Analytic nuclear forces and molecular properties from full configuration interaction quantum Monte Carlo
Unbiased stochastic sampling of the one- and two-body reduced density
matrices is achieved in full configuration interaction quantum Monte Carlo with
the introduction of a second, "replica" ensemble of walkers, whose population
evolves in imaginary time independently from the first, and which entails only
modest additional computational overheads. The matrices obtained from this
approach are shown to be representative of full configuration-interaction
quality, and hence provide a realistic opportunity to achieve high-quality
results for a range of properties whose operators do not necessarily commute
with the hamiltonian. A density-matrix formulated quasi-variational energy
estimator having been already proposed and investigated, the present work
extends the scope of the theory to take in studies of analytic nuclear forces,
molecular dipole moments and polarisabilities, with extensive comparison to
exact results where possible. These new results confirm the suitability of the
sampling technique and, where sufficiently large basis sets are available,
achieve close agreement with experimental values, expanding the scope of the
method to new areas of investigation.Comment: 11 page
The Consortium Standard and Patent Pools
We examine patent pools in the context of a consortium standard. Although such pools of complementary technologies are approved by antitrust authorities, the actual implementation has proved to be problematic. We identify two possible obstacles: free riding and bargaining failure. We also examine the traditional RAND(reasonable and non-discriminatory)licensingcondition. We suggest formation, licensing and rent distribution methods more conducive to a successful patent pool operation.

Diffusion of shared goods in consumer coalitions. An agent-based model
This paper focuses on the process of coalition formation conditioning the common decision to adopt a shared good, which cannot be afforded by an average single consumer and whose use cannot be exhausted by any single consumer. An agent based model is developed to study the interplay between these two processes: coalition formation and diffusion of shared goods. Coalition formation is modelled in an evolutionary game theoretic setting, while adoption uses elements from both the Bass and the threshold models. Coalitions formation sets the conditions for adoption, while diffusion influences the consequent formation of coalitions. Results show that both coalitions and diffusion are subject to network effects and have an impact on the information flow though the population of consumers. Large coalitions are preferred over small ones since individual cost is lower, although it increases if higher quantities are purchased collectively. The paper concludes by connecting the model conceptualisation to the on-going discussion of diffusion of sustainable goods, discussing related policy implications
