• Title: Orientational decoherence within molecules and emergence of the molecular shape
• Authors: Edit Matyus and Patrick Cassam-Chenai
• Abstract summary: The electrons of the molecule are considered as continuously monitoring agents for the nuclei. The numerical examples suggest that the electron-nucleus Coulomb interaction is sufficient for inducing a blurred shape with strong quantum coherences in compounds of the lightest elements.

• Abstract: The question of classicality is addressed in relation with the shape of the nuclear skeleton of molecular systems. As the most natural environment, the electrons of the molecule are considered as continuously monitoring agents for the nuclei. For this picture, an elementary formalism of decoherence theory is developed and numerical results are presented for few-particle systems. The numerical examples suggest that the electron-nucleus Coulomb interaction is sufficient for inducing a blurred shape with strong quantum coherences in compounds of the lightest elements, H$_2$, D$_2$, T$_2$, and HeH$^+$.

  Isolated atoms as well as molecules at equilibrium are presumed to be simple from the point of view of quantum computational complexity. We show that the process of chemical bond formation is accompanied by a marked increase in the quantum complexity of the electronic ground state.

  We develop here the semiclassical theory of molecular-vibration-polariton dynamics based on the truncated Wigner approximation (TWA) The validity of TWA is examined by comparing it with the fully quantum dynamics of a single-molecule system. The collective and resonance effects of molecular-vibration-polariton formation on the nuclear dynamics are observed in a system of many molecules.

  Previous works usually generate atoms in an auto-regressive way, where element types and 3D coordinates of atoms are generated one by one. In real-world molecular systems, the interactions among atoms in an entire molecule are global, leading to the energy function pair-coupled among atoms. In this work, a generative diffusion model for molecular 3D structures based on target proteins is established, at a full-atom level in a non-autoregressive way.

I introduce a simple approach to capture the collective nature while retaining the full ab initio representation of single molecules. I illustrate that the influence of collective strong coupling on chemical reactions features a nontrivial dependence on the number of emitters.
