A universal approach for drainage basins
Erneson A. Oliveira, Rilder S. Pires, Rubens S. Oliveira +3
Drainage basins are essential to Geohydrology and Biodiversity. Defining those regions in a simple, robust and efficient way is a constant challenge in Earth Science. Here, we intr…
Landau levels in wrinkled and rippled graphene sheets
Kyriakos Flouris, Miller Mendoza, Hans J. Herrmann
We study the discrete energy spectrum of curved graphene sheets in the presence of a magnetic field. The shifting of the Landau levels is determined for complex and realistic geome…
Avalanche Dynamics and Correlations in Neural Systems
Fabrizio Lombardi, Hans J. Herrmann, L. de Arcangelis
The existence of power-law distributions is only a first requirement in the validation of the critical behavior of a system. Long-range spatio-temporal correlations are fundamental…
Confining massless Dirac particles in two-dimensional curved space
Kyriakos Flouris, Miller Mendoza Jimenez, Jens-Daniel Debus +1
Dirac particles have been notoriously difficult to confine. Implementing a curved space Dirac equation solver based on the quantum Lattice Boltzmann method, we show that curvature…
Perturbing the Shortest Path on a Critical Directed Square Lattice
Fabian Hillebrand, Mirko Luković, Hans J. Herrmann
We investigate the behaviour of the shortest path on a directed two-dimensional square lattice for bond percolation at the critical probability . We observe that flipping an…
Percolation on Isotropically Directed Lattice
Aurelio W. T. de Noronha, André A. Moreira, André P. Vieira +3
We investigate percolation on a randomly directed lattice, an intermediate between standard percolation and directed percolation, focusing on the isotropic case in which bonds on o…
