  • Noether identities in gravity theories with nondynamical backgrounds and explicit spacetime symmetry breaking

    Physical Review D

    Gravitational effective field theories with nondynamical backgrounds explicitly break diffeomorphism and local Lorentz invariance. At the same time, to maintain observer independence the action describing these theories is required to be mathematically invariant under general coordinate transformations and changes of local Lorentz bases. These opposing effects of having broken spacetime symmetries but invariance under mathematical observer transformations can result in theoretical inconsistency…

    Gravitational effective field theories with nondynamical backgrounds explicitly break diffeomorphism and local Lorentz invariance. At the same time, to maintain observer independence the action describing these theories is required to be mathematically invariant under general coordinate transformations and changes of local Lorentz bases. These opposing effects of having broken spacetime symmetries but invariance under mathematical observer transformations can result in theoretical inconsistency unless certain conditions hold. The consistency constraints that must hold originate from Noether identities associated with the mathematical observer invariances in the action. These identities are examined in detail and are used to investigate gravity theories with nondynamical backgrounds, including when a Stückelberg approach is used. Specific examples include gravity theories with fixed scalar or tensor backgrounds, Einstein-Maxwell theory with a fixed external current, and massive gravity.

  • Senior Thesis: Gauge Theories and Symmetry Breaking in Massive Gravity

    - Present

    My thesis focuses on Gauge Theories and Symmetry Breaking in Massive Gravity. Specifically, we explore applications of Noether’s Theorems to dRGT Massive Gravity, where the problem of explicit symmetry breaking is repaired by introducing Stuckelberg Fields.

We achieved this by measuring the lifetimes of emitters distributed on nanostructured semiconductor membranes. The project involved assembling, aligning and operating an optics setup, as well as programming the experimental setup as to automatize data collection. In addition, a large portion of the project also focused and data analysis and interpretation of the results as compared to the literature. Another part of the experience focused on the interaction in an international scientific environment, which was done through weekly progress meetings with the group, as well as scientific discussions, presentations and colloquia.

    YouAd is a company founded in 2015, by a group of passionate and dedicated students as a joint business venture. We provide companies with the opportunity to advertise their products and services in an unconventional and innovative setting. We aim to take advantage of the unutilized space offered by hosts around the world who rent or share their living/office spaces in the ever-growing sharing economy. We serve as an intermediary between companies seeking more advertising opportunities and hosts/renters seeking additional income. The sophisticated YouAd platform, comprised of a website and a mobile application, serves as a bridge between companies and hosts/renters. The integration of these two groups inevitably leads to a breakthrough in the world of marketing. YouAd possesses a comprehensive database of hosts and renters which enables the advertising campaigns to successfully reach their target audiences and goals. We identify the optimal advertising locations for our clients from the space sharing websites based on a set of metrics including location, rating and target demographic. I founded and competed with YouAd in the Colby Entrepreneurial Alliance Grant Competition, a seed funding competition for start-ups based at Colby College. This involved preparing a company pitch, which consisted of designing a high-quality presentation, writing the accompanying pitch and delivering it in front of an audience and a panel of judges.
