Temporal Localisation of Waves from Imaginary Line-Gap Topology

Carlos Camacho, Tom Sheppard, Joshua Feis +4

For non-Hermitian Hamiltonians, gain, loss, and non-reciprocity produce complex eigenvalues which, in turn, facilitate different kinds of topological phases. One example is the ima…

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…

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…

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…

Spacetime-topological events

Joshua Feis, Sebastian Weidemann, Tom Sheppard +2

Time is, figuratively and literally, becoming the new dimension for crystalline matter. As such, rapid recent progress on time-varying media gave rise to the notion of temporal and…
