We investigate the response of multi-layer epitaxial graphene and chemical vapor deposition (CVD)-grown single-layer graphene to strong terahertz (THz) fields. Contrary to theoretical predictions of strong nonlinear response, the transmitted fields e

CNTs exhibit extraordinary nonlinear THz responses upon optical excitation. Its conductivity reduces at intermediate intensities, while soaring elsewhere. Field-effect mobility and carrier multiplications govern the rise and fall of the conductivity.

A terahertz metamaterial consisting of radiative slot antennas and subradiant complementary split-ring resonators exhibits plasmon induced opacity in a narrow spectral range due to the destructive interference between the bright and dark modes of the

Strong THz pulses instantly restore the sharp resonance of coupled plasmonic oscillators quenched by photoexcitation. The THz control of plasmon induced opacity is applicable to sensitive sensing and ultrafast switching in plasmonic devices.

We demonstrate that free-standing multi-walled carbon nanotubes exhibit extraordinary nonlinear terahertz responses upon optical excitation. Terahertz transmission of the photoexcited nanotubes rises in a narrow range of intermediate intensity with i

$^{139}\mathrm{La}$ NMR is suited for investigations into magnetic properties of ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4}$-based cuprates in the vicinity of their magnetic instabilities, owing to the modest hyperfine interactions between $^{139}\mathrm{L

Strong terahertz pulses transiently revive the plasmonic resonance of a nano-antenna-array-patterned GaAs film, which was initially turned off by photoexcitation. The high-field THz effect has potential to ultrafast optical/THz switching in plasmonic
