The most essential among the numerous results is the observation of the influence of the reduced dimension on the dephasing time. While T2 = 14 fs has been measured for r = 12 nm which is, within the error bars, consistent with the damping contained in the bulk dielectric function, the ...
Nevertheless, it is frequently approximated by an exponential with the reduced time constant T2*. In the following, three cases of apparent transverse relaxation are discussed more closely: (1) Dipolar coupling in a powder as described in Fig. 1. In this case, the shape of the FID deviates ...
The total dephasing time (T2) of the surface plasmon in single Ag colloids is determined to be 10 fs. The present results are compared to previously reported values obtained from ensemble studies of Ag particles and from the line width of the absorption spectrum. Extension of the present ...
The minimal evolution time between two distinguishable states of a quantum system is referred to as quantum speed limit time (QSLT), which determines the maximum speed of dynamical evolution theoretically. Until now, based on Bures angle or relative purity as the distance measure of two ...

We study theoretically the return probability experiment, which is used to measure the dephasing time T2*, in a double quantum dot (DQD) in semiconducting carbon nanotubes with spin-orbit coupling and disorder-induced valley mixing. Dephasing is due to hyperfine interaction with the spins of the ...
optical dephasing timeT 2The homogeneous optical dephasing time T2 for the organic glass system resorufin in ethanol is measured by picosecond two-pulse photon echoes from 1.5 to 11.4 K. A non-power law temperature dependence of T2 is measured. Non-photochemical hole burning (NPHB) linewidths ...

Time constantUltrafast vibrational dephasing dynamics of 9,10-bis(phenylethynyl)anthracene(BPEA) thin films were revealed by femtosecond coherent anti-stokes Raman scattering spectroscopy (fs-CARS). Dephasing times (T2) of 2.60, 2.98, 3.72, and 1.64ps were acquired at 1213, 1300, 1400, and 1478...
