The Kagome Antiferromagnet: A Schwinger-Boson Mean-Field Theory Study

open access: yes, 2007
The Heisenberg antiferromagnet on the Kagom\'{e} lattice is studied in the framework of Schwinger-boson mean-field theory. Two solutions with different symmetries are presented.

Combined thermal and particle shape effects on powder spreading in additive manufacturing via discrete element simulations [PDF]

open access: yesarXiv
The thermal and mechanical behaviors of powders are important for various additive manufacturing technologies. For powder bed fusion, capturing the temperature profile and the packing structure of the powders prior to melting is challenging due to both the various pathways of heat transfer and the complicated properties of powder system.

Recent developments in the economics of price discrimination [PDF]

open access: yes, 2006
This paper selectively surveys the recent literature on price discrimination. The focus is on three aspects of pricing decisions: the information about customers available to firms; the instruments firms can use in the design of their tariffs; and the ...

FibreChain: characterization and modeling of thermoplastic composites processing [PDF]

open access: yes, 2013
Thermoplastic composites feature the advantage of melting and shaping. The material properties during processing and the final product properties are to a large extent determined by the thermal history of the material.
