Gauging in superconductors and other electronic systems
Marcus Berg, Andrea Cappelli, Riccardo Villa
Ordinary, s-wave superconductors have been recognized as being topological phases of matter, in which the dynamical gauge field implies less understood global features. Using the t…
One-loop Amplitudes: String Methods, Infrared Regularization, and Automation
Marcus Berg, Michael Haack, Yonatan Zimmerman
We calculate field theory loop amplitudes by string methods, applied to half-maximal 4-point one-loop graviton amplitudes. Infrared divergences are regulated similarly to soft-coll…
Brane/Flux Interactions in Orientifolds
Marcus Berg, Michael Haack, Boris Kors
Combining the benefits of D-branes and background fluxes in string compactifications opens up the possibility to explore phenomenologically interesting brane world models with stab…
Effective Action of Matter Fields in Four-Dimensional String Orientifolds
P. Bain, M. Berg
We study various aspects of the Kahler metric for matter fields in N=1,2 orientifold compactifications of type IIB string theory. The result has an infrared-divergent part which re…
