This work investigates the phases of strongly correlated, two-dimensional metallic systems and their critical behaviors.
Examines charge-density-wave phases in vanadium diselenide using spectral-function-fitting and mean-field phase diagrams.
Analyzes the square-lattice Hubbard model employing few-patch parquet renormalization group methods.
Studies non-Fermi liquids and their dynamics using functional renormalization group techniques.
Solves linearized quantum Boltzmann equations to analyze non-equilibrium modes in itinerant ferromagnets.
Identified a significant region in phase space for charge-density-wave formation in vanadium diselenide.
Few-patch parquet renormalization group methods were insufficient for complex systems like the Hubbard model.
Discovered a bosonic dynamical exponent of z_A = 2 for the non-Fermi liquid with a U(1) gauge field.
Found that the presence of collective modes in non-equilibrium dynamics depends on both universal and non-universal factors.

Thomas Patrick Sheerin (2026) studied this question.
