Microwave controlled ground state coherence in an atom-based optical amplifier

We experimentally investigate and theoretically analyze the effect of microwave controlled atomic ground state coherence on the phase-dependent amplification (PDA) of an optical probe field. We use three hyperfine levels in room temperature 85 Rb…

Renormalization of the valence and conduction bands of (C6H5C2H4NH3)2PbI4 hybrid perovskite

Quasi two-dimensional hybrid organic-inorganic perovskites (HOIPs) have been rediscovered recently for photovoltaics due to a higher stability than other HOIPs. We focus here on the electronic structure of the 2D perovskite (C6H5C2H4NH3)2PbI4. We…

Lévitation d’une nanoparticule de diamant dans le vide

Avec les nombreuses applications des pinces optiques, le développement des parti-cules en lévitation dans le vide connaît une période d’essor dans la recherche depuis plusieurs années. Le faible couplage à l’environnement permet d’avoir un système…

Tetrazine-incorporating layered halide perovskites featuring type II electronic interface: a small cation with several optical and electronic resonances

Layered halide perovskites are a class of semiconductors easily produced via chemical approaches and showing unique optical and electronic properties. These materials have a natural quantum-well electronic structure, that is, the band-gap of the…

Supraconductivité

Towards room-temperature superconductivity

By taking advantage of a stability criterion established recently, the critical temperature Tc is reckoned with help of the microscopic parameters, characterising the normal and superconducting electrons, namely the independent-electron band…
