Report

Slow periodic oscillations in time domain dynamics of NO2

Autor: Sanrey, Michael, Joyeux, Marc

Publikováno v: Journal of Chemical Physics 126 (21/02/2007) 074301

We investigated the time domain nonadiabatic dynamics of NO2 on the coupled X2A1 and A2B2 electronic states by launching wave packets on the excited electronic state and focused on the evolution at long times (t>200 fs), which has received little att

1/f fluctuations of DNA temperature at thermal denaturation

Autor: Joyeux, Marc, Buyukdagli, Sahin, Sanrey, Michael

Publikováno v: Physical Review E, 75 (2007) 061914

We theoretically investigated the temperature fluctuations of DNA close to denaturation and observed a strong enhancement of these fluctuations at the critical temperature. Although in a much lower frequency range, such a sharp increase was also repo

Report

Quantum mechanical and quasiclassical investigation of the time domain nonadiabatic dynamics of NO2 close to the bottom of the X2A1-A2B2 conical intersection

Autor: Sanrey, Michaël, Joyeux, Marc

Publikováno v: Journal of Chemical Physics, 125 (2006) 014304

We use the effective Hamiltonian that we recently fitted against the first 306 experimentally observed vibronic transitions of NO2 [J. Chem. Phys. 119, 5923 (2003)] to investigate the time domain nonadiabatic dynamics of this molecule on the coupled

Classical and quantum mechanical plane switching in CO2

Autor: Sanrey, Michaël, Joyeux, Marc, Sadovskii, Dmitrii A.

Publikováno v: Journal of Chemical Physics 124 (2006) 074318

Classical plane switching takes place in systems with a pronounced 1:2 resonance, where the degree of freedom with lowest frequency is doubly-degenerate. Under appropriate conditions, one observes a periodic and abrupt precession of the plane in whic

Towards more realistic dynamical models for DNA secondary structure

Autor: Buyukdagli, Sahin, Sanrey, Michaël, Joyeux, Marc

Publikováno v: Chemical Physics Letters 419 (2006) 434

We propose a dynamical model for the secondary structure of DNA, which is based on the finite stacking enthalpies used in thermodynamics calculations. In this model, the two strands can separate and the bases are allowed to rotate perpendicular to th
