Thermodynamic Properties of the Discommensuration Point for Incommensurate Structures: A "Third-Order" Phase Transition
A. N. Rubtsov, T. Janssen
The consequences of the opening of a phason gap in incommensurate systems are studied on a simple model, the discrete frustrated -model. Analytical considerations and numerica…

Quantum discrete model at finite temperatures: the mean-field phase diagram
V. V. Savkin, A. N. Rubtsov
The quantum discrete model at finite temperature is studied in the mean-field approximation. The phase diagrams are obtained for a wide range of the model parameters. The dom…

Analytical model for a crossover between uncorrelated and fractal behaviour of a self-repulsive chain
A. N. Rubtsov
The thermodynamics of a long self-repulsive chain is studied. In dimensions it shows two distinctly different regimes, corresponding to weak and strong correlations in the sy…
