Specific heat of MgB in a one- and a two-band model from first-principles calculations
A. A. Golubov, J. Kortus, O. V. Dolgov +6
The heat capacity anomaly at the transition to superconductivity of the layered superconductor MgB is compared to first-principles calculations with the Coulomb repulsion, $μ^\…
Multiband model for tunneling in MgB2 junctions
A. Brinkman, A. A. Golubov, H. Rogalla +5
A theoretical model for quasiparticle and Josephson tunneling in multiband superconductors is developed and applied to MgB2-based junctions. The gap functions in different bands in…
Symmetries in jump-diffusion models with applications in option pricing and credit risk
Jiri Hoogland, Dimitri Neumann, Michel Vellekoop
It is a well known fact that local scale invariance plays a fundamental role in the theory of derivative pricing. Specific applications of this principle have been used quite often…
Spin Torques in Ferromagnetic/Normal Metal Structures
K. Xia, P. J. Kelly, G. E. W. Bauer +2
Recent theories of spin-current-induced magnetization reversal are formulated in terms of a spin-mixing conductance . We evaluate from first-principles for a num…
Orbital excitations in LaMnO
Jeroen van den Brink
We study the recently observed orbital excitations, orbitons, and treat electron-electron correlations and lattice dynamics on equal footing. It is shown that the orbiton energy an…
Observation of band structure and density of states effects in Co-based magnetic tunnel junctions
P. LeClair, J. T. Kohlhepp, C. H. van de Vin +7
Utilizing Co/AlO/Co magnetic tunnel junctions (MTJs) with Co electrodes of different crystalline phases, a clear relationship between electrode structure and junction trans…
Transformations of CCP programs
Sandro Etalle, Maurizio Gabbrielli, Maria Chiara Meo
We introduce a transformation system for concurrent constraint programming (CCP). We define suitable applicability conditions for the transformations which guarantee that the input…
Critical temperature of superconductor/ferromagnet bilayers
Ya. V. Fominov, N. M. Chtchelkatchev, A. A. Golubov
Superconductor/ferromagnet bilayers are known to exhibit nontrivial dependence of the critical temperature T_c on the thickness d_f of the ferromagnetic layer. We develop a general…
Superconducting Quantum Interference Device based on MgB2 nanobridges
A. Brinkman, D. Veldhuis, D. Mijatovic +4
The recently discovered superconductor MgB2, with a transition temperature of 39K, has significant potential for future electronics. An essential step is the achievement of Josephs…
Photoemission spectra of LaMnO3 controlled by orbital excitations
Jeroen van den Brink, Peter Horsch, Andrzej M. Oles
We investigate the spectral function of a hole moving in the orbital-ordered ferromagnetic planes of LaMnO, and show that it depends critically on the type of orbital ordering.…
Superconducting Mg-B films by pulsed laser deposition in an in-situ two-step process using multi-component targets
D. H. A. Blank, H. Hilgenkamp, A. Brinkman +3
Superconducting thin films have been prepared in a two-step in-situ process, using the Mg-B plasma generated by pulsed laser ablation. The target was composed of a mixture of Mg an…
Hysteretic clustering in granular gas
Ko van der Weele, Devaraj van der Meer, Michel Versluis +1
Granular material is vibro-fluidized in N=2 and N=3 connected compartments, respectively. For sufficiently strong shaking the granular gas is equi-partitioned, but if the shaking i…
Bifurcation Diagram for Compartmentalized Granular Gases
Devaraj van der Meer, Ko van der Weele, Detlef Lohse
The bifurcation diagram for a vibro-fluidized granular gas in N connected compartments is constructed and discussed. At vigorous driving, the uniform distribution (in which the gas…
Superconducting thin films of MgB2 on (001)-Si by pulsed laser deposition
A. Brinkman, D. Mijatovic, G. Rijnders +9
Superconducting thin films have been prepared on Si-substrates, using pulsed laser deposition from a target composed of a mixture of Mg and MgB2 powders. The films were deposited a…
Discrete Breathers in Josephson Ladders
E. Trias, J. J. Mazo, A. Brinkman +1
We present a study of nonlinear localized excitations called discrete breathers in a superconducting array. These localized solutions were recently observed in Josephson-junction l…
Degenerate ground state in a mesoscopic YBaCuO grain boundary Josephson junction
E. Il'ichev, M. Grajcar, R. Hlubina +8
We have measured the current-phase relationship (CPR) of symmetric 45 degree YBaCuO grain boundary Josephson junctions. Substantial deviations of the CPR from conventional tunnel-j…
Depairing currents in the superconductor/ferromagnet proximity system Nb/Fe
J. M. E. Geers, M. B. S. Hesselberth, J. Aarts +1
We have investigated the behaviour of the depairing current J_{dp} in ferromagnet/superconductor/ferromagnet (F/S/F) trilayers as function of the thickness d_s of the superconducti…
