Modify Gravity

In this talk, we review theories that modify gravity at cosmological distances, and show that any such theory must exhibit a strong coupling phenomenon. We show that all consistent theories that modify the dynamics of the spin-2 graviton on asymptotically flat backgrounds, automatically have this property. Due to the strong coupling effect, modification of the gravitational force is source-dependent, and for lighter sources sets in at shorter distances. This universal feature makes modified gravity theories predictive and potentially testable by precision gravitational measurements at scales much shorter than the current cosmological horizon.

Strong Coupling Effect

A “click” chemistry strategy is used to construct an all-pH efficient hydrogen evolution reaction (HER) catalyst with engineered unsaturated sulfur edges via a strong coupling effect between ultrafine Pd ensembles and Co-MoS2 nanosheets.

<i>para</i>-nitrophenyl acetate hydrolysis is studied under vibrational strong coupling in a Fabry-Perot cavity. By tuning the cavity resonance to the C=O vibrational stretching mode of both the reactant and solvent molecules, it is found that the reaction is accelerated by an order of magnitude. It is shown that this cavity catalysis involves a co-operative strong coupling effect between the solvent and reactant molecules. The reaction rate follows an exponential relation with respect to the solvent coupling strength. The combination of co-operative effects and cavity catalysis confirms the potential of VSC as a new frontier in chemistry. <br>
