Abstract
Berry curvature is the key physical trait in Topological Quantum Materials (TQMs). Indeed, a wide variety of TQMs have been discovered and rise of the era of TQM was achieved. Among various topological features appearing in TQMs, the Berry Curvature Dipole (BCD) is a significant and intriguing phenomenon that requests inversion symmetry breaking of the topological systems. Meanwhile, despite the attractiveness of the BCD, the material stages for the BCD are still limited and the temperature range for it is far below room temperature (RT). Furthermore, nonvolatile, i.e., ferroic BCDs have not yet discovered in spite of its prediction in theory. In this presentation, we introduce the successful demonstration of detection of the ferroic BCD at RT in a topological crystalline insulator, PbSnTe. The nonlinear Hall effect is a good probe for the BCD. The magnitude of the BCD largely exceeds that of for example transition metal dichalcogenides. The detailed physics will be discussed in the presentation.
