2D Topological Edge States in Periodic Space-Time Interfaces
Ohad Segal, Yonatan Plotnik, Eran Lustig +4
Topological edge states in systems of two (or more) dimensions offer scattering-free transport, exhibiting robustness to inhomogeneities and disorder. In a different domain, time-m…
Second Harmonic Generation and Nonlinear Frequency Conversion in Photonic Time-Crystals
Noa Konforty, Moshe-Ishay Cohen, Ohad Segal +2
We study the nonlinear process of second harmonic generation in photonic time-crystals, materials with refractive index that varies abruptly and periodically in time, and obtain th…
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…
Generalized Laws of Refraction and Reflection at Interfaces between Different Photonic Artificial Gauge Fields
Moshe-Ishay Cohen, Christina Jörg, Yaakov Lumer +5
Artificial gauge fields enable extending the control over dynamics of uncharged particles, by engineering the potential landscape such that the particles behave as if effective ext…
Kauffman's clock lattice as a graph of perfect matchings: a formula for its height
Moshe Cohen, Mina Teicher
We give an algorithmic computation for the height of Kauffman's clock lattice obtained from a knot diagram with two adjacent regions starred and without crossing information specif…
