Microstructural Percolation
Microstructural Percolation
<
2010/11/18
The macroscopic mechanical properties of colloidal particle gels strongly depend on
the local arrangement of the powder particles. Experiments have shown that more
heterogeneous microstructures exhi...
The abelian hierarchy of quantum Hall states accounts for most of the states in the
lowest Landau level, and there is evidence of a similar hierarchy of non-abelian states
emanating from the ν = 5/2...
Mass-Transport Models with Fragmentation and Aggregation

<
2010/11/22
We present a review of nonequilibrium phase transitions in mass-transport models with kinetic processes like fragmentation, diffusion, aggregation, etc. These models have been used extensively to stud...

2010/11/18
Using lattice models we explore the factors that determine the tendencies of polypeptide chains
to aggregate by exhaustively sampling the sequence and conformational space. The morphologies of the b...

2010/10/21
We show how the momentum distribution of gaseous Bose–Einstein condensates can be shaped
by applying a sequence of standing–wave laser pulses. We present a theory of the effect of such a pulse sequen...
