The first approach relies on a strong-weak and boson-fermion duality that is made manifest with a certain regularization of point-like interactions between fermions in quantum mechanics. The second approach consists in performing a strong-coupling expansion of form factors summations (Lehmann representation).<\/p>\n<hr \/>\n<p><strong>Visio<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Not so long ago, the concept of higher-order topological insulators and superconductors was mentioned for the first time in print (see Viewpoint [1]).<\/p>\n","protected":false},"author":3,"featured_media":0,"template":"","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":""},"tags":[],"tribe_events_cat":[48,313,233],"class_list":["post-7615","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-events","tribe_events_cat-lpt","tribe_events_cat-seminars","cat_events","cat_lpt","cat_seminars"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 -
