The ytterbium monohydroxide is a promising molecule for a new physicssearches. It is well known that levels of the opposite parity, separated by theenergy split, so-called $l$-doublets, define the experimental electric fieldstrength required for the molecule polarization. In addition, in our previouspaper [Phys.Rev. A 105, L050801 (2022)] we have s...

We consider the massive vector field propagating in the inhomogeneous parity-breaking medium. The transition between the regions with approximately cosntant values of the parity-breaking parameter allows for the states localized on such boundary to occur. The adiabatic change of the background introduces either decay or the amplification of the loc...
An electron electric dipole moment (eEDM) search using laser-coolable triatomics such as YbOH is one of the most sensitive probes for physics beyond the standard model. The eEDM-induced energy shift is proportional to the polarization (P) of the molecule. Similarly to diatomics with an Ω-doubling structure, it was assumed that for triatomics with a...
We study the influence of the rotations and vibrations of the symmetric-top RaOCH3 molecule on its effectiveness as a probe for the P, T-violating effects, such as the electron electric dipole moment and the scalar-pseudoscalar electron-nucleon interaction. The corresponding enhancement parameters Eeff and Es are computed for the ground and first e...
We study the influence of the rotations and vibrations of the symmetric top RaOCH$_3$ molecule on its effectiveness as a probe for the $\mathcal{P}$ and $\mathcal{T}$-violating effects, such as the electron electric dipole moment (eEDM) and the scalar-pseudoscalar electron-nucleon interaction (Ne-SPS). The corresponding sensitivity parameters $E_{\...
We developed the method for calculation of the linear triatomic molecules in the external electro-magnetic field. The method was applied to calculate the sensitivity of the $^{174}$YbOH to the $\mathcal{P}$,$\mathcal{T}$-odd effects in the first excited $v=1$ bending mode. Calculations show that the most of the levels reach less than 50\% efficienc...
The spectrum of triatomic molecules with close rovibrational opposite paritylevels is sensitive to the $\mathcal{P}$,$\mathcal{T}$-odd effects. This makesthem a convenient platform for the experimental search of a new physics. Amongthe promising candidates one may distinguish the YbOH as a non-radioactivecompound with a heavy atom. The energy gap b...

Triatomic molecule RaOH combines the advantages of laser coolability and the spectrum with close opposite-parity doublets. This makes it a promising candidate for experimental study of the P,T violation. Previous studies concentrated on the calculations for different geometries without the averaging over the rovibrational wave function. The paper b...

Quantum chemical (U)PBE0 method is used to investigate the endometallofullerenes Gd@C70, Gd@C82, Gd@C84, and Gd@C90 for different spin states. The equilibrium structural parameters, IR spectra, the chemical bond energies, the electron affinity and vertical ionization potentials are calculated. The analysis of the electron and spin populations of th...
