Freedericksz Transition in Nematic Liquid Crystal Flows in Dimension Two
Soojung Kim(Korea Advanced Institute of Science and Technology)
Thursday, January 11, 2018 - 15:00 to 16:00  Room 264, Geography Building, 3663 Zhongshan Road North, Shanghai

Below is a Math PDE seminar scheduled on January 11 , sponsored by NYU-ECNU Institute of Mathematical Sciences at NYU Shanghai.All are welcome and light refreshments will be served!

Abstract:
In this talk, we study a dynamical instability of liquid crystals induced by applied magnetic fields, which is the so-called Freedericksz transition. More precisely, we show that if the magnetic field strength exceeds the threshold, any global solution to the simplified Ericksen-Leslie system subject to the magnetic field converges exponentially to a unique nontrivial equilibrium. Here we imposed certain initial and strong anchoring boundary conditions. It is also proved that below the threshold, the equilibrium of the orientation angle is the zero state. This is based on joint work with Yuan Chen and Yong Yu.
