We report the observed photon bunching statistics of biexciton cascade emission at zero time delay in single quantum dots by second-order correlation function g(2) (T) measurements under continuous wave excitation...
We investigate the behavior of two-dimensional (21)) atom localization in a three-level cascade-type atomic system via measuring the probe absorption. It is found that the precision of the atom localization can be ...

We present the detection of hydrogen sulfide(H_(2)S)in a quantum cascade laser(QCL)based gas sensing system employing direct laser absorption spectroscopy.The sensitivity is obtained to be 3.61×10^(−6) cm^(−1)Hz^(−1/...
A new method is used to compute the fission cross sections in which a change of the ratio of the level density parameter in fission to neutron emission channels is taken into account with the change of the incident en...
