Dr. Ke Qiao, assistant research scientist for the Center for Astrophysics, Space Physics and Engineering Research (CASPER) at Baylor University, will present a colloquium, "Wave Modes, Instabilities and Phase Transitions in Plasma Crystals and Dust Clusters in Dusty Plasmas," at 4 p.m. Wednesday, Jan. 25, in room E125 of the Baylor Sciences Building on the Baylor campus.

Presented as a part of the Baylordepartment of physics' 2012 Spring Physics Colloquium Series, Qiao will discuss research using numerical simulations on dust lattice waves (DLWs) in two dimensional (2D) plasma crystals and normal modes in 2D dust clusters. He also will propose that a special kind of instability unique to dusty plasmas, induced by the ion wakefield around dusts, is the cause of experimentally observed melting.
