Effective Field Theory of Protonium
Hans-Werner Hammer, Akaki Rusetsky
We investigate the level shifts in protonium using the framework of non-relativistic effective field theory (NREFT). Our study is prompted by the PUMA collaboration's plans to prob…
Reply to Comment on "Is a Trineutron Resonance Lower in Energy than a Tetraneutron Resonance?"
S. Gandolfi, H. -W. Hammer, P. Klos +2
We reply to a Comment on our Letter [Phys. Rev. Lett. 118, 232501 (2017), arXiv:1612.01502] by A. Deltuva and R. Lazauskas [Phys. Rev. Lett 123, 069201 (2019), arXiv:1904.00925].
Efimov universality with Coulomb interaction
C. H. Schmickler, H. -W. Hammer, E. Hiyama
The universal properties of charged particles are modified by the presence of a long-range Coulomb interaction. We investigate the modification of Efimov universality as a function…
Quantum Monte Carlo calculations of two neutrons in finite volume
P. Klos, J. E. Lynn, I. Tews +5
Ab initio calculations provide direct access to the properties of pure neutron systems that are challenging to study experimentally. In addition to their importance for fundamental…
