Self-Consistent Maxwell-Schrödinger Theory

Perturbation methods are powerful semi-analytical methods that can serve for describing physical phenomenon at the regimes of weak interactions. We investigate the domain of degrees of freedom, involving electron-light interactions, and search for parameters for which perturbation analysis as well as eikonal approximations breaks down. As a results of it, an emerging class of physical phenomenon are explored. For this purpose, we develop self-consistent Maxwell-Schrödinger and Maxwell-Dirac numerical toolboxes.

Spectral Interferometry with Electron Microscopes

The ability to control coherent pathways in the transition from initial to final quantum sates has paved the way towards tailoring of chemical interactions, ionization processes, and emergence of boson-sampling devices. Inherent to quantum coherent control is the interference phenomenon that is present for all physical quantities which we call “wave”, such as electron wavepackest. We intend to propose methods for manipulation and characterization of the interferences happening during the interaction of electron wavepackts with nanophotonic systems, and to utilize the results for investigating correlations and couplings between charge density waves in those systems, and to explore charge- and energy-transfer dynamics.

Characterizing Nanophotonic Systems

Control of light-matter interaction at the nanoscale has applications in faster optics-electronics interconnects and miniaturized telecommunications techniques, as well as enhancing the Purcell factor and tailoring the radiation from quantum emitters. We intend to design, fabricate, and characterize high quality nanoresonators and microsystems composed of hybrid systems of metallic, dielectric, and semiconducting 2D and 3D materials. We explore the nanoexcitations in these systems for discovering novel polaritonic systems and using them for manipulating the emission from electron beams, and exploiting them for dynamical electron-optics systems.
