We study a U (1) × U (1) system in (2+ 1) dimensions with long-range interactions and mutual statistics. The model has the same form after the application of operations from the modular group, a property which we call modular invariance. Using the modular invariance of the model, we propose a possible phase diagram. We obtain a sign-free reformulation of the model and study it in Monte Carlo. T...

The analytical zero-temperature phase diagram of the double exchange model for classical background spins as a function of the carrier density and Hund’s coupling in the entire range of these parameters is presented. By constructing a continuum field theory we explore the possibility of a continuous phase transition from ferromagnetic state to a gently varying textured state. We find such a tra...

the present work was aimed to design and develop self-nanoemulsifying drug delivery systems (snedds) with the objective to overcome the problems associated with the delivery of talinolol, a hydrophobic and poorly bioavailable drugs having ph dependant solubility. the solubility of talinolol in various oils, surfactants, cosurfactants and aqueous phases were determined to identify and select the...

It has been stated that the inverse filtering of room transfer functions is possible using multiple inputs under certain conditions [1]. In this paper we address these conditions from a numerical perspective. A method is developed to determine the numerical precision of multiple input inverse filtering techniques. This method is applied to two simulated rooms, and the numerical precision is est...

We propose a modification of the Kuramoto model to account for the effective change in the coupling constant among the oscillators, as suggested by some experiments on Josephson junction, laser arrays, and mechanical systems, where the active elements are turned on one by one. The resulting model is analytically tractable and predicts that both first and second order phase transitions are possi...

Percolation is one of the most studied processes in statistical physics. A recent paper by Achlioptas [Science 323, 1453 (2009)] showed that the percolation transition, which is usually continuous, becomes discontinuous ("explosive") if links are added to the system according to special cooperative rules (Achlioptas processes). In this paper, we present a detailed numerical analysis of Achliopt...
