When we approach problems at issue in the natural world, we often come across the concept of symmetry breaking, that is “asymmetry”. For example, the double helix structure of DNA is only right-handed, and elementary particles obtain mass through spontaneous symmetry breaking. Furthermore, asymmetry is also the source of material functions.
In our research area, we will take advantage of the asymmetry of solid crystals to develop nontrivial cross-correlation, and design and create quantum materials with new functions. The results lead to academic revolution in materials science. And then, we aim to build the theory of “asymmetronics” that will make breakthroughs in the material science.
Introduction of the research area
In this research area, we transcend the understanding of electromagnetic effects such as cross-correlation response and non-reciprocal conduction that arose from the asymmetric electronic states in solids by employing the multipole concepts and develop innovative functions.
Recent developments of quantum beam and physical property measurements in high resolution facilitate the visualization of the orders of multipoles and the quantification of the susceptibility to the external fields. We construct a theoretical model describing the cross-correlation mechanism based on the obtained knowledge and it helps us to design new asymmetric quantum matters. We apply this model to molecular clusters, artificial materials, and broader target, to lead the evolution of next-generation materials science and to frame the “asymmetronics”.
In planned research A01, we conduct microscopic analysis using quantum beams, and in A02, we develop new functions by combining microfabrication technology and various macroscopic measurements in high resolution. The theory group B01 constructs basic theoretical models that incorporate many-body effects and designs new materials. In C01, solid crystals are synthesized to develop new asymmetric quantum matters, and in C02, the strategy is to expand the material scales in wider range.
