Abstract: The ytterbium monohydroxide is a promising molecule for a new physics searches. It is well known that levels of the opposite parity, separated by the energy split, so-called $l$-doublets, define the experimental electric field strength required for the molecule polarization. In addition, in our previous paper [Phys.Rev. A 105, L050801 (2022)] we have shown that the value of $l$-doubling directly influences the sensitivity of linear triatomic molecules to the $\mathcal{P}$,$\mathcal{T}$-odd effects. In our work [The JCP 155, 164301 (2021)] we have calculated the value of $l$-doubling for the YbOH molecule with approximation of fixed O-H bond length. Accounting the importance of this property, in the present study we consider the additional degree of freedom corresponding to the ligand (OH) deformation.

Analytical Correlation in the H$_{2}$ Molecule from the Independent Atom Ansatz [49.1574468325115]
The total energy functional correctly dissociates the H-H bond and yields absolute errors of 0.002 $rA$, 0.19 eV, and 13 cm-1$ relative to experiment at the tight binding computational cost. The chemical bond formation is attributed to the Heitler-London resonance of quasi-orthogonal atomic states with no contributions from kinetic energy or charge accumulation in the bond.

Vibropolaritonic Reaction Rates in the Collective Strong Coupling Regime: Pollak-Grabert-H\"anggi Theory [0.0]
We show that the Pollak-Grabert-H"anggi (PGH) theory fails to capture the ensemble effects present in experiments. We show how this model succumbs to the polariton "large $N$ problem", that is, the situation whereby the single reacting molecule feels only a tiny $1/N$ part of the collective light-matter interaction intensity.

Triatomic molecule RaOH combines the advantages of laser-coolability and the spectrum with close opposite-parity doublets. We obtain the rovibrational wave functions of RaOH in the ground electronic state and excited vibrational state using the close-coupled equations derived from the adiabatic Hamiltonian.
