In recent years, there has been an increasing interest in utilizing synthetic (non-spatial) dimensions for experimentally studying topological phenomena in physics. Synthetic dimensions are linked to increasing the dimensionality, inducing long-range connectivity, and other surprising effects in a plethora of physical systems. In this seminar, I will explain how to observe new physics by utilizing these dimensions. I will present our first demonstration of 2D and 3D photonic topological insulators in synthetic dimensions and show how these effects can be used to achieve multi laser mode-locking. Finally, I  will discuss how this approach is linked to “photonic time crystals” and our latest experimental results in observing materials that change their macroscopic behavior abruptly in time
