    • Radiation pressure effects in a suspended Fabry-Perot cavity 

      Pelc, Jason, 1984- (Massachusetts Institute of Technology, 2006)
      We report on experimental observation of radiation-pressure induced effects in a high-power optical cavity. These effects play an important role in next generation gravitational wave detectors, as well as quantum non-demolition ...
    • Rating systems and learning 

      Smith, Warren Douglas (Massachusetts Institute of Technology, 1984)
    • Realization of Bose-Einstein condensation with Lithium-7 atoms 

      Yu, Yichao (Massachusetts Institute of Technology, 2014)
      This thesis presents our work on developing and improving the techniques of trapping and cooling an ultra-cold cloud of Lithium-7 atoms and the realization of the Bose- Einstein condensate as a first step to study quantum ...
    • Reconstructing nuclear recoil tracks in the Dark Matter Time Projection Chamber 

      Fedus, William Bradley (Massachusetts Institute of Technology, 2010)
      Astrophysical evidence indicates that 23% of our universe's energy density is in the form of nonluminous, nonbaryonic matter referred to as dark matter. One theoretically appealing dark matter candidate is the Weakly ...
    • Refining the multi-field effects of Higgs inflation 

      Greenwood, Ross Norman (Massachusetts Institute of Technology, 2012)
      In this thesis, I investigated the extent to which the inclusion of multiple scalar fields in models of Higgs inflation produces observable departures from the single field case. I designed simulations to numerically solve ...
    • Reflection of light from multi-layer films 

      Cutler, Monarch L (Massachusetts Institute of Technology, 1939)
    • The regulation of angular momentum during human walking 

      Gu, Jianwen Wendy, 1981- (Massachusetts Institute of Technology, 2003)
      The conservation of angular momentum provides an elegant model for human walking and might be used to generate stable robotic locomotion if employed by a control algorithm. To examine the extent to which the body regulates ...
    • Relation of electron scattering cross-sections to drift measurement in noble gases 

      Stacey, Blake (Blake C.) (Massachusetts Institute of Technology, 2005)
      We investigate the classic "inverse problem" of extracting collision and scattering cross sections from measurements of electron swarm behavior. A Monte Carlo technique for simulating electron motion through a gas of ...
    • Relativistic interstellar space flight. 

      Fishback, John Ford (Massachusetts Institute of Technology, 1968)
    • Relativistic quantum field in theoretical physics 

      Phan, Trung Van (Massachusetts Institute of Technology, 2015)
      Quantum field theory is the most well-developed tool in theoretical physics to study about the dynamics at microscopic scales, with particles and quantum behaviors. In this thesis I'll review about the construction of ...
    • Resolution effects in the hybrid strong/weak coupling model 

      Hulcher, Zachary R (Massachusetts Institute of Technology, 2017)
      Within the context of a hybrid strong/weak coupling model of jet quenching, we study the consequences of the fact that the plasma produced in a heavy ion collision cannot resolve the substructure of a collimated parton ...
    • Results from five Chandra observations of the normal galaxy NGC 3877 

      Gonzalez, Edgar Raul, 1977- (Massachusetts Institute of Technology, 2004)
      We present the results of five Chandra observations of the normal galaxy NGC 3877. A total of 27 X-ray sources are detected, including SN 1998S. We find 15 sources to be variable during the 646-day period covered by the ...
    • Rigorous fit to the peak region of the thrust distribution 

      Prouty. Jeffrey C (Massachusetts Institute of Technology, 2014)
      We continue the work of Abbate et al. in [1], in which a factorization formula for the thrust distribution in electron-positron collisions was developed in the framework of soft-collinear effective theory. We extend the ...
    • Robustness and infrared sensitivity of various observables in the application of AdS/CFT to heavy ion physics 

      Shi, Yeming (Massachusetts Institute of Technology, 2008)
      We investigate the robustness with respect to the introduction of nonconformality of five properties of strongly coupled plasmas that have been calculated in K = 4 supersymmetric Yang-Mills (SYM) theory at nonzero temperature, ...
    • The role of eddies in buoyancy flux 

      Ring, Michael J., 1979- (Massachusetts Institute of Technology, 2001)
      This thesis explores the role of eddies in determining the stratification of the ocean through a laboratory experiment. The experiment uses a dual-tank apparatus, with a smaller tank sitting inside the larger tank. Both ...
    • Salty development of an optical photoresist 

      Chao, Adam (Adam C.) (Massachusetts Institute of Technology, 2008)
      In this series of experiments, we add salt to a photoresist developer and observe the effect on photoresist contrast. In order to measure contrast, we designed an anti-reflection coating stack to reduce reflections between ...
    • Scanning tunneling spectroscopy of lead-substituted bismuth strontium copper oxide 

      Zimmermann, Michelle (Michelle Anne) (Massachusetts Institute of Technology, 2007)
      The hole-doped cuprate Bi ... is doped with lead to the solubility limit of x = 0.38 and studied using STM/STS in the overdoped regime where Tc < 2K. Despite the high lead content, residual supermodulations are observed ...
    • Scattering and mesons 

      Ramazanoğlu, Fethï Mübïn (Massachusetts Institute of Technology, 2006)
