Patchy Colloidal Clusters with Broken Symmetry. J Am Chem Soc. 2021 Aug 25;143 (33):13175-13183. doi: 10.1021/jacs.1c05123. Epub 2021 Aug 15.We demonstrate how broken symmetry DFT (BS-UDFT) can circumvent this issue, well describing the polaron/bipolaron localization in terms of spin densities and structural deformations, thus providing a correct assessment of the electron transport parameters (e.g., reorganization energy), otherwise incorrectly computed at the …Broken flow symmetry explains the dynamics of small particles in ... - PNASGlide-plane symmetry PCWs have been proposed and engineered to combine efficient chiral coupling with strong Purcell enhancement 18,26 as required for example for effective quantum networks, but ...The notion of spontaneous symmetry breaking has been used to describe phase transitions in a variety of physical systems. In crystalline solids, the breaking of certain symmetries, such as mirror symmetry, is difficult to detect unambiguously. Using $1T\text{\ensuremath{-}}{\mathrm{TaS}}_{2}$, we demonstrate here that rotational …Vibrational Polaritons with Broken In-Plane Translational Symmetry. For the calculation of polariton dispersion relations in planar Fabry-Pérot ….
