Continuum model of actin-mediated bacterial propulsion
- V.G.Benza
- Engineering
- 28 February 2007
The mechanism of propulsion of host bacteria under the action of actin gel networks is examined by means of a continuum model of the dynamics of the F-actin concentration. The model includes the…
Non-hermitean delocalization in an array of wells with variable-range widths
- V.G.Benza
- Physics
- 2 June 2000
Nonhermitean hamiltonians of convection-diffusion type occur in the description of vortex motion in the presence of a tilted magnetic field as well as in models of driven population dynamics. We…
Hopping with time-dependent disorder
- G.C.Ferrario, V.G.Benza
- Physics
- 1 July 1999
We determine the propagation properties of a quantum particle in a d-dimensional lattice with hopping disorder, delta-correlated in time. The system is delocalized: the averaged transition…
Spinless particle in rapidly fluctuating random magnetic field
- V.G.Benza, B.Cardinetti
- Physics
- 26 March 1998
We study a two-dimensional spinless particle in a disordered gaussian magnetic field with short time fluctuations, by means of the evolution equation for the density matrix $$; in this description…
