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…
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…
