Topological Localisation in Time from PT Symmetry
Tom Sheppard, C. B. B. Camacho, Sebastian Weidemann +4
Time has entered the domain of topological phases in the field of non-Hermitian physics. Previous studies have relied on periodic modulation in time to make an intuitive connection…

Disorder-immune momentum band winding topology
Andrea Steinfurth, Sebastian Weidemann, Julia Görsch +4
Time is the odd dimension out: Unlike space, it follows the arrow of time, forbidding back-reflections and requiring momentum yet not energy conservation. Tailored temporal variati…

Drive-induced Non-local Interactions and Topological Bulk Transport of Extended Doublons
Julius Beck, Matthias Heinrich, Marcus J. Meschede +6
The existence of boundary states and their protection against symmetry-preserving perturbations are a hallmark feature of topological systems. While this concept originally emerged…
