Effective Field Theory for Cold Atoms
H. -W. Hammer
Effective Field Theory (EFT) provides a powerful framework that exploits a separation of scales in physical systems to perform systematically improvable, model-independent calculat…
Universality in Few-body Systems with Large Scattering Length
Eric Braaten, H. -W. Hammer
Particles with short-range interactions and a large scattering length have universal low-energy properties that do not depend on the details of their structure or their interaction…
Modern theory of nuclear forces
Ulf-G. Meißner
Nuclear forces can be systematically derived using effective chiral Lagrangians consistent with the symmetries of QCD. I review the status of the calculations for two- and three-nu…
On the correlation between the binding energies of the triton and the alpha-particle
L. Platter, H. -W. Hammer, U. -G. Meißner
We consider the correlation between the binding energies of the triton and the alpha-particle which is empirically observed in calculations employing different phenomenological nuc…
Universal Properties of the Four-Boson System in Two Dimensions
L. Platter, H. -W. Hammer, U. -G. Meißner
We consider the nonrelativistic four-boson system in two dimensions interacting via a short-range attractive potential. For a weakly attractive potential with one shallow two-body…
Universal Properties of Two-Dimensional Boson Droplets
H. -W. Hammer, D. T. Son
We consider a system of N nonrelativistic bosons in two dimensions, interacting weakly via a short-range attractive potential. We show that for N large, but below some critical val…
The Four-Boson System with Short-Range Interactions
L. Platter, H. -W. Hammer, Ulf-G. Meißner
We consider the non-relativistic four-boson system with short-range forces and large scattering length in an effective quantum mechanics approach. We construct the effective intera…
