So imagine that we gradually but steadily reduce the intensity to the point where we are considering the process photon by photon. ...

Instead of the single point separating the antiferromagnet from the normal metal, we have discovered a broad region between these two phases where the magnetic order is destroyed but certain areas of the Fermi surface are closed by a large gap. This gap r ...

An Extreme form of Superactivation for Quantum Zero-Error
... In order to prove our results, we need some basic notions from algebraic geometry (see e.g. Ref. [7]). A key concept is that of a Zariski-closed set, and the resulting Zariski topology. We will only ever work over base fields C or R, so for our purposes Zariski-closed sets are sets defined by a coll ...

Since the effective quantum potential from Proposition 2.1 depends on both the x- and p-spaces, an FMM algorithm for three-dimensional structures works in a six-dimensional space. Although FMM algorithms work in ...
