Micromagnetic simulations of clusters of nanoparticles with internal structure: Application to magnetic hyperthermia
Razyeh Behbahani, Martin L. Plumer, Ivan Saika-Voivod
Micromagnetic simulation results on dynamic hysteresis loops of clusters of iron oxide nanoparticles (NPs) with internal structure composed of nanorods are compared with the widely…
Coarse-graining in micromagnetic simulations of dynamic hysteresis loops
Razyeh Behbahani, Martin L. Plumer, Ivan Saika-Voivod
Micromagnetic simulations based on the stochastic Landau-Lifshitz-Gilbert equation are used to calculate dynamic magnetic hysteresis loops relevant to magnetic hyperthermia. With t…
Continuous degeneracy of the fcc kagome lattice with magnetic dipolar interactions
Andrew R. Way, Kyle P. W. Hall, Ivan Saika-Voivod +2
Results are presented on analytic and computational analyses of the spin states associated with a 3D fcc lattice composed of ABC stacked kagome planes of magnetic ions with only lo…
Monte Carlo simulations of the kagome lattice with magnetic dipolar interactions
M. S. Holden, M. L. Plumer, I. Saika-Voivod +1
The results of extensive Monte Carlo simulations of classical spins on the two-dimensional kagome lattice with only dipolar interactions are presented. In addition to revealing the…
Crystallization of Lennard-Jones nanodroplets: from near melting to deeply supercooled
Shahrazad M. A. Malek, Gregory P. Morrow, Ivan Saika-Voivod
We carry out molecular dynamics (MD) and Monte Carlo (MC) simulations to characterize nucleation in liquid clusters of 600 Lennard-Jones particles over a broad range of temperature…
Inverse melting in a two-dimensional off-lattice model
Ahmad M. Almudallal, Sergey V. Buldyrev, Ivan Saika-Voivod
We carry out computer simulations of a simple, two-dimensional off-lattice model that exhibits inverse melting. The monodisperse system comprises core-softened disks interacting th…
Crystal Nucleation in a Supercooled Liquid with Glassy Dynamics
Ivan Saika-Voivod, Richard K. Bowles, Peter H. Poole
In simulations of supercooled, high-density liquid silica we study a range of temperature T in which we find both crystal nucleation, as well as the characteristic dynamics of a gl…
Phase diagram of silica from computer simulation
Ivan Saika-Voivod, Francesco Sciortino, Tor Grande +1
We evaluate the phase diagram of the ``BKS'' potential [Van Beest, Kramer and van Santen, Phys. Rev. Lett. 64, 1955 (1990)], a model of silica widely used in molecular dynamics (MD…
Free energy and configurational entropy of liquid silica: fragile-to-strong crossover and polyamorphism
Ivan Saika-Voivod, Francesco Sciortino, Peter H. Poole
Recent molecular dynamics (MD) simulations of liquid silica, using the ``BKS'' model [Van Beest, Kramer and van Santen, Phys. Rev. Lett. {\bf 64}, 1955 (1990)], have demonstrated t…
Fragile-to-strong transition and polyamorphism in the energy landscape of liquid silica
Ivan Saika-Voivod, Peter H. Poole, Francesco Sciortino
We study the static and dynamic properties of liquid silica over a wide range of temperature T and density using computer simulations. The results reveal a change in the potential…
