Plentiful abutting functional groups boosting sodium storage in a small molecule Organic electrode materials (OEMs), particularly small molecules, are promising for the next-generation batteries due to their advantages of mass production with potentially low cost, flexibility, high capacity, and facile molecular design. However, small molecules usually have high solubility in organic electrolytes, resulting in low actual capacity and poor cyclability.

With an increasing number of experiments observing phonon thermal Hall effect in magnets, it is theoretically desired to have a minimal model for the phonon thermal Hall effect. In this work, we study a simple model of acoustic phonons and uncorrelated paramagnetic doublets. When the doublets are non-Kramers, a linear pseudospin-phonon coupling is allowed by time-reversal symmetry and yields resonant phonon-pseudospin scattering.
