Electronic stress tensor analysis of hydrogenated palladium clusters
Kazuhide Ichikawa, Ayumu Wagatsuma, Pawel Szarek +3
We study the chemical bonds of small palladium clusters Pd_n (n=2-9) saturated by hydrogen atoms using electronic stress tensor. Our calculation includes bond orders which are rece…
Optimal Modification Factor and Convergence of the Wang-Landau Algorithm
Chenggang Zhou, Jia Su
We propose a strategy to achieve the fastest convergence in the Wang-Landau algorithm with varying modification factors. With this strategy, the convergence of a simulation is at l…
Spectral weight transfer in a disorder-broadened Landau level
Chenggang Zhou, Mona Berciu
In the absence of disorder, the degeneracy of a Landau level (LL) is , where is the magnetic field, is the area of the sample and is the magnetic flux q…
Monte Carlo simulations of , a classical Heisenberg antiferromagnet in two-dimensions with dipolar interaction
Chenggang Zhou, D. P. Landau, T. C. Schulthess
We study the phase diagram of a quasi-two dimensional magnetic system with Monte Carlo simulations of a classical Heisenberg spin Hamiltonian which includes the d…
Hidden zero-temperature bicritical point in the two-dimensional anisotropic Heisenberg model: Monte Carlo simulations and proper finite-size scaling
Chenggang Zhou, D. P. Landau, Thomas C. Schulthess
By considering the appropriate finite-size effect, we explain the connection between Monte Carlo simulations of two-dimensional anisotropic Heisenberg antiferromagnet in a field an…
Monte Carlo simulations of Nanoparticles
Chenggang Zhou, T. C. Schulthess, D. P. Landau
We use Monte Carlo simulations to study nanoparticles. Finite size and surface effects differentiate them from their bulk counterparts. A continuous version of t…
