Skyrmions and Hopfions in 3D Frustrated Magnets
Carlos Naya, Daniel Schubring, Mikhail Shifman +1
A model of an inversion-symmetric frustrated spin system is introduced which hosts three-dimensional extensions of magnetic Skyrmions. In the continuum approximation this model red…
The Yukawa interaction in ordinary quantum mechanics
Daniel Schubring
The Yukawa interaction is considered in 0+1 dimensions as a pedagogical example to illustrate quantum field theory methods. From the quantum mechanical point of view the system is…
Lessons from models in one dimension
Daniel Schubring
Various topics related to the model in one spacetime dimension (i.e. ordinary quantum mechanics) are considered. The focus is on a pedagogical presentation of quantum field…
Treating Divergent Perturbation Theory: Lessons from Exactly Solvable 2D Models at Large
Daniel Schubring, Chao-Hsiang Sheu, Mikhail Shifman
We consider the operator product expansion (OPE) of correlation functions in the supersymmetric non-linear sigma model at sub-leading order in the large limit in order t…
