Plasmonic metamaterial time crystal
Abstract Spatial photonic crystals (SPCs) are unique structures for light–matter interactions because they achieve a large and spatially periodic dielectric contrast on wavelength scales1,2,3,4. Their temporal analogues, photonic time crystals (PTCs), promise similar advances by periodically modulating optical properties in time5,6,7,8,9,10,11, but require strong, ultrafast modulation, which is challenging to obtain experimentally5,12,13,14,15.
Terahertz-Driven Ultrafast Dynamics of Rare-Earth Nickelates by Controlling Only the Charge Degree of Freedom
An important strategy for understanding the microscopic physics of strongly correlated systems and enhancing their technological potential is to selectively drive the fundamental degrees of freedom out of equilibrium. Intense terahertz (THz) pulses with photon energies of a few meV, can not only serve this purpose, but also unravel their electronic and quantum nature.
Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom
1 Introduction With the availability of laser- and accelerator-based intense terahertz (THz) sources, the realization of nonlinear light-matter interaction has extended into the THz regime in recent years, though it is still in its nascent phase.[1, 2] The use of intense THz pulses as a pump – driving a system out of equilibrium – has shown diverse applicability, e.g. in the selective drive of soft phonon modes, thereby inducing ferroelectricity,[3] ultrafast switching of...
