DESCRIPTION:Speakers: Da Liu (Shandong University)\nIn this talk\, I will 
 discuss about my recent work on the searches for the ultralight scalar dar
 k matter with quadratic interactions with SM fields. This will lead to the
  effective interactions between the ultralight dark matter and the nucleon
  fields phi^2 N N/f below the QCD confinement scale\, which can be thought
  as potential barrier for the dark matter wind in the presence of ordinary
  matter. When the potential barrier is large enough compared with the kine
 tic energy of the dark matter\, the dark matter flux will bounce back from
  the ordinary object\, as a result inducing a pressure force on the object
 . After taking into the constraints from Supernova cooling\, BBN and gravi
 tational inverse square law test\, there exists parameter spaces in our mo
 del which can be searched for by utilizing this force effect on the experi
 ment for the test of the weak equivalence principle.\n\nhttps://indico.itp
