Cooperativity in sandpiles: statistics of bridge geometries
Anita Mehta, G. C. Barker, J. M. Luck
Bridges form dynamically in granular media as a result of spatiotemporal inhomogeneities. We classify bridges as linear and complex, and analyse their geometrical characteristics.…
Shaken, not stirred: why gravel packs better than bricks
Anita Mehta, J. M. Luck
We explore the effect of shape -- jagged vs. regular -- in the jamming limit of very gently shaken packings. Our measure of shape $\eps$ is the void space occupied by a disordered…
Interacting black holes on the brane: the seeding of binaries
A. S. Majumdar, A. Mehta, J. M. Luck
We consider the evolution of sub-horizon-sized black holes which are formed during the high energy phase of the braneworld scenario. These black holes are long-lived due to modifie…
Non-monotonic disorder-induced enhanced tunneling
J. M. Luck
The quantum-mechanical transmission through a disordered tunnel barrier is investigated analytically in the following regime: (correlation range of the random potential) << (penetr…
Anomalous self-diffusion in the ferromagnetic Ising chain with Kawasaki dynamics
C. Godrèche, J. M. Luck
We investigate the motion of a tagged spin in a ferromagnetic Ising chain evolving under Kawasaki dynamics. At equilibrium, the displacement is Gaussian, with a variance growing as…
A column of grains in the jamming limit: glassy dynamics in the compaction process
J. M. Luck, Anita Mehta
We investigate a stochastic model describing a column of grains in the jamming limit, in the presence of a low vibrational intensity. The key control parameter of the model, , i…
On random symmetric matrices with a constraint: the spectral density of random impedance networks
J. Staering, B. Mehlig, Yan V. Fyodorov +1
We derive the mean eigenvalue density for symmetric Gaussian random N x N matrices in the limit of large N, with a constraint implying that the row sum of matrix elements should va…
