Efficient molecular orientation at high temperatures is induced by a terahertz pulse with the help of an intense nonresonant laser prepulse that dissects rotational phase space to narrow filaments. The authors use echo effect synchronize response all filaments, leading much enhanced compared other techniques.

We present an overview of developments using the nonresonant dynamic Stark effect within the fields of time-resolved molecular dynamics and quantum control, drawing on examples from our own recent work. Particular emphasis is placed on the notion that "dynamics" and "control" are not distinct disciplines and that a clear synergy exits between these areas which has, up to now, been somewhat unde...

We investigate for two-Higgs doublet models with intrinsic CP violation in the scalar potential CP-nonconserving eeects in unpolarized ! t t for a range of neutral Higgs boson masses which includes resonant ' production and the subsequent decay of ' ! t t. The importance of taking into account, even in the resonant case, the interference with the nonresonant background is shown. Further, we pro...

We report on a novel high-sensitivity method to characterize and improve mode matching into optical cavities. This method is based on heterodyne detection of cylindrical transverse cavity modes. A specially designed annular-segmented photodiode is used to measure the amplitude of nonresonant modes reflected by the cavity. Our measurements allow us to optimize cavity mode matching to nearly 99.9...

Results on charmed meson production and decay are presented from the Mark III at SPEAR. FE’ sssociated production is observed allowing a direct measurement of the F’mass. A search for the decay D+ + r+u,, in the recoil of hadronically tagged D* decays provides a stringent limit on the pseudoscalar decay constant jo . New results on DoDo mixing from semileptonic Do decays and evidence for a nonr...

Mayer's second cluster integral for the pion gas is calculated in quantum mechanical approach. It is shown that nonresonant repulsive ππ-interactions as well as the finite width of resonances yield important but almost canceling contributions at typical chemical freeze-out temperatures of the hadron gas. The repulsive ππ-interactions to the second cluster integral is identified with Van der Waa...

We consider nonresonant and weakly resonant Hopf bifurcation from periodic solutions and relative periodic solutions in dynamical systems with symmetry. In particular, we analyse phase-locking and irrational torus flows on the bifurcating relative tori. Results are obtained for systems with compact and noncompact symmetry group. In the noncompact case, we distinguish between bounded and unbound...

An exact solution for the problem of interaction between whispering gallery modes of spherical microresonators and a single dipole is presented. It is predicted that experimentally observed spectral doublets associated with this interaction are a part of a triplet whose third component has yet to be observed. It is also shown that the interaction between the dipole and nonresonant whispering ga...
