Why shape matters in granular compaction
Anita Mehta, J. M. Luck
We present a stochastic model of dynamically interacting grains in one dimension, in the presence of a low vibrational intensity, to investigate the effect of shape on the statics…
Phase Transitions of Soft Disks in External Periodic Potentials: A Monte Carlo Study
W. Strepp, S. Sengupta, P. Nielaba
The nature of freezing and melting transitions for a system of model colloids interacting by a DLVO potential in a spatially periodic external potential is studied using extensive…
Study of a pair of coupled continuum equations modeling surface growth
Ain-ul Huda, Omjyoti Dutta, Abhijit Mookerjee
In this communication we introduce a pair of coupled continuum equations to model overlayer growth with evaporation-accretion due to thermal or mechanical agitations of the substra…
Quasistatic Scale-free Networks
G. Mukherjee, S. S. Manna
A network is formed using the sites of an one-dimensional lattice in the shape of a ring as nodes and each node with the initial degree . links are then introduce…
Self-organized random walks and stochastic sandpile: From linear to branched avalanches
S. S. Manna, A. L. Stella
In a model of self-organized criticality unstable sites discharge to just one of their neighbors. For constant discharge ratio and for a certain range of values of the input en…
Modulated Scale-free Network in the Euclidean Space
S. S. Manna, Parongama Sen
A random network is grown by introducing at unit rate randomly selected nodes on the Euclidean space. A node is randomly connected to its -th predecessor of degree with a…
