Angle resolved photoemission studies of YbRh$_2$(Si$_{1-x}$Ge$_x$)$_2$

YbRh$_2$(Si$_{1-x}$Ge$_x$)$_2$ has attracted a lot of attention as the first Yb-based system with a quantum critical point (QCP) at $x \sim 0.05$. The QCP can be tuned by either magnetic field or chemical substitution, and non Fermi liquid properties have been observed in the vicinity of it. We present high-resolution angle resolved photoemission data on this compound as a function of Ge-doping. The result will be discussed in conjunction with various theoretical proposals on the Fermi surface topology of this material.
