Ultrafast linear and non-linear spectroscopy : from biological light-receptors to artificial light-harvesting systems
In the experiments presented in this work, linear and non-linear femtosecond time-resolved spectrsocopy were applied to investigate the structure-function and functiondynamics relationship in biological and artificially designed systems. The experiments presented in this work utilize femtosecond …

Theory of terahertz generation by optical rectification
… acceleration, coherent X-ray generation and non-linear spectroscopy. Intra-pulse difference frequency generation or optical rectification of ultrafast optical pump pulses in nonlinear crystals has emerged as the most efficient approach for high-field THz generation. Earlier theoretical …

Iterative path integral calculations of non-linear spectra and entanglement dynamics
… an exponential scaling in simulation time with a linear scaling. This method is applied to calculate the dynamics of two model systems. The first consists of two-qubits interacting with a common bath. In this case we observe a variety of entanglement effects. If the qubits are initially separable, …

Optical nano-antennas: Fabrication, characterization and applications
… in gaps of closely coupled bowties are used in non-linear signal generation and several sum-frequency phenomena are identified. The sub-wavelength confinement of fields in optical antennas requires new techniques that can image beyond diffraction limited optical imaging. One such technique, …
