Journal ArticleDOI
Photonic Floquet topological insulators
Mikael C. Rechtsman,Julia M. Zeuner,Yonatan Plotnik,Yaakov Lumer,Daniel K. Podolsky,Felix Dreisow,Stefan Nolte,Mordechai Segev,Alexander Szameit +8 more
TL;DR: This work proposes and experimentally demonstrate a photonic topological insulator free of external fields and with scatter-free edge transport—a photonic lattice exhibiting topologically protected transport of visible light on the lattice edges.
Journal ArticleDOI
Topologically protected bound states in photonic parity–time-symmetric crystals
Steffen Weimann,Mark Kremer,Yonatan Plotnik,Yaakov Lumer,Stefan Nolte,Konstantinos G. Makris,Mordechai Segev,Mikael C. Rechtsman,Alexander Szameit +8 more
TL;DR: This work shows theoretically and experimentally the existence of states that are localized at the interface between two topologically distinct PT-symmetric photonic lattices, and finds analytical closed form solutions of topological PT-Symmetric interface states.
Journal ArticleDOI
Experimental boson sampling
Max Tillmann,Max Tillmann,Borivoje Dakić,René Heilmann,Stefan Nolte,Alexander Szameit,Philip Walther,Philip Walther +7 more
TL;DR: In this paper, Aaronson and Arkhipov's model of computation with photons in integrated optical circuits was implemented and the authors set a benchmark for a type of quantum computer that can potentially outperform a conventional computer by using only a few photons and linear optical elements.
Journal ArticleDOI
Observation of a Topological Transition in the Bulk of a Non-Hermitian System.
Julia M. Zeuner,Mikael C. Rechtsman,Yonatan Plotnik,Yaakov Lumer,Stefan Nolte,Mark S. Rudner,Mordechai Segev,Alexander Szameit +7 more
TL;DR: The first experimental observation of a topological transition in a non-Hermitian system is presented, and standard methods for examining topological properties, which involve probing edge (or surface) states, are ignored.
Journal ArticleDOI
Generalized bulk–boundary correspondence in non-Hermitian topolectrical circuits
Tobias Helbig,Tobias Hofmann,Stefan Imhof,M. AbdelGhany,Tobias Kiessling,Laurens W. Molenkamp,Ching Hua Lee,Alexander Szameit,Martin Greiter,Ronny Thomale +9 more
TL;DR: In this paper, a non-Hermitian skin effect was observed in a topolectric circuit with respect to the presence of a boundary, and the voltage signal accumulates at the left or right boundary and increases as a function of nodal distance to the current feed.
