Increasing Quantum Communication Rates Using Hyperentangled Photonic States
Liat Nemirovsky-Levy, Uzi Pereg, Mordechai Segev
Quantum communication is based on the generation of quantum states and exploitation of quantum resources for communication protocols. Currently, photons are considered as the optim…
Phase Retrieval of Vortices in Bose-Einstein Condensates
Ron Ziv, Anatoly Patsyk, Yaakov Lumer +3
We propose and demonstrate numerically a measurement scheme for complete reconstruction of the 2D quantum wave function of a Bose-Einstein condensate, amplitude and phase, from a t…
Superluminal k-gap solitons in nonlinear photonic time-crystals
Yiming Pan, Moshe-Ishay Cohen, Mordechai Segev
We propose superluminal solitons residing in the momentum gap (k-gap) of nonlinear photonic time-crystals. These gap solitons are structured as plane-waves in space while being per…
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…
Amplified Emission by Atoms and Lasing in Photonic Time Crystals
Mark Lyubarov, Yaakov Lumer, Alex Dikopoltsev +3
Photonic Time Crystals (PTCs) - dielectric media with their refractive index modulated periodically in time, offer new opportunities in photonics arising from time reflections and…
Light Emission by Free Electrons in Photonic Time-Crystals
Alex Dikopoltsev, Yonatan Sharabi, Mark Lyubarov +5
Photonic time-crystals (PTCs) are spatially-homogeneous media whose electromagnetic (EM) susceptibility varies periodically in time, causing temporal reflections and refractions fo…
