Three-dimensional photonic topological insulator induced by lattice dislocations
Eran Lustig, Lukas J. Maczewsky, Julius Beck +6
The hallmark of topological insulators is the scatter-free propagation of waves in topologically protected edge channels. This transport is strictly chiral on the outer edge of the…
Populating and probing protected edge states through topology-entailed trivial states
Francesco S. Piccioli, Mark Kremer, Max Ehrhardt +5
Topological insulators enable non-reciprocal light propagation that is insensitive to disorder and imperfections. Yet, despite considerable attention from the photonics community a…
Bimorphic Floquet Topological Insulators
Georgios G. Pyrialakos, Julius Beck, Matthias Heinrich +5
Topological theories have established a new set of rules that govern the transport properties in a wide variety of wave-mechanical settings. In a marked departure from the establis…
Roadmap on Topological Photonics
Hannah Price, Yidong Chong, Alexander Khanikaev +20
Topological photonics seeks to control the behaviour of the light through the design of protected topological modes in photonic structures. While this approach originated from stud…
Nonlinear second-order photonic topological insulators
Marco S. Kirsch, Yiqi Zhang, Mark Kremer +7
Higher-order topological insulators (HOTI) are a novel topological phase beyond the framework of the conventional bulk-boundary correspondence. In these peculiar systems, the topol…
Nonlinearity-induced photonic topological insulator
Lukas J. Maczewsky, Matthias Heinrich, Mark Kremer +8
The hallmark feature of topological insulators renders edge transport virtually impervious to scattering at defects and lattice disorder. In our work, we experimentally demonstrate…
Exploring complex graphs using three-dimensional quantum walks of correlated photons
Max Ehrhardt, Robert Keil, Lukas J. Maczewsky +3
Graph representations are a powerful concept for solving complex problems across natural science, as patterns of connectivity can give rise to a multitude of emergent phenomena. Gr…
Bragg solitons in topological Floquet insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Lukas J. Maczewsky +2
We consider a topological Floquet insulator consisting of two honeycomb arrays of identical waveguides having opposite helicities. The interface between the arrays supports two dis…
Edge Solitons in Lieb Topological Floquet Insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Lukas J. Maczewsky +2
We describe topological edge solitons in a continuous dislocated Lieb array of helical waveguides. The linear Floquet spectrum of this structure is characterized by the presence of…
Topological state engineering via supersymmetric transformations
Gerard Queralto, Mark Kremer, Lukas J. Maczewsky +4
The quest to explore new techniques for the manipulation of topological states simultaneously promotes a deeper understanding of topological physics, and is essential in identifyin…
Extreme defect sensitivity from large synthetic dimensionality
Lukas J. Maczewsky, Kai Wang, Alexander A. Dovgiy +7
The geometric dimensionality of a physical system significantly impacts its fundamental characteristics. While experiments are fundamentally limited to the maximum of three spatial…
Fermionic time-reversal symmetry in a photonic topological insulator
Lukas J. Maczewsky, Bastian Höckendorf, Mark Kremer +5
Much of the recent enthusiasm directed towards topological insulators as a new state of matter is motivated by their hallmark feature of protected chiral edge states. In fermionic…
Observation of Light Guiding by Artificial Gauge Fields
Yaakov Lumer, Miguel A. Bandres, Matthias Heinrich +4
The use of artificial gauge fields enables systems of uncharged particles to behave as if affected by external fields. Generated by geometry or external modulation, artificial gaug…
Observation of photonic anomalous Floquet Topological Insulators
Lukas J. Maczewsky, Julia M. Zeuner, Stefan Nolte +1
Commonly, a two-dimensional topological insulator is characterized by non-zero Chern numbers associated with its band structure. In our work, we present the experimental demonstrat…
