Decorated Clusters and Geometrical Frustration in Cluster Spin Glass: A Random Graph Approach
S. G. Magalhaes, F. M. Zimmer, R. Erichsen
We develop a theory to investigate how geometrically frustrated clusters that become decorated affect the Cluster Spin Glass phase. The cluster structure is assumed to be a tetrahe…
Blume-Emery-Griffiths model on Random Graphs
R. Erichsen, Alexandre Silveira, S. G. Magalhaes
The Blume-Emery-Griffiths model with a random crystal field is studied in a random graph architecture, in which the average connectivity is a controllable parameter. The disordered…
Magnetic transitions induced by pressure and magnetic field in a two-orbital -electron model in cubic and tetragonal lattices
A. C. Lausmann, E. J. Calegari, Julián Faúndez +2
We investigate the onset and evolution of under the simultaneous application of pressure and magnetic field of distinct itinerant Néel states using the underscreened Anderson Latti…
Chiriality in a three-band superconducting prism in ZFC and FC processes
C. A. Aguirre, Julian Faundez, S. G. Magalhães +1
In the present work, we will study the superconducting properties of a mesoscopic three-dimensional prism with square transversal section under an external magnetic field in both Z…
Vortex matter in a two-band SQUID-shaped superconducting film
C. A. Aguirre, Julian Faundez, S. G. Magalhaes +1
In the present work we studied the magnetization, vorticity, Cooper pairs density and the space distribution of the local magnetic field in a three-dimensional superconductor with…
Role of Frustration in a Weakly Disordered Checkerboard Lattice
F. M. Zimmer, W. C. Silva, M. Schmidt +1
Quenched disorder effects on frustrated systems are explored by considering random fluctuations on the antiferromagnetic (AF) interactions between spins on the checkerboard lattice…
