Monte Carlo approach for studying microphases applied to the axial next-nearest-neighbor Ising and the Ising-Coulomb models
(Physical Review B - Condensed Matter and Materials Physics, 2011-06-09)
The equilibrium phase behavior of microphase-forming systems is notoriously difficult to obtain because of the extended metastability of their modulated phases. In this paper we present a systematic simulation methodology ...
Erratum: [N]pT ensemble and finite-size-scaling study of the critical isostructural transition in the generalized exponential model of index 4
(Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2012-12-05)
(Arch Biochem Biophys, 2016-07-15)
Crystallization is a key step in macromolecular structure determination by crystallography. While a robust theoretical treatment of the process is available, due to the complexity of the system, the experimental process ...
Reentrant and isostructural transitions in a cluster-crystal former.
(Phys Rev Lett, 2010-12-10)
We study the low-temperature behavior of a simple cluster-crystal forming system through simulation. We find the phase diagram to be hybrid between the Gaussian core model and the penetrable sphere model. The system additionally ...
Monte carlo study of the axial next-nearest-neighbor Ising model.
(Phys Rev Lett, 2010-05-14)
The equilibrium phase behavior of microphase-forming systems is notoriously difficult to obtain because of the extended metastability of the modulated phases. We develop a simulation method based on free-energy integration ...
Dimensional dependence of the Stokes-Einstein relation and its violation.
(J Chem Phys, 2013-10-28)
We generalize to higher spatial dimensions the Stokes-Einstein relation (SER) as well as the leading correction to diffusivity in finite systems with periodic boundary conditions, and validate these results with numerical ...
Numerical detection of the Gardner transition in a mean-field glass former.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2015-07)
Recent theoretical advances predict the existence, deep into the glass phase, of a novel phase transition, the so-called Gardner transition. This transition is associated with the emergence of a complex free energy landscape ...
Numerical and theoretical study of a monodisperse hard-sphere glass former
(PHYSICAL REVIEW E, 2010-04)
Kinetic Monte Carlo simulations for birefringence relaxation of photo-switchable molecules on a surface.
(J Chem Phys, 2016-03-14)
Recent experiments have demonstrated that in a dense monolayer of photo-switchable dye methyl-red molecules the relaxation of an initial birefringence follows a power-law decay, typical for glass-like dynamics. The slow ...
Phase ordering of zig-zag and bow-shaped hard needles in two dimensions.
(J Chem Phys, 2015-09-21)
We perform extensive Monte Carlo simulations of a two-dimensional bent hard-needle model in both its chiral zig-zag and its achiral bow-shape configurations and present their phase diagrams. We find evidence for a variety ...
