Asymmetrical temporal dynamics of edge modes in Su-Schrieffer-Heeger lattice with Kerr nonlinearity
Ghada Alharbi, Stephan Wong, Yongkang Gong +1
Optical bistability and oscillating phases exist in a Sagnac interferometer and a single ring resonator made of nonlinear medium where the refractive indices are modulate…
Probing topology in nonlinear topological materials using numerical -theory
Stephan Wong, Terry A. Loring, Alexander Cerjan
Nonlinear topological insulators have garnered substantial recent attention as they have both enabled the discovery of new physics due to interparticle interactions, and may have a…
A machine learning approach to drawing phase diagrams of topological lasing modes
Stephan Wong, Jan Olthaus, Thomas K. Bracht +2
Identifying phases and analyzing the stability of dynamic states are ubiquitous and important problems which appear in various physical systems. Nonetheless, drawing a phase diagra…
Modelling spatio-temporal dynamics of chiral coupling of quantum emitters to light fields in nanophotonic structures
Jan Olthaus, Maximilian Sohr, Stephan Wong +2
A quantum emitter placed in a nanophotonic structure can result in non-reciprocal phenomena like chiral light excitation. Here, we present a theoretical model to couple circularly…
Phase transitions of non-Abelian charged nodal links in a spring-mass system
Haedong Park, Stephan Wong, Adrien Bouhon +2
Although a large class of topological materials have uniformly been identified using symmetry properties of wave functions, the past two years have seen the rise of multi-gap topol…
Non-Abelian charged nodal links in dielectric photonic crystal
Haedong Park, Stephan Wong, Xiao Zhang +1
A nodal link is a special form of a line degeneracy (a nodal line) between adjacent bands in the momentum space of a three-dimensional topological crystal. Unlike nodal chains or k…
