I’m broadly interested in different aspects of quantum theory, especially in how to describe and understand interacting systems out of equilibrium.
A central focus is quantum transport. I develop extensions of Density Functional Theory (i-DFT and iq-DFT), together with many-body approaches like Nonequilibrium Green’s Functions, to study charge and heat transport in nanoscale systems. This includes thermoelectric effects and devices like quantum dots and Cooper pair splitters, where electron interactions and coherence are essential.
I also explore quantum information aspects of physical systems, including entropy, complexity, and their role in high-dimensional quantum states. In addition, I study error characterization in quantum computing, with the goal of improving the precision and stability of quantum simulations.
