Exotic magnetisation plateaus in a quasi-2D Shastry-Sutherland model
G. R. Foltin, S. R. Manmana, K. P. Schmidt
We find unconventional Mott insulators in a quasi-2D version of the Shastry-Sutherland model in a magnetic field. In our realization on a 4-leg tube geometry, these are stabilized…
Magnetization of SrCu2(BO3)2 in ultrahigh magnetic fields up to 118 T
Y. H. Matsuda, N. Abe, S. Takeyama +7
The magnetization process of the orthogonal-dimer antiferromagnet SrCu2(BO3)2 is investigated in high magnetic fields of up to 118 T. A 1/2 plateau is clearly observed in the field…
Microscopic mechanism for the 1/8 magnetization plateau in SrCu_2(BO_3)_2
M. Nemec, G. R. Foltin, K. P. Schmidt
The frustrated quantum magnet SrCu_2(BO_3)_2 shows a remarkably rich phase diagram in an external magnetic field including a sequence of magnetization plateaux. The by far experime…
The morphology of nodal lines-random waves versus percolation
Georg Foltin, Sven Gnutzmann, Uzy Smilansky
In this paper we investigate the properties of nodal structures in random wave fields, and in particular we scrutinize their recently proposed connection with short-range percolati…
Counting nodal domains
Georg Foltin
We consider the nodal domains of Gaussian random waves in two dimensions. We present a method to calculate the distribution of the number of nodal domains and the average connectiv…
The distribution of extremal points of Gaussian scalar fields
Georg Foltin
We consider the signed density of the extremal points of (two-dimensional) scalar fields with a Gaussian distribution. We assign a positive unit charge to the maxima and minima of…
