Universality in fermionic dimer-dimer scattering
@article{Deltuva2017UniversalityIF, title={Universality in fermionic dimer-dimer scattering}, author={A. Deltuva}, journal={Physical Review A}, year={2017}, volume={96} }
Collisions of two fermionic dimers near the unitary limit are studied using exact four-particle equations for transition operators in momentum space. Universal properties of dimer-dimer phase shifts and effective range expansion (ERE) parameters are determined. The inclusion of the fourth-order momentum term in the ERE significantly extends its validity to higher collision energies. The dimer-dimer scattering length and effective range are determined in the unitary limit as well as their…

Few nucleons scattering in pionless effective field theory
- Physics
- 2022
We present a comprehensive theoretical study of low-energy few nucleon scattering for systems with A ≤ 4. To this end, we utilize pionless effective field theory, which we employ at next-to-leading…
Eliminating the wave-function singularity for ultracold atoms by a similarity transformation
- Physics

A hyperbolic singularity in the wave-function of $s$-wave interacting atoms is the root problem for any accurate numerical simulation. Here we apply the transcorrelated method, whereby the…

In multipole-bound anions, the excess electron is attached by a short-range multipole potential of a neutral molecule. Such anions are prototypical marginally bound open quantum systems. In…
Tetraneutron resonance in the presence of a dineutron

Background: Several previous studies provided contradicting results for the four-neutron system, some claiming the existence of a 0+ near-threshold resonance, others denying presence of any…
Effective interactions between nuclear clusters
