Recent studies have proposed using a geocentric muon spin force to account for the $(g-2)_\mu$ anomaly, with long-range mediator being light axion-like particle. The exhibits CP-violating scalar coupling nucleons and normal derivative muons. Due weak symmetry, this axion inevitably couples neutrinos, providing potential impact on neutrino oscillations. By utilizing data from BOREXINO, IceCube DeepCore, Super-Kamiokande, SNO, we identified that atmospheric can impose stringent constraints...

We investigate a fifth force mediated by light vector boson that couples to lepton spins, characterized axial-vector couplings leptons and nucleons. This interaction generates potential proportional the inner product of spin nucleon-lepton relative velocity vector, feature extensively explored with precision sensors. Employing weak symmetry, we show left-handed charged naturally extend neutrinos, enabling this influence neutrino oscillations. For electron-nucleon couplings, find solar...

If the terrestrial environment is permeated by dark matter, levitation experiences damping forces and fluctuations attributed to matter. This paper investigates levitodynamics with multiple stochastic forces, including thermal drag, photon recoil, feedback, etc., assuming that all of these adhere fluctuation-dissipation theorem. The ratio total coefficient distinguishes from cases involving only one single force. heating cooling processes are formulated determine limits temperature change....
