Local Symmetries and Order-Disorder Transitions in Small Macroscopic Wigner Islands
Gwennou Coupier, Claudine Guthmann, Yves Noat +1
The influence of local order on the disordering scenario of small Wigner islands is discussed. A first disordering step is put in evidence by the time correlation functions and is…
Enhancement of mobilities in a pinned multidomain crystal
Gwennou Coupier, Michel Saint Jean, Claudine Guthmann
Mobility properties inside and around degenerate domains of an elastic lattice partially pinned on a square array of traps are explored by means of a fully controllable model syste…
Single File Diffusion enhancement in a fluctuating modulated 1D channel
Gwennou Coupier, Michel Saint Jean, Claudine Guthmann
We show that the diffusion of a single file of particles moving in a fluctuating modulated 1D channel is enhanced with respect to the one in a bald pipe. This effect, induced by th…
Single file diffusion in macroscopic Wigner rings
Gwennou Coupier, Michel Saint Jean, Claudine Guthmann
The single file diffusion in a circular channel of millimetric charged balls is studied. The evolution in time of the mean square displacement is shown to be subdiffusive, but slow…
Determination of the interactions in confined macroscopic Wigner islands: theory and experiments
P. Galatola, G. Coupier, M. Saint Jean +2
Macroscopic Wigner islands present an interesting complementary approach to explore the properties of two-dimensional confined particles systems. In this work, we characterize theo…
Dispersive charge transport along the surface of an insulating layer observed by Electrostatic Force Microscopy
J. S. Lambert, G. De Loubens, C. Guthmann +2
We report the observation in the direct space of the transport of a few thousand charges submitted to a tunable electric field along the surface of a silicon oxide layer. Charges a…
