Updated constraints on $\mathcal{T}$,$\mathcal{P}$-violating axionlike-particle-mediated electron-electron and electron-nucleus interactions from HfF$^+$ experiment

Abstract: Recently, upper bounds on the static time-reversal ($\mathcal{T}$) and spatial parity ($\mathcal{P}$)-violating electron electric dipole moment ($e$EDM) and dimensionless constant characterizing the strength of the $\mathcal{T}$,$\mathcal{P}$-violating scalar-pseudoscalar nucleus-electron interaction have been updated in the JILA experiment using the HfF$^+$ cations [T.S. Roussy et al, arxiv:2212.11841 (2022)]. We considered other two sources of the $\mathcal{T}$,$\mathcal{P}$,-violation in HfF$^+$ -- axionlike-particle-mediated (ALP) scalar-pseudoscalar electron-electron and nucleus-electron interactions. To estimate the magnitude of effects, induced by such interactions in HfF$^+$ we have developed and applied a method which implies direct use of the ab-initio relativistic coupled cluster theory to calculate molecular parameters that characterize the interactions. Using these parameters, we showed that an order of magnitude updated laboratory constraints on the ALP-mediated electron-electron and nucleus-electron interactions can be derived from the experimental data on $\mathcal{T}$,$\mathcal{P}$-violating effects in HfF$^+$ for a wide range of ALP masses.
