Local inhomogeneities resolved by scanning probe techniques and their impact on local 2DEG formation in oxide heterostructures
M. -A. Rose, J. Barnett, D. Wendland +6
Lateral inhomogeneities in the formation of 2-dimensional electron gases (2DEG) directly influence their electronic properties. Understanding their origin is an important factor fo…

Screened activity expansion for the grand-potential of a quantum plasma and how to derive approximate equations of state compatible with electroneutrality
A. Alastuey, V. Ballenegger, D. Wendland
We consider a quantum multi-component plasma made with S species of point charged particles interacting via the Coulomb potential. We derive the screened activity series for the pr…

Screened activity expansion for the pressure of a quantum multi-component plasma and consistency with the local charge neutrality
A. Alastuey, V. Ballenegger, D. Wendland
We consider a quantum multi-component plasma made of point charged particles interacting via the two-body Coulomb potential. Within the Feynman-Kac path integral representation of…
