Impurity in a d-wave superconductor: Kondo effect and STM spectra
Anatoli Polkovnikov, Subir Sachdev, Matthias Vojta
We present a theory for recent STM studies of Zn impurities in the superconductor BSCCO, using insights from NMR experiments which show that there is a net S=1/2 moment on the Cu i…

Reflection of light and heavy holes from a linear potential barrier
Anatoli Polkovnikov, Robert Suris
In this paper we study reflection of holes in direct-band semiconductors from the linear potential barrier. It is shown that light-heavy hole transformation matrix is universal. It…
