The primary goal of my thesis is to study the interplay between properties of physical systems (mostly for quantum information processing) and the geometry of these systems. The ambient spaces I have been working with are fractal-type graphs. In many cases analytic computations can be done on these graphs due to their self-similarity. Different scenarios are investigated.
Perfect Quantum State Transfer on Graphs and Fractals: We are concerned with identifying graphs and Hamiltonian operators properties that guarantee a perfect quantum state transfer.
Toda lattices on weighted Z-graded graphs: We study discrete one dimensional nonlinear equations and their lifts to Z-graded graphs. We prove the existence of radial solitons on Z-graded graphs.
Snowflake Domain with Boundary and Interior Energies: We investigate the impact of the fractal boundary on the eigenfunctions of a discrete Laplacian on the Koch Snowflake Domain that takes into account both the interior and the fractal boundary.
Harmonic Gradients on Higher Dimensional Sierpinski Gaskets: This project studies the connection between the regularity of a Laplacian of a function and the pointwise existence of its harmonic gradient.
