Accelerating off-lattice kinetic Monte Carlo simulations to predict hydrogen vacancy-cluster interactions in -Fe
C. J. Williams, E. I. Galindo-Nava
We present an enhanced off-lattice kinetic Monte Carlo (OLKMC) model, based on a new method for tolerant classification of atomistic local-environments that is invariant under Eucl…
Momentum distribution and ordering in mixtures of ultracold light and heavy fermionic atoms
M. M. Maska, R. Lemanski, C. J. Williams +1
The momentum distribution is one of the most important quantities which provides information about interactions in many-body systems. At the same time it is a quantity that can eas…
Efficiency for preforming molecules from mixtures of light Fermi and heavy Bose atoms in optical lattices: the strong-coupling-expansion method
Anzi Hu, J. K. Freericks, M. M. Maśka +1
We discuss the application of a strong-coupling expansion (perturbation theory in the hopping) for studying light-Fermi-heavy-Bose (like K-Rb) mixtures in optical lat…
Hexatic, Wigner Crystal, and Superfluid Phases of Dipolar Bosons
Kaushik Mitra, C. J. Williams, C. A. R. Sá de Melo
The finite temperature phase diagram of two-dimensional dipolar bosons versus dipolar interaction strength is discussed. We identify the stable phases as dipolar superfluid (DSF),…
Trapped fermion mixtures with unequal masses: a Bogoliubov-de Gennes approach
M. Iskin, C. J. Williams
We use the Bogoliubov-de Gennes formalism to analyze the ground state phases of harmonically trapped two-species fermion mixtures with unequal masses. In the weakly attracting limi…
Pattern formation in mixtures of ultracold atoms in optical lattices
M. M. Maska, R. Lemanski, J. K. Freericks +1
Regular pattern formation is ubiquitous in nature; it occurs in biological, physical, and materials science systems. Here we propose a set of experiments with ultracold atoms that…
