T-branes and defects
Fernando Marchesano, Raffaele Savelli, Sebastian Schwieger
We study T-branes on compact Kaehler surfaces, in the presence of fields localised at curves. If such fields are treated as defects, their vevs induce delta-function sources for th…
Compact T-branes
Fernando Marchesano, Raffaele Savelli, Sebastian Schwieger
We analyse global aspects of 7-brane backgrounds with a non-commuting profile for their worldvolume scalars, also known as T-branes. In particular, we consider configurations with…
T-branes and -corrections
Fernando Marchesano, Sebastian Schwieger
We study -corrections in multiple D7-brane configurations with non-commuting profiles for their transverse position fields. We focus on T-brane systems, crucial in F-theory GUT…
On and F-Theory GUTs
Florent Baume, Eran Palti, Sebastian Schwieger
We study correlations between the massless field spectra of F-theory fibrations supporting an gauge symmetry extended by Abelian symmetries and the spectra that arise from…
Green function theory versus Quantum Monte Carlo calculations for thin magnetic films
S. Henning, F. Koermann, J. Kienert +2
In this work we compare numerically exact Quantum Monte Carlo (QMC) calculations and Green function theory (GFT) calculations of thin ferromagnetic films including second order ani…
Spin wave excitations: The main source of the temperature dependence of Interlayer exchange coupling in nanostructures
S. Schwieger, J. Kienert, K. Lenz +3
Quantum mechanical calculations based on an extended Heisenberg model are compared with ferromagnetic resonance (FMR) experiments on prototype trilayer systems Ni_7/Cu_n/Co_2/Cu(00…
