Tricritical behavior in deterministic aperiodic ising systems
We use a mixed-spin model, with aperiodic ferromagnetic exchange interactions and crystalline fields, to investigate the effects of deterministic geometric fluctuations on first-order transitions and tricritical phenomena. The interactions and the crystal-field parameters are distributed according to some two-letter substitution rules. From a Migdal-Kadanoff real-space renormalization-group cal...
متن کاملTricritical behavior of two-dimensional scalar field theories.
We compute by Monte Carlo numerical simulations the critical exponents of two-dimensional scalar eld theories at the 6 tricritical point. The results are in agreement with the Zamolodchikov conjecture based on conformal invariance. 1 In the last decade there has been a considerable progress in the classiication of uni-versality classes of two-dimensional (2D) critical phenomena in terms of conf...
متن کاملAggregation behavior of long-chain piperidinium ionic liquids in ethylammonium nitrate.
Micelles formed by the long-chain piperidinium ionic liquids (ILs) N-alkyl-N-methylpiperidinium bromide of general formula CnPDB (n = 12, 14, 16) in ethylammonium nitrate (EAN) were investigated through surface tension and dissipative particle dynamics (DPD) simulations. Through surface tension measurements, the critical micelle concentration (cmc), the effectiveness of surface tension reductio...
متن کاملHeat capacity behavior in the critical region of the ionic binary mixture ethylammonium nitrate-n-octanol
At temperatures between 30 degrees C and 58 degrees C we have recorded the heat capacity of the ionic ethylammonium nitrate-n-octanol mixture of critical composition and also of the constituents. Different samples of the binary mixture have been measured with its upper critical demixing temperature T(c) varying between 41.04 degrees C and 46.87 degrees C, depending on small traces of water with...
متن کاملMultiple critical behavior of probabilistic limit theorems in the neighborhood of a tricritical point
We derive probabilistic limit theorems that reveal the intricate structure of the phase transitions in a mean-field version of the Blume-Emery-Griffiths model [4]. These probabilistic limit theorems consist of scaling limits for the total spin and moderate deviation principles (MDPs) for the total spin. The model under study is defined by a probability distribution that depends on the parameter...
