Interplay between valley-orbit couplings at donor atoms and
... In Fig. 1 b and Fig. 1 c we show the computed energy spectrum for a single donor atom subject to two perpendicular interfaces. This system is of interest since it can serve as a physical model of a Fin-FET single-atom transistor. Of particular interest is the point A, where the donor atom is located ...

Progress In N=2 Field Theory
... The very notion of ``what is a quantum field theory’’ is evolving… It no longer suffices just to know the correlators of all local operators. Extended ``operators’’ or ``defects’’ have been playing an increasingly important role in recent years in quantum field theory. Defects are local disturbances ...

A Short History of the Interaction Between QFT and Topology
... QFT that will do what Atiyah wants, but initially doesn’t succeed. Late 1987: Atiyah visits Witten again at the IAS and keeps after him about the TQFT idea. Witten finally realizes that things work if he uses a “twisted” version of N = 2 supersymmetry. Atiyah then attempted to axiomatize Witten’s me ...

This method does not rely on a matrix representation, but depends on a group theoretical analysis. Thus it is available for more than 5 dimensional theories with any gauge symmetry. As an ...
