Electron Transport through the Two-dimensional Atomic Lattice

The electrical conductivity changes of the Si(111)-(6x6)Au surface at early stage of Pb deposition was studied experimentally and theoretically as a function of coverage. Pb deposition onto a Si(111)-(6x6)Au surface induce strong change of the conductance even at a low coverage (< 1 monolayer). The experimental results are analyzed using the theoretical model of two dimensional (2D) square atom...

FUZZY HV -SUBSTRUCTURES IN A TWO DIMENSIONAL EUCLIDEAN VECTOR SPACE

In this paper, we study fuzzy substructures in connection withHv-structures. The original idea comes from geometry, especially from thetwo dimensional Euclidean vector space. Using parameters, we obtain a largenumber of hyperstructures of the group-like or ring-like types. We connect,also, the mentioned hyperstructures with the theta-operations to obtain morestrict hyperstructures, as Hv-groups...

Mott-insulator phase of coupled one-dimensional atomic gases in a two-dimensional optical lattice.

We consider the 2D Mott-insulator state of a 2D array of coupled finite size 1D Bose gases. It is shown that the momentum distribution in the lattice plane is very sensitive to the interaction regime in the 1D tubes. In particular, we find that the disappearance of the interference pattern in time-of-flight experiments is a clear consequence of the strongly interacting Tonks-Girardeau regime al...

Two-dimensional atomic crystals.

We report free-standing atomic crystals that are strictly 2D and can be viewed as individual atomic planes pulled out of bulk crystals or as unrolled single-wall nanotubes. By using micromechanical cleavage, we have prepared and studied a variety of 2D crystals including single layers of boron nitride, graphite, several dichalcogenides, and complex oxides. These atomically thin sheets (essentia...

Lattice study of the gluon propagator in momentum space.

We consider pure glue QCD at β = 5.7, β = 6.0 and β = 6.3. We evaluate the gluon propagator both in time at zero 3-momentum and in momentum space. From the former quantity we obtain evidence for a dynamically generated effective mass, which at β = 6.0 and β = 6.3 increases with the time separation of the sources, in agreement with earlier results. The momentum space propagator G(k) provides fur...
