Topological phases in narrow-band systems
(Massachusetts Institute of Technology, 2015)
I discuss several novel topological phases in correlated electron systems, realized through spin-orbit interactions and lattice effects especially narrow-band systems. The first realizes the fractional quantum Hall effect ...
Statistical physics of biological self-organization : case studies in protein folding and adaptation to time-varying fields
(Massachusetts Institute of Technology, 2016)
In this thesis, we use the methods of statistical physics to provide quantitative insights into the behavior of biological systems. In the first half of the thesis, we use equilibrium statistical physics to develop a ...
Nanophotonics for tailoring the flow of thermal electromagnetic radiation
(Massachusetts Institute of Technology, 2015)
In this thesis, we explore the interaction of thermal radiation with nano-scale structures. First, we introduce the concept of radiative energy transfer between two objects of different temperatures in the near field, and ...
Measurement of cosmic antiprotons with the alpha magnetic spectrometer aboard the International Space Station
(Massachusetts Institute of Technology, 2017)
A precision measurement of the cosmic antiproton ( -p) flux and the antiproton-to-proton flux ratio ( -p/p) made with the Alpha Magnetic Spectrometer aboard the International Space Station is presented. The measurement ...
Towards spin squeezed ¹⁷¹Yb atomic clock beyond the standard quantum limit
(Massachusetts Institute of Technology, 2017)
State-of-the-art atomic clocks have fractional frequency instability of 6 x 10-17 at 1 s averaging time, and are aiming for even higher stability. One of the main factors limiting this stability is the standard quantum ...
Studies of ICRF mode conversion with phase contrast imaging and full-wave simulations in Alcator C-Mod
(Massachusetts Institute of Technology, 2012)
Radio frequency (rf) waves in the ion cyclotron range of frequencies (ICRF) are widely used for heating fusion plasmas. In a multi-ion-species plasma, the launched fast waves convert to ion cyclotron waves and ion Bernstein ...
Measuring the lepton sign asymmetry in elastic electron-proton scattering with OLYMPUS
(Massachusetts Institute of Technology, 2016)
OLYMPUS is a particle physics experiment that collected data in 2012 at DESY, in Hamburg, Germany, on the asymmetry between positron-proton and electron-proton elastic scattering cross sections. A non-zero asymmetry is ...
Topological materials and quantum entanglement
(Massachusetts Institute of Technology, 2015)
As the title implies, this thesis consists of two main topics: materials which realize topological phases of matter and applications of the concept of entanglement in understanding topological phases and their transitions. ...
Elliptic fibrations among toric hypersurface Calabi-Yau manifolds and mirror symmetry of fibrations
(Massachusetts Institute of Technology, 2019)
In this thesis, we investigate the prevalence of elliptic and genus one fibrations among toric hypersurface Calabi-Yau three folds by (1) constructing explicitly elliptically fibered Calabi-Yau threefolds with large Hodge ...
Effective field theories for the LHC
(Massachusetts Institute of Technology, 2016)
In this thesis I study applications of effective field theories to understand aspects of QCD jets and their substructure at the Large Hadron Collider. In particular, I introduce an observable, D2 , which can be used for ...
