Two-dimensional colloidal structures responsive to external fields
Introduction Well-characterized and extremely monodisperse colloidal particles have become model systems for various problems in statistical physics such as phase transitions or self-organization of colloids. The use of colloidal particles bears twO considerable advantages compared with atomic systems. First. the size of the particles in the micron range allows direct visualization by light mic...
متن کاملFluctuation-induced order in two-dimensional colloidal clusters
– The behavior of a finite number (N = 29) of paramagnetic colloidal particles in 2D circular hard-wall cavities is investigated. By applying a magnetic field B, the interaction between the particles is varied. We demonstrate that the angular diffusion of the particles which are arranged in shells is highly anisotropic and shows a non-monotonic behavior as a function of B. When reducing radial ...
متن کاملLaser-induced reentrant freezing in two-dimensional attractive colloidal systems.
The effects of an externally applied one-dimensional periodic potential on the freezing and melting behavior of two-dimensional systems of colloidal particles with a short-range attractive interaction are studied using Monte Carlo simulations. In such systems, incommensuration results when the periodicity of the external potential does not match the length scale at which the minimum of the attr...
متن کاملTwo-Dimensional Seven-State Potts Model Under External Magnetic Field
The two-dimensional Potts Model with seven states under external field is studied using a cluster algorithm. Cluster size distribution and the fluctuations in the average cluster size provide helpful information on the order of phase transitions. Potts model [1] is known to have a very rich critical behaviour and considered as a testing ground for both analytical and numerical methods. Recently...
متن کاملQuantum Corrections to the Two Dimensional Gravity with External Field
We introduce an external field to calculate the quantum corrections to the solutions of the 2d gravity, via trace anomaly. We show that there are black hole type solutions even in the absence of matter field and cosmological constant. We also see that these solutions are similar to the ones obtained from dilaton two dimensional gravity. PACS: 04.60.+n; 11.17.+y; 97.60.Lf e-mail: [email protected]...
