Landau Levels in the Presence of Topological Defects

G. de A. Marques, Claudio Furtado, V. B. Bezerra +1

We study the Landau levels associated with electrons moving in a magnetic field in the presence of a continuous distribution of disclinations, a magnetic screw dislocation and a di…

Average Time Spent by Levy Flights and Walks on an Interval with Absorbing Boundaries

S. V. Buldyrev, S. Havlin, A. Ya. Kazakov +4

We consider a Levy flyer of order alpha that starts from a point x0 on an interval [O,L] with absorbing boundaries. We find a closed-form expression for the average number of fligh…

The Saffman-Taylor problem on a sphere

F. Parisio, F. Moraes, Jose A. Miranda +1

The Saffman-Taylor problem addresses the morphological instability of an interface separating two immiscible, viscous fluids when they move in a narrow gap between two flat paralle…

Biot-Savart-like law in electrostatics

Mario H. Oliveira, Jose A. Miranda

The Biot-Savart law is a well-known and powerful theoretical tool used to calculate magnetic fields due to currents in magnetostatics. We extend the range of applicability and the…

Rotating Hele-Shaw cells with ferrofluids

Jose A. Miranda

We investigate the flow of two immiscible, viscous fluids in a rotating Hele-Shaw cell, when one of the fluids is a ferrofluid and an external magnetic field is applied. The interp…

Gravity-driven instability in a spherical Hele-Shaw cell

Jose A. Miranda, Fernando Parisio, Fernando Moraes +1

A pair of concentric spheres separated by a small gap form a spherical Hele-Shaw cell. In this cell an interfacial instability arises when two immiscible fluids flow. We derive the…
