Non-Hermitian Hopf-bundle Matter

Explore the intriguing world of non-Hermitian Hopf-bundle matter in this 28-minute conference talk by Moon Jip Park from PCS Institute for Basic Science. Delve into the fascinating realm of line excitations in topological phases and their significance in encoding robust topological information. Discover recent findings on the classification of one-dimensional non-Hermitian topological matters through the linking and winding of complex eigenenergy strings. Investigate the emergence of higher-dimensional bundles of linked strings, where every string is mutually linked by all others. Learn about the proposed topological phases of matter characterized by non-Hermitian Hopf bundles and their unique properties. Examine the bulk-boundary correspondence of the Hopf bundle in momentum space and its connection to the higher-order skin effect in real space. Gain insights into this cutting-edge research that pushes the boundaries of our understanding of topological matter and non-Hermitian systems.
