correspondence field

Submicron FeCo magnetic grains with different percents of cobalt were grown in the presence of magnetic field. After omitting the excess ions and oxygen, heat treatment was performed and some samples were oriented in a polymer background in the presence of a magnetic field. The results of SEM, XRD, and magnetic measurements confirm the existence of induced magnetic anisotropy. As the strength...

Given a set of points drawn from an unknown continuous probability distribution, one often wishes to infer the underlying distribution. This distribution can be estimated using a simple scalar field theory. Fluctuations around the estimate are characterized by a robust measure of goodness of fit, analogous to the conventional x2, whose distribution can also be calculated. The resulting method o...

Tachyon Condensation on Orbifolds and McKay Correspondence

2008

Tadashi Takayanagi

In this short note we present a mathematical interpretation of tachyon condensation on (three dimensional) orbifolds within the framework of boundary string field theory (BSFT). We explicitly show that important parts of decay modes in brane-antibrane systems with N = 2 boundary supersymmetry can be interpreted as the McKay correspondence described as complexes. This will give an example of the...
