I conduct unaffiliated independent research in theoretical high-energy physics (hep-th), focusing on supersymmetric gauge theories, AdS/CFT, and vacuum data in N=4 super Yang-Mills theory.

I have completed two recent manuscripts on the relation between local readouts and trans-local vacuum data in N=4 SYM and related holographic settings. The first establishes a vanishing result for the local 1-point readout in the source-free symmetric vacuum, while showing that trans-local structures such as Wilson loops, mutual information, and conformal correlators remain nonzero. The second studies how much of this residual vacuum structure can be transported to a de Sitter background: protected data transfer exactly when the detector is correctly placed, whereas non-protected data transfer only at the level of scaling classes.

I have also completed an interdisciplinary manuscript connecting engineering, information theory, and philosophy. It gives constructive counter-evidence to Derrida’s concept of différance by using the formal architecture of Transformers together with the mathematical framework of information theory.
