Non-relativistic bound states in a finite volume
Sebastian König, Dean Lee, H. -W. Hammer
We derive general results for the mass shift of bound states with angular momentum l >= 1 in a periodic cubic box in two and three spatial dimensions. Our results have applications…
Topological phases for bound states moving in a finite volume
Shahin Bour, Sebastian König, Dean Lee +2
We show that bound states moving in a finite periodic volume have an energy correction which is topological in origin and universal in character. The topological volume corrections…
On the Efimov Effect in Higher Partial Waves
K. Helfrich, H. -W. Hammer
Using the framework of effective field theory, we present a detailed study of the Efimov effect in higher partial waves for systems of two identical particles and a third distingui…
Strong interactions: From methods to structures
Nora Brambilla, Evgeny Epelbaum, H. -W. Hammer +1
These are the proceedings of the workshop on "Strong interactions: From methods to structures" held at the Physikzentrum Bad Honnef of the Deutsche Physikalische Gesellschaft, Bad…
Volume Dependence of Bound States with Angular Momentum
Sebastian König, Dean Lee, H. -W. Hammer
We derive general results for the mass shift of bound states with angular momentum l >= 1 in a finite periodic volume. Our results have direct applications to lattice simulations o…
Neutral pion photoproduction off 3H and 3He in chiral perturbation theory
Mark Lenkewitz, Evgeny Epelbaum, H. -W. Hammer +1
We calculate electromagnetic neutral pion production off three-nucleon bound states (3H, 3He) at threshold to leading one-loop order in the framework of chiral nuclear effective fi…
