The effect of solvent dynamics on the low frequency collectivemotions of DNA in solution and unoriented films
Abstract
Infrared spectroscopy is used to probe the dynamics of invitro samples of DNA prepared as solutions and as solid unoriented films.The lowest frequency DNA mode identified in the far-infrared spectra ofthe DNA samples is found to shift in frequency when the solvent influencein the hydration shell is altered. The lowest frequency mode also hascharacteristics that are similar to beta - relaxations identified inother glass forming polymers.

Direct dynamics for free radical kinetics in solution: Solvent effect on the rate constant for the reaction of methanol with atomic hydrogen
Recent years have seen great progress in modeling solvation effects on chemical reactions, especially ionic reactions and polar rearrangements. Radical chain reactions, in which a radical abstracts an atom from a molecule which is thereby converted to a radical, are an important class of reactions that has been less well studied. Such bimolecular radical substitution (S{sub R}2) reactions typically have smaller solvent effects than ionic reactions, and thus they provide a sensitive test of theory. The authors calculate the rate constant for the reaction {sup {sm_bullet}}H + CH{sub 3}OH {yields} H{sub 2} + {sup {sm_bullet}}CH{sub 2}OH both in the gasmore » -
Thermal fluctuation and 1/ f noise in oriented and unoriented Y sub 1 Ba sub 2 Cu sub 3 O sub 7 minus x films
We report on electrical noise measurements made on YBCO (Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}}) films on SrTiO{sub 3}, on bulk silicon with a ZrO{sub 2} buffer layer, and on thin dielectric membranes. We have found that 1/{ital f} noise predominates in the unoriented films and that thermal fluctuation noise is the chief source of noise in good films on SrTiO{sub 3}. -
Low-frequency electron dynamics in the near field of a Hall effect thruster
Time-resolved electrostatic probe measurements were performed in the near field of a SPT100-ML Hall effect thruster in order to investigate electron properties changes on a microsecond time scale. Such measurements allow one to monitor the electron temperature T{sub e}, the electron density n{sub e}, as well as the plasma potential V{sub p} during a time period that corresponds to one cycle of a breathing-type plasma oscillation with f{approx_equal}15-30 kHz. Although T{sub e}(t) stays constant in time, n{sub e}(t) and V{sub p}(t) oscillate with the discharge current waveform frequency. The observed time delay between n{sub e} and anode discharge current (Id{submore » -
Dynamics and quantum Zeno effect for a qubit in either a low- or high-frequency bath beyond the rotating-wave approximation
We use a non-Markovian approach to study the decoherence dynamics of a qubit in either a low- or high-frequency bath modeling the qubit environment. This is done for two separate cases: either with measurements or without them. This approach is based on a unitary transformation and does not require the rotating-wave approximation. In the case without measurement, we show that, for low-frequency noise, the bath shifts the qubit energy toward higher energies (blue shift), while the ordinary high-frequency cutoff Ohmic bath shifts the qubit energy toward lower energies (red shift). In order to preserve the coherence of the qubit, wemore »
