Artificial gauge fields in the t-z mapping for optical pulses: spatio-temporal wavepacket control and quantum Hall physics
Christopher Oliver, Sebabrata Mukherjee, Mikael C. Rechtsman +2
We extend the mapping formalism of time-dependent paraxial optics by identifying configurations displaying a synthetic magnetic vector potential, leading to a non-trivial ban…
Coexistence of stable and unstable population dynamics in a nonlinear non-Hermitian mechanical dimer
Enrico Martello, Yaashnaa Singhal, Bryce Gadway +2
Non-Hermitian two-site ``dimers'' serve as minimal models in which to explore the interplay of gain and loss in dynamical systems. In this paper, we experimentally and theoreticall…
