Glass microspheres were trapped in water, air, and vacuum with optical tweezers; and a detection system that can monitor the position of a trapped microsphere with Angstrom spatial resolution and microsecond temporal resolution was developed to study the Brownian motion of a trapped microsphere in air over a wide range of pressures. The instantaneous velocity of a Brownian particle, in particular, was measured for the very first time, and the results provide direct verification of the Maxwell-Boltzmann velocity distribution and the energy equipartition theorem for a Brownian particle. For short time scales, the ballistic regime of Brownian motion is observed, in contrast to the usual diffusive regime. In vacuum, active feedback is used to cool the center-of-mass motion of an optically trapped microsphere from room temperature to a minimum temperature of about 1.5 mK. This is an important step toward studying the quantum behaviors of a macroscopic particle trapped in vacuum. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aMicrophysics 606 $aOptical tweezers 615 0$aMicrophysics. 615 0$aOptical tweezers. 676 $a530.475 700 $aLi$b Tongcang$0935772 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910438113003321 996 $aFundamental Tests of Physics with Optically Trapped Microspheres$92108082 997 $aUNINA LEADER 01763nam 2200421z- 450 001 9910346700303321 005 20210212 010 $a1000034598 035 $a(CKB)4920000000094691 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/57441 035 $a(oapen)doab57441 035 $a(EXLCZ)994920000000094691 100 $a20202102d2013 |y 0 101 0 $aeng 135 $aurmn|---annan 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aQuantitative phase-field model for phase transformations in multi-component alloys 210 $cKIT Scientific Publishing$d2013 215 $a1 online resource (263 p. p.) 225 1 $aSchriftenreihe des Instituts für Angewandte Materialien, Karlsruher Institut für Technologie 311 08$a3-7315-0020-5 330 $aPhase-field modeling has spread to a variety of applications involving phase transformations.While the method has wide applicability, derivation of quantitative predictions requires deeper understanding of the coupling between the system and model parameters.
