Dynamics of poles with position-dependent strengths and its optical analogues
نویسندگان
چکیده
Dynamics of point vortices is generalized in two ways. Firstly by allowing complex strengths which allows for sources and sinks in combination with the the usual vorticity, and secondly by allowing the strengths to be functions of position. We describe several exact solutions with optical analogues, notably Snell’s law and law of reflection off a mirror.

In the present work, first an analytic relation for position-dependent effective mass in a quantum rod is obtained. Then, the effect of position-dependent effective mass on the intersubband optical absorption coeffcient and the refractive index change in the quantum rod is examined. Our numerical calculations are performed using both a constant effective mass and the position-dependent effect...
