DESCRIPTION:Speaker: Jinglun Li\nhosted by Mikhail Lemeshko\nAbstract: The 
 three-body scattering is crucial for ultracold trapped atomic gases as its
  inelastic process usually dominates the loss of atoms while its elastic p
 rocess can stabilize the system against the collapse to form liquid quantu
 m droplets when the interatomic interaction is attractive. The three-body 
 scattering in these quantum gases provides also a unique opportunity to un
 derstand a variety of universalities in few-body physics\, such as the Efi
 mov effect\, thanks to the high tunability of interatomic interactions. In
  ultracold atomic gases\, the most relevant three-body inelastic scatterin
 g process is three free atoms colliding to form a molecule and releasing t
 he binding energy into the translational movement of the molecule and thir
 d atom\, the so-called three-body recombination (TBR). As an elementary ch
 emical reaction process\, understanding TBR is of fundamental importance f
 or various fields of basic science such as astrophysics\, atmospheric phys
 ics and physical chemistry. This talk will discuss our recent studies on u
 ltracold three-body scattering problems using two sophisticated numerical 
 techniques and the applications to Efimov resonances\, properties of quant
 um gases and fundamental principles in chemical reactions.
