Peano modes at the D=2 delocalization transition
Vincenzo G. Benza
We study the relaxation of the Peano chain's deformations in the presence of gaussian noise. The D=2 spring network which models the chain's elasticity has no bulk, but only bounda…
Physical descriptions of the bacterial nucleoid at large scales, and their biological implications
Vincenzo G. Benza, Bruno Bassetti, Kevin D. Dorfman +4
Recent experimental and theoretical approaches have attempted to quantify the physical organization (compaction and geometry) of the bacterial chromosome with its complement of pro…
Theory of Tunneling Spectroscopy in a Mn Single-Electron Transistor by Density-Functional Theory Methods
L. Michalak, C. M. Canali, M. R. Pederson +2
We consider tunneling transport through a Mn molecular magnet using spin density functional theory. A tractable methodology for constructing many-body wavefunctions from Koh…
Electron-magnon coupling and nonlinear tunneling transport in magnetic nanoparticles
L. Michalak, C. M. Canali, V. G. Benza
We present a theory of single-electron tunneling transport through a ferromagnetic nanoparticle in which particle-hole excitations are coupled to spin collective modes. The model e…
Landau-Zener quantum tunneling in disordered nanomagnets
V. G. Benza, C. M. Canali, G. Strini
We study Landau-Zener macroscopic quantum transitions in ferromagnetic metal nanoparticles containing on the order of 100 atoms. The model that we consider is described by an effec…
The Landau-Zener Model with Decoherence: The case S=1/2
V. G. Benza, G. Strini
We study the dynamics of a spin coupled to an oscillating magnetic field, in the presence of decoherence and dissipation. In this context we solve the master equation for the Landa…
