The recent developments in the generation of optical attopulses suggest that it will soon become experimentally feasible to induce and subsequently directly probe ultrafast charge transfer between the end moieties of modular molecules. One ultrafast pulse creates a non-stationary state of the neutral or of the cation, that can be probed by a second pulse. Such experiments would allow...

Optical-lattice experiments have recently succeeded in probing the geometry of 2D Bloch bands with cold neutral atoms. Beyond these local geometrical effects, which are captured by the Berry curvature, 2D Bloch bands may also display non-trivial topology, a global property captured by a topological invariant (e.g. the first Chern number). Such topological properties have dramatic consequences...

We theoretically explore the dynamic hysteresis behavior of a driven-dissipative photonic resonator with a Kerr-type nonlinearity [1]. In the regime where the semiclassical approach predicts bistability, the exact steady-state density matrix is well known to be unique and a statistical mixture of two states. A direct consequence is that the full quantum treatment predicts no static hysteresis...

Carbon-chain molecules have been detected in many astrophysical environments such as interstellar medium (ISM) and circumstellar envelopes. These molecules can be formed in different processes, such as neutral-neutral, ion-neutral or ion-ion collisions and the demand for accurate molecular data concerning these processes is very strong.
We will present measurements of ion pair dissociation...

The development of efficient fuel cells is a promising strategy to diminish fossil fuel consumption. A major drawback of state-of-the-art proton exchange membrane fuel cells (PEMFCs) is CO poisoning of the platinum catalyst.[1] CO molecules present in the fuel preferentially adsorb to Pt nanoparticles, thereby blocking the active sites and degrading the cell’s performance. Several Pt alloys...

The Lieb-Robinson bound has been a milestone in our understanding of the nonequilibrium dynamics of nonrelativistic short-range interacting quantum systems. In essence it states that the effect of a perturbation at a point A cannot be felt at another point B until a time t=r/v, with r the distance between A and B and v a characteristic velocity in the system. Even though causality is not...
