Two-electron quantum ring in short pulses |
Variation of transition probability with the radius R of the QR. The transitions from ground state to various excited states are shown in panels from (a)–(f) for the three different pulse shapes considered. The various other parameters used are I = 8 × 1012 W/cm2, R = 100 a.u., t p = 50 fs, and ω 0 = E 01 – E 00. While in panels from (d)–(f), the external static electric field is 80 kV/cm, there is no electric field in panels (a)–(c). |
