Dark Matter from Early Decays

open access: yes, 2005
Two leading dark matter candidates from supersymmetry and other theories of physics beyond the standard model are WIMPs and weak scale gravitinos. If the lightest stable particle is a gravitino, then a WIMP will decay into it with a natural lifetime of ...

A perspective on using experiment and theory to identify design principles in dye-sensitized solar cells [PDF]

open access: yes, 2018
Dye-sensitized solar cells (DSCs) have been the subject of wide-ranging studies for many years because of their potential for large-scale manufacturing using roll-to-roll processing allied to their use of earth abundant raw materials.

A joint time-dependent density-functional theory for excited states of electronic systems in solution

open access: yes, 2011
We present a novel joint time-dependent density-functional theory for the description of solute-solvent systems in time-dependent external potentials.

Kaon-Nucleon Scattering Amplitudes and Z$^*$-Enhancements from Quark Born Diagrams [PDF]

open access: yes, 1992
We derive closed form kaon-nucleon scattering amplitudes using the ``quark Born diagram" formalism, which describes the scattering as a single interaction (here the OGE spin-spin term) followed by quark line rearrangement.

GenEvA (II): A phase space generator from a reweighted parton shower [PDF]

open access: yes, 2008
We introduce a new efficient algorithm for phase space generation. A parton shower is used to distribute events across all of multiplicity, flavor, and phase space, and these events can then be reweighted to any desired analytic distribution.

What can we learn from Dijet suppression at RHIC?

open access: yes, 2012
We present a systematic study of the dijet suppression at RHIC using the VNI/BMS parton cascade. We examine the modification of the dijet asymmetry A_j and the within-cone transverse energy distribution (jet-shape) along with partonic fragmentation ...

Soft Modes, Resonances and Quantum Transport [PDF]

open access: yes, 2000
Effects of the propagation of particles, which have a finite life-time and an according width in their mass spectrum, are discussed in the context of transport description.

The OpenMOC method of characteristics neutral particle transport code [PDF]

open access: yes, 2013
The method of characteristics (MOC) is a numerical integration technique for partial differential equations, and has seen widespread use for reactor physics lattice calculations.

Diffusion-Based Coarse Graining in Hybrid Continuum-Discrete Solvers: Theoretical Formulation and A Priori Tests [PDF]

open access: yes, 2015
Coarse graining is an important ingredient in many multi-scale continuum-discrete solvers such as CFD--DEM (computational fluid dynamics--discrete element method) solvers for dense particle-laden flows.

A coupled thermal and electrochemical study of lithium-ion battery cooled by paraffin/porous-graphite-matrix composite [PDF]

open access: yes, 2016
Lithium-ion (Li-ion) battery cooling using a phase change material (PCM)/compressed expanded natural graphite (CENG) composite is investigated, for a cylindrical battery cell and for a battery module scale.
