Computing An Image Of Objects Hiding Behind A Black Hole, Shannon Harding
Computing An Image Of Objects Hiding Behind A Black Hole, Shannon Harding
Honors Program Theses and Projects
Gravitational lensing is the bending of light rays around a black hole. The goal of this project was to produce a computer code that would model light rays coming from a grid of objects set behind a rotating black hole. Using these light rays, we produced an image illustrating how this background of objects would appear to an observer on Earth. This was done by creating a MATLAB code to model the paths of multiple light rays at a time. This code was then used to help check and correct a C++ code that produced an image. Over the semester, …
An Exposition From Four-Vector To Quantum Field Theory, Weverton Dos Santos Alves
An Exposition From Four-Vector To Quantum Field Theory, Weverton Dos Santos Alves
Honors Program Theses and Projects
The goal of this thesis is to research leading mass-generation theoretical models in particle physics; Which is the physics that fundamentally imparts mass on the known elementary particles. Before these mechanisms, all particles are massless quantum fields. As part of a 2021 REU (Research Experience for Undergraduates) and a team investigating quark mass at Jefferson National Lab, I worked on a mechanical design of the Lepton Direction Electromagnetic calorimeter part of the detector upgrade for the Brookhaven National Laboratory. As integral as this effort is, because the theoretical aspects of mass generation and quark mass physics are traditionally beyond what …
Exploring The Interaction Of Minor-Groove-Binder Netropsin With Dna Using Optical Tweezers, Irbazhusain Shaikh
Exploring The Interaction Of Minor-Groove-Binder Netropsin With Dna Using Optical Tweezers, Irbazhusain Shaikh
Honors Program Theses and Projects
Netropsin is an antibiotic that binds in the minor grooves of DNA, which also exhibits anticancer properties. There have been many previous studies that explored the binding of this drug to DNA using traditional methods where an ensemble averaging is used. In this study we explore the interaction of Netropsin with DNA at a single molecule level using dual beam optical tweezers. We trapped and stretched a single DNA molecule using optical tweezers to measure the force experienced by the DNA as a function of extension in the absence and presence of various concentrations of Netropsin. Our results show the …
Understanding Quantum Field Theory And Standard Model To Explore Beyond Standard Model Physics, Alize Sucsuzer
Understanding Quantum Field Theory And Standard Model To Explore Beyond Standard Model Physics, Alize Sucsuzer
Honors Program Theses and Projects
Motivated by the goal of participating in astroparticle physics research in graduate school, we aimed to understand the Standard Model of particle physics and the Feynman diagrams through which particle interactions are described, so that we could learn about the properties of certain astroparticles. The axiomatic principle that governs fundamental physics is manifest covariance, implying that the mathematical forms of the physical laws are the same to all observers. Maintaining covariance requires 4-vector representation using group theoretical techniques based on symmetries, as well as a transition from single-particle quantum physics to many-particle quantum field theory (QFT). The Standard Model of …
