Study of electron-positron annihilation into four pions within chiral effective field theory in the low energy region
Jia-Yu Zhou, Hao-Xiang Pan, Ling-Yun Dai
In this paper, we employ chiral effective field theory to study the process of electron-positron annihilation into four pions in the low energy region within GeV…

Band modulations and topological transitions in a one-dimensional periodic bead-on-string chain
Haocong Pan, Wei Wang, Chunling Liu
We study band modulations and topological transitions in a one-dimensional periodic bead-on-string chain. Using an exact transfer-matrix formulation of the wave equation with perio…

Leggett's bound and superfluidity in strongly interacting bosons
Lorenzo Pizzino, Haocong Pan, Thierry Giamarchi +1
A density-based superfluid bound called Leggett's bound has been proved to be a good estimator of the superfluid fraction for cold atomic gases in the mean-field regime. Here, we i…
