Research topic & Research Outline
| Topological structures generated by a molecular rotor assembly and their responses to external fields | |
| Recently, the physical properties associating with topology have been enthusiastically studied in the field of condensed matter physics, the concept of which was first introduced as a vortex forming in two-dimensional (2D) systems. Although the vortices have been discovered in superconducting and superfluid thin films, an electrical vortex structure consisting of electric dipole moments has never been found so far. This is because that it has been difficult to create a material that would realize such a structure. Recently, however, a molecular rotor in which the electric dipole moment upon a scaffold tripodal molecule rotates has been developed. The tripodal molecules are arranged in a nested 2D arrangement to form a 2D molecular rotor system, which is exactly the same structure where the vortex was first introduced. In this study, I'll make an attempt on a first observation of the 2D electrical vortex structure expected to emerge in the molecular rotor assembly. Additionally, since the vortex is an electrical one, direct control of the vortex by an electric field is also expected, and these realizations will provide new insights into the field of topology. | |
