# s -wave contacts of quantum gases in quasi-one-dimensional and quasi-two-dimensional traps

@article{He2019sC, title={s -wave contacts of quantum gases in quasi-one-dimensional and quasi-two-dimensional traps}, author={Min He and Qi Zhou}, journal={Physical Review A}, year={2019} }

In quasi-one- or quasi-two-dimensional traps with strong transverse confinements, quantum gases behave like strictly one- or two-dimensional systems at large length scales. However, at short distance, the two-body scattering intrinsically has three-dimensional characteristics such that an exact description of any universal thermodynamic relation requires three-dimensional contacts, no matter how strong the confinement is. A fundamental question arises as to whether one- or two-dimensional…
