We examine computationally how ultrashort polarized strong one cycle IR pulses can be used for steering coherent nuclear dynamics in LiH. The nuclear motion is described using the time-dependent Schrödinger equation on a grid for several coupled electronic states. The coupling to the strong field of the pump and probe pulses is included in the Hamiltonian as well as the non adiabatic coupling between the different electronic states. LiH possesses low lying Σ and Π states that can be selectively accessed by controlling the polarization of the pump pulse along the bond or perpendicularly to it. In addition, when using a one cycle pulse, controlling the carrier envelope phase (CEP) allows to select the states that will be coherently excited according to their polarity. Since some of the excited Σ states and all the Π states are repulsive, polarization and CEP control of the pump pulse leads to controlling the dissociation yields. In particular, our quantum dynamics simulations show that the ratio of the fragmentation yields of the Σ2 and Σ3 states can be changed by a factor 10 when the CEP of a one cycle IR pulse polarized along the bond is switched from 0 to π. In addition to probing the dynamics by following the fragmentation, we also report on probing the coherent vibronic wave packet using transient absorption spectra that results from the interaction of the molecular transition dipole with the electric fields of the pump and the probe pulses. The emission spectrum retrieves the different time scales of the vibronic dynamics and probes the time evolution of the coherences. © Springer International Publishing AG 2017. [less ▲]

Elucidating the role of quantum coherences in energy migration within biological and artificial multichromophoric antenna systems is the subject of an intense debate. It is also a practical matter because of the decisive implications for understanding the biological processes and engineering artificial materials for solar energy harvesting. A supramolecular rhodamine heterodimer on a DNA scaffold was suitably engineered to mimic the basic donor-acceptor unit of light-harvesting antennas. Ultrafast 2D electronic spectroscopic measurements allowed identifying clear features attributable to a coherent superposition of dimer electronic and vibrational states contributing to the coherent electronic charge beating between the donor and the acceptor. The frequency of electronic charge beating is found to be 970 cm-1 (34 fs) and can be observed for 150 fs. Through the support of high level ab initio TD-DFT computations of the entire dimer, we established that the vibrational modes preferentially optically accessed do not drive subsequent coupling between the electronic states on the 600 fs of the experiment. It was thereby possible to characterize the time scales of the early time femtosecond dynamics of the electronic coherence built by the optical excitation in a large rigid supramolecular system at a room temperature in solution. © 2017 the Owner Societies.

The coupled electronic-nuclear coherent dynamics induced by a short strong VUV fs pulse in the low excited electronic states of HCN is probed by transient absorption spectroscopy with a second weaker fs UV pulse. The nuclear time-dependent Schrodinger equation is solved on a 2D nuclear grid with several electronic states with a Hamiltonian including the dipole coupling to the pump and the probe electric fields. The two internal nuclear coordinates describe the motion of the light H atom. There is a band of several excited electronic states at about 8 eV above the ground state (GS) that is transiently accessed by the pump pulse. We tailored the pump so as to selectively populate the lowest 1A′′ electronic state thereby the pulse creates an electronic coherence with the GS. Our simulations show that this electronic coherence is modulated by the nuclear motion and persists all the way to dissociation on the 1A′′ state. Transient absorption spectra computed as a function of the delay time between the pump and the probe pulses provide a detailed probe of the electronic amplitude and its phase, as well as of the modulation of the electronic coherence by the nuclear motion, both bound and dissociative. © the Owner Societies 2017.

Non-Boolean computations implementing operations on multi-valued variables beyond base 2 allow enhanced computational complexity. We introduce DNA as a functional material for ternary computing, and in particular demonstrate the use of three-valued oligonucleotide inputs to construct a 3 [times] 3 multiplication table. The system consists of two three-valued inputs of -1; 0; +1 and a fluorophore/quencher functional hairpin acting as computational and reporter module. The interaction of the computational hairpin module with the different values of the inputs yields a 3 [times] 3 multiplication matrix consisting of nine nanostructures that are read out by three distinct fluorescence intensities. By combining three different hairpin computational modules, each modified with a different fluorophore/quencher pair, and using different sets of inputs, the parallel operation of three multiplication tables is demonstrated.
