Abstract:  The ability to slow down or enhance chemical reactions, by a seemingly simple setup of reactions inside a dark (no photons) cavity made of two parallel mirrors is fascinating. Unfortunately, currently, theory and experiment have not yet fully converged. Since theory and experiment perfectly match for atom/molecular collisions in gas phase the enhancing chemical reactions in gas phase through its coupling to quantize electromagnetic modes in a dark cavity is investigated. Here the conditions and guidelines for selecting the proper type of reactions that can be enhanced by a dark cavity are provided. Showing that the asymmetric reaction rates of O + D2 → [ODD] # → OD + D and H + ArCl → [ArHCl] # → H + Ar + Cl can be enhanced by a dark cavity. On the other hand, an effect of the dark cavity on the symmetric reaction of hydrogen exchange in methane is predicted to be negligible.

Notice that the theory is not limited to microwave cavities only.

Professor Emeritus of Chemistry and Theoretical Physics at the Technion, he authored the first book ever written on non-Hermitian quantum mechanics, published in 2011 by Cambridge University Press, as well as two volumes in Hebrew on quantum mechanics, covering foundations to applications, published by Magness Press. In his work, he introduced new concepts in non-Hermitian quantum mechanics, such as the C-product and self-orthogonality, and, together with his collaborators, pioneered fields like light-induced conical intersections, time asymmetrical optical and electrical switches, and explored various effects of exceptional points on AMO physical phenomena
