Two Cold Atoms in a Time-Dependent Harmonic Trap in One Dimension
M. Ebert, A. Volosniev, H. -W. Hammer
We analyze the dynamics of two atoms with a short-ranged pair interaction in a one-dimensional harmonic trap with time-dependent frequency. Our analysis is focused on two represent…
Effective Theory of 3H and 3He
Sebastian König, Harald W. Grießhammer, H. -W. Hammer +1
We present a new perturbative expansion for pionless effective field theory with Coulomb interactions in which at leading order the spin-singlet nucleon-nucleon channels are taken…
Range corrections in Proton Halo Nuclei
Emil Ryberg, Christian Forssén, H. -W. Hammer +1
We analyze the effects of finite-range corrections in halo effective field theory for S-wave proton halo nuclei. We calculate the charge radius to next-to-leading order and the ast…
Simulation of Time-dependent Heisenberg Models in 1D
A. G. Volosniev, H. -W. Hammer, N. T. Zinner
In this paper, we provide a theoretical analysis of strongly interacting quantum systems confined by a time-dependent external potential in one spatial dimension. We show that such…
New structures in the proton-antiproton system
I. T. Lorenz, H. -W. Hammer, U. -G. Meißner
In the most recent measurements of the reaction by the BABAR collaboration, new structures have been found with unknown origin. We examine a possible…
Limit Cycles from the Similarity Renormalization Group
P. Niemann, H. -W. Hammer
We investigate renormalization group limit cycles within the similarity renormalization group (SRG) and discuss their signatures in the evolved interaction. A quantitative method t…
