Multiscale Simulations of Soft and Hard Matter
Colloidal suspensions usually consist of colloidal particles of size 1 nm to 1 μm which are surrounded by a solvent, typically water. In these systems the kinetic energy of the colloids at room temperature is about the strength of their interaction energy. Hence, these systems or materials are considered as soft and deformable and known as “soft matter”. Molecular dynamics (MD) simulation of su...
متن کاملClassical density functional theory methods in soft and hard matter.
Herein we provide a brief summary of the background, events and results/outcome of the CECAM workshop 'Classical density functional theory methods in soft and hard matter' held in Lausanne between October 21 and October 23 2009, which brought together two largely separately working communities, both of whom employ classical density functional techniques: the soft-matter community and the theore...
متن کاملHard knowledge, soft values
The paper contrasts two domains of school education, natural science and citizenship education (as a paradigm of “hard” and “soft” subjects), with respect to their epistemological and ethical foundations. A sharp contrast between their associated world-views within the school community is accentuated at the outset. The epistemological shortcomings inherent in both are subsequently explored, and...
متن کاملSoft and Hard Qcd *
I review various theoretical questions that arise from data from HERA and the Tevatron, and which are relevant for the LHC. They range from soft physics, such as the total cross section, to hard physics, such as Higgs production. In particular, I argue that the proton's gluon density is somewhat larger at small x than is currently accepted.
متن کاملSoft and hard pomerons
Regge theory provides an excellent description of small-x structurefunction data from Q = 0 up to the highest available values. The large-Q data should also be described by perturbative QCD: the two descriptions must agree in the region where they overlap. However, at present there is a serious lack in our understanding of how to apply perturbative QCD at small x. The usual lowestorder or next-...
