Determining Electron Wave Functions and Object Potentials in Transmission Electron Microscopy: application to stacks of 2D materials

Up to now transmission electron microscopy (TEM) was more focused on producing images or diffraction patterns of objects. Of course, some pioneering techniques like holography or focal series or ptychography have tried to reconstruct the electron waves functions at the exit surface of the observed objects, but their results and applications were quite limited or, […] >>

Quantum computing and the orthogonality catastrophe

Quantum physics is evolving from a purely academic field towards building actual technologies with potential applications. Among those, the quantum computer is one of the most fascinating possibilities. Operating a quantum computer is however a race against time, as one needs to build up entanglement before decoherence sets in. In this project, we will be […] >>
