessible by other techniques. This talk will discuss such sensor characterization and capabilities as well as recent results of searches for dark matter, millicharged particles bound to matter and projections for a search for short ranged interactions.","PeriodicalId":311295,"journal":{"name":"Optical Trapping and Optical Micromanipulation XVIII","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132902474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optical tweezers usually rely on the interaction of light and the ‘bulk’ polarizability of the nanoparticle itself. Here we exploit the polarizability of electronic resonances of optical centers embedded in the solid-state matrix to enhance the optical forces. This effect becomes particularly relevant for ensembles of active centers. The emitters being closely packed in a sub-wavelength volume, can act cooperatively, enhancing further the optical forces. This opens the possibility to apply the powerful toolbox of atomic physics for the quantum manipulation of ‘massive’ mesoscopic objects.","PeriodicalId":311295,"journal":{"name":"Optical Trapping and Optical Micromanipulation XVIII","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121161464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
