Modeling of molecular nitrogen collisions and dissociation processes for direct simulation Monte Carlo [PDF]

open access: bronzeThe Journal of Chemical Physics, 2014
The Direct Simulation Monte Carlo (DSMC) method typically used for simulating hypersonic Earth re-entry flows requires accurate total collision cross sections and reaction probabilities. However, total cross sections are often determined from extrapolations of relatively low-temperature viscosity data, so their reliability is unknown for the high ...

The structure of PX3 (X=Cl, Br, I) molecular liquids from X-ray diffraction, Molecular Dynamics simulations and Reverse Monte Carlo modeling [PDF]

open access: bronzeThe Journal of Chemical Physics 140, 054504 (2014), 2014
Synchrotron X-ray diffraction measurements have been conducted on liquid phosphorus trichloride, tribromide and triiodide. Molecular Dynamics simulations for these molecular liquids were performed with a dual purpose: (1) to establish whether existing intermolecular potential functions can provide a picture that is consistent with diffraction data; (2)

Multiscale approaches to protein-mediated interactions between membranes—relating microscopic and macroscopic dynamics in radially growing adhesions [PDF]

open access: yesNew Journal of Physics, 2015
Macromolecular complexation leading to coupling of two or more cellular membranes is a crucial step in a number of biological functions of the cell. While other mechanisms may also play a role, adhesion always involves the fluctuations of deformable ...

Quantum Monte Carlo method for models of molecular nanodevices [PDF]

open access: greenPhysical Review B, 2005
We introduce a quantum Monte Carlo technique to calculate exactly at finite temperatures the Green function of a fermionic quantum impurity coupled to a bosonic field. While the algorithm is general, we focus on the single impurity Anderson model coupled to a Holstein phonon as a schematic model for a molecular transistor.

Molecular line radiative transfer in protoplanetary disks: Monte Carlo simulations versus approximate methods [PDF]

open access: yes, 2007
We analyze the line radiative transfer in protoplanetary disks using several approximate methods and a well-tested Accelerated Monte Carlo code. A low-mass flaring disk model with uniform as well as stratified molecular abundances is adopted. Radiative transfer in low and high rotational lines of CO, C18O, HCO+, DCO+, HCN, CS, and H2CO is simulated ...

Monte Carlo study of the molecular organization in model nematic droplets. Field effects [PDF]

open access: greenChemical Physics Letters, 1992
Abstract The Monte Carlo technique is used to investigate the orientational order and the molecular organization of model nematic droplets with radial boundary conditions subject to an external field. The effect of varying field strength on these model systems of polymer dispersed liquid crystals (PDLC) is also investigated.

Modeling and Computer Simulation: Molecular Dynamics and Kinetic Monte Carlo [PDF]

open access: green, 2000
Recent years have witnessed tremendous advances in the realistic multiscale simulation of complex physical phenomena, such as irradiation and aging effects of materials, made possible by the enormous progress achieved in computational physics for calculating reliable, yet tractable interatomic potentials and the vast improvements in computational power
