One-dimensional Dexter-type excitonic topological phase transition
Jianhua Zhu, Ji Chen, Wei Wu
Recently topogical excitons have attracted much attention. However, studies on the topological properties of excitons in one dimension are still rare. Here we have computed the Zak…
Co-existence of charge density wave and anti-ferromagnetic coupling in the spin-chain compound BaCrS
Jianhua Zhu, Jianfeng Zhang, Yilin Zhang +6
Here we have performed detailed first principles calculations for the electronic structure and magnetic properties of BaCrS to study the origin of the anti-ferromagn…
Momentum-space probability density of He in Halo Effective Field Theory
M. Göbel, H. -W. Hammer, C. Ji +1
We compute the momentum-space probability density of He at leading order in Halo EFT. In this framework, the He nucleus is treated as a three-body problem with a …
Effective field theory description of halo nuclei
H. -W. Hammer, C. Ji, D. R. Phillips
Nuclear halos emerge as new degrees of freedom near the neutron and proton driplines. They consist of a core and one or a few nucleons which spend most of their time in the classic…
An effective-field-theory analysis of Efimov physics in heteronuclear mixtures of ultracold atomic gases
Bijaya Acharya, Chen Ji, Lucas Platter
We use an effective-field-theory framework to analyze the Efimov effect in heteronuclear three-body systems consisting of two species of atoms with a large interspecies scattering…
Universal Relations for Range Corrections to Efimov Features
Chen Ji, Eric Braaten, Daniel R. Phillips +1
In a three-body system of identical bosons interacting through a large S-wave scattering length , there are several sets of Efimov features related by discrete scale invariance.…
