pi-kinks in Strongly AC Driven Sine-Gordon Systems (1998)
Vadim Zharnitsky, Igor Mitkov, Niels Grønbech-Jensen, Niels Gr��nbech-jensen
We demonstrate that ß-kinks can exist in non-parametrically AC driven sineGordon systems if the AC drive is sufficiently fast. It is found that, at a critical value of the drive amplitude, there are...
