Resonant dispersive wave emission: a route toward few-cycle, tunable strong-field drivers in the visible
Martin Gebhardt, Joleik Nordmann, Nikoleta Kotsina +4
Intense ultrafast lasers are the backbone of strong-field physics and enable table-top scale applications of coherent high-photon energy radiation through high-harmonic generation…
Experimental observation of energy-band Riemann surface
Dali Cheng, Heming Wang, Janet Zhong +3
Non-Hermiticity naturally arises in many physical systems that exchange energy with their environment. The presence of non-Hermiticity leads to many novel topological physics pheno…
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…
