Dynamical transitions in incommensurate systems
L. Consoli, H. Knops, A. Fasolino
In the dynamics of the undamped Frenkel-Kontorova model with kinetic terms, we find a transition between two regimes, a floating incommensurate and a pinned incommensurate phase. T…
Percolation mechanism for Colossal Magnetoresistance
Paul J. M. Bastiaansen, Hubert J. F. Knops
We argue that colossal magnetoresistance is a critical phenomenon and propose a mechanism to describe it. The mechanism relies on the halfmetallic behavior of the materials showing…
Is surface melting a surface phase transition?
Paul J. M. Bastiaansen, Hubert J. F. Knops
Monte Carlo or Molecular Dynamics calculations of surfaces of Lennard-Jones systems often indicate, apart from a gradual disordering of the surface called surface melting, the pres…
Roughening and preroughening in the six vertex model with an extended range of interaction
Paul J. M. Bastiaansen, Hubert J. F. Knops
We study the phase diagram of the BCSOS model with an extended interaction range using transfer matrix techniques, pertaining to the (100) surface of single component fcc and bcc c…
