Chakrabarti, J and Krishnamurthy, HR and Sood, AK (1994) Density Functional Theory of Laser-Induced Freezing in Colloidal Suspensions. In: Physical Review Letters, 73 (21). pp. 2923-2926.
We reexamine the density functional theory of laser-induced freezing, i.e., the freezing of a colloidal liquid into crystalline order in the presence of an external periodic modulating potential V , with its wave vectors tuned to the ordering wave vector in the liquid phase. We show definitively that the initial first order freezing transition (at small V,) changes to a continuous one (at large V,) via a tricritical point provided the modulation wave vectors are suitably chosen. We also present predictions for the parameter values of the tricritical points for a realistic colloidal system.
