Poster 42: Nathan Foulk – Interaction corrections for 2D scattering from a hard disk

<< Return to the Main Page

Faculty mentor: Mikhail Raikh

It is known that the presence of the Fermi sea modifies the scattering of an electron from a point-like impurity. This is due to the Friedel oscillations of the electron density around the impurity. These oscillations create an additional scattering potential for incident electrons. The closer the energy of the incident electron to the Fermi level, the stronger the additional scattering. We study this effect for the case when the impurity is not point-like but rather a hard disk.
