A search for light weakly-interacting massive particles with SuperCDMS and applications to neutrino physics
(Massachusetts Institute of Technology, 2015)
Cosmological and astrophysical evidence indicates that 85% of the matter content of the universe is in the form of non-baryonic dark matter. A large number of experiments are currently undertaking searches for weakly-interacting ...
The role of cooperation and dispersal in the evolution of antibiotic resistance
(Massachusetts Institute of Technology, 2015)
Understanding mechanisms of evolution under in real biological systems is a fundamental problem. Natural selection is one of the mechanisms that drive evolution. Due to the natural selection, phenotypes with higher fitness ...
Thermodynamics and solitonic excitations of a strongly-interacting Fermi gas
(Massachusetts Institute of Technology, 2015)
In this thesis, I present experiments that study the thermodynamics and solitonic excitations of a strongly-interacting Fermi gas, realized with 6Li atoms at a Feshbach resonance where the scattering length is large. The ...
Møller scattering at low energy
(Massachusetts Institute of Technology, 2018)
Møller scattering is one of the most fundamental processes in QED. Its knowledge at high precision is necessary for a variety of modern nuclear and particle physics experiments. However, most treatments have neglected the ...
Precision measurement of the boron to carbon ratio in cosmic rays with AMS-02
(Massachusetts Institute of Technology, 2015)
A precision measurement of the Boron to Carbon ratio in cosmic rays is carried out in the range 1 GeV/n to 670 GeV/n using the first 30 months of flight data of AMS-02 located on the International Space Station. Above 20 ...
Non-equilibrium thermodynamics in porous media : battery degradation, and sorption and transport in porous materials
(Massachusetts Institute of Technology, 2015)
Porous media offer many interesting problems in physics and engineering due to the interaction of phase transitions, surface effects and transport. In this thesis I examine two such problems: the degradation of lithium-ion ...
Theoretical investigation of energy alignment at metal/semiconductor interfaces for solar photovoltaic applications
(Massachusetts Institute of Technology, 2015)
Our work was inspired by the need to improve the efficiency of new types of solar cells. We mainly focus on metal-semiconductor interfaces. In the CdSe study, we find that not all surface states serve to pin the Fermi ...
Electroweak physics and evidence for a Higgs boson decaying to a pair of tau leptons with the CMS detector
(Massachusetts Institute of Technology, 2017)
.Studies of the electroweak interactions using final states with leptons in proton-proton collisions at the Large Hadron Collider at [square root of] s = 7 TeV, [square root of] s = 8 TeV, and [square root of] s = 13 TeV ...
Characterization of jets in heavy ion collisions using photons at the LHC with the CMS detector
(Massachusetts Institute of Technology, 2017)
Using the CMS detector at the LHC, a quantitative study of jet energy loss and angular deflection inside the high energy-density medium formed in PbPb collisions is made. Photons are used to measure the initial state of a ...
Fluid dynamics in action
(Massachusetts Institute of Technology, 2016)
In this thesis we formulate an effective field theory for nonlinear dissipative fluid dynamics. The formalism incorporates an action principle for the classical equations of motion as well as a systematic approach to thermal ...
