More sublattices of the lattice of local clones
Michael Pinsker
We investigate the complexity of the lattice of local clones over a countably infinite base set. In particular, we prove that this lattice contains all algebraic lattices with at m…
Infinite combinatorial issues raised by lifting problems in universal algebra
Friedrich Wehrung
The critical point between varieties A and B of algebras is defined as the least cardinality of the semilattice of compact congruences of a member of A but of no member of B, if it…
Magnetic field dependent specific heat and enhanced Wilson ratio in strongly correlated layered cobalt oxide
P. Limelette, H. Muguerra, S. Hebert
We have investigated the low temperature specific heat properties as a function of magnetic field in the strongly correlated layered cobalt oxide [BiBaKO]CoO$…
The lower central and derived series of the braid groups of the projective plane
Daciberg Lima Gonçalves, John Guaschi
We determine the lower central and derived series of the n-string braid groups B_n(RP^2) of the real projective plane. We are motivated in part by the study of Fadell-Neuwirth shor…
Tailoring magnetic anisotropy in epitaxial half metallic La0.7Sr0.3MnO3 thin films
P. Perna, C. Rodrigo, E. Jiménez +5
We present a detailed study on the magnetic properties, including anisotropy, reversal fields, and magnetization reversal processes, of well characterized half-metallic epitaxial L…
Migration of nuclear shell gaps studied in the d(24Ne,p gamma)25Ne reaction
W. N. Catford, C. N. Timis, R. C. Lemmon +26
The transfer of neutrons onto 24Ne has been measured using a reaccelerated radioactive beam of 24Ne to study the (d,p) reaction in inverse kinematics. The unusual raising of the fi…
