Density Matrix Calculation of Surface Enhanced
... Such quantum calculations can provide useful input in modeling the SERS process, but cannot reflect the delocalized surface plasmon modes (collective motions of the conduction electrons). These are sensitive to the overall particle shape, and are the critical determiners of local field enhancement. ...

Fractional @ Scaling for Quantum Kicked Rotors without Cantori
... Figure 3(a) compares the @ scaling of 2d1 for the 2DKP and the RP-DKP, while Fig. 3(b) shows the average of 2d for steps n 2 to 4. We take the behavior of the first step to indicate the local localization length and of steps 2 to 4 to indicate the properties of the long-ranged scaling. All the ...
