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…
Exciton-polariton topological insulator
S. Klembt, T. H. Harder, O. A. Egorov +9
Topological insulators (TIs) are a striking example of materials in which topological invariants are manifested in robustness against perturbations. Their most prominent feature is…
Photonic Topological Insulator in Synthetic Dimensions
Eran Lustig, Steffen Weimann, Yonatan Plotnik +4
Topological phases enable protected transport along the edges of materials, offering immunity against scattering from disorder and imperfections. These phases were suggested and de…
Observation of Accelerating Wave Packets in Curved Space
Anatoly Patsyk, Miguel A. Bandres, Rivka Bekenstein +1
We present the first experimental observation of accelerating beams in curved space. More specifically, we demonstrate, experimentally and theoretically, shape-preserving accelerat…
Topology of photonic time-crystals
Eran Lustig, Yonatan Sharabi, Mordechai Segev
We introduce topological phases in Photonic Time-Crystals. Photonic Time-Crystals are materials in which the refractive index varies periodically and abruptly in time. When the ref…
Deep Learning Reconstruction of Ultra-Short Pulses
Tom Zahavy, Alex Dikopoltsev, Oren Cohen +2
Ultra-short laser pulses with femtosecond to attosecond pulse duration are the shortest systematic events humans can create. Characterization (amplitude and phase) of these pulses…
