Friction under microscope with trapped ions in optical lattices
(Massachusetts Institute of Technology, 2016)
In recent years, cold-atom experiments have moved towards atomic systems with increasingly stronger interactions. One goal is to emulate condensed-matter phenomena in an ultimately controlled system by studying the motion ...
Generation and Measurement of Entangled Atomic Ensembles with an Optical Cavity
(Massachusetts Institute of Technology, 2015)
Atomic interferometers have a resolution limit set by the projection noise in measurements on ensembles of uncorrelated atoms. To overcome this classical limit and extend precision measurements into the quantum regime, we ...
Probing and preparing novel states of quantum degenerate rubidium atoms in optical lattices
(Massachusetts Institute of Technology, 2013)
Ultracold atoms in optical lattices are promising systems to realize and study novel quantum mechanical phases of matter with the control and precision offered by atomic physics. Towards this goal, as important as engineering ...
Experimental studies of hybrid photonic band gap accelerator structures
(Massachusetts Institute of Technology, 2016)
This thesis reports the first high power tests of a hybrid photonic band gap (PBG) accelerator structure. PBG structures can support a single electromagnetic mode, thus damping higher-order modes (HOMs) generated by ...
Introducing spin-orbit interaction in graphene
(Massachusetts Institute of Technology, 2018)
The excellent electron properties of graphene, an atomically-thin material with record-high carrier mobility and gate tunability, make it central to modern nanoscience. However, the spin-orbit interaction (SOI) naturally ...
Electroweak symmetry breaking in the era of the Higgs boson discovery
(Massachusetts Institute of Technology, 2014)
In this thesis we study possible deviations from the electroweak symmetry breaking mechanism as predicted by the Standard Model (SM), and we introduce a new framework to analyze hadronic final states at colliders. In the ...
Supersymmetry at the dawn of the LHC era
(Massachusetts Institute of Technology, 2014)
In this thesis, I explore various experimental, theoretical, and observational consequences of supersymmetry (SUSY). I show how copious production of Higgs bosons in SUSY events at the LHC can be a striking signal of ...
Nucleon structure and Its modification in nuclei
(Massachusetts Institute of Technology, 2018)
Inclusive electron scattering experiments using fixed targets are an important tool for studying the structure of the nucleons. The electromagnetic structure of the proton, as encapsulated by its elastic form factors, can ...
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 ...
