As an example, a scheme for the preparation of Schr?dinger-cat states in such a process is proposed beyond the weak excitation regime.展开更多

Here we present a treatment based on a corrected bond additivity model to quantitatively interpret the SFG-VS of the air/methanol interface from the IR and Raman spectra of liquid methanol.展开更多
