Neel order, ring exchange and charge fluctuations in the half-filled Hubbard model
J. -Y. P. Delannoy, M. J. P. Gingras, P. C. W. Holdsworth +1
We investigate the ground state properties of the two dimensional half-filled one band Hubbard model in the strong (large-U) to intermediate coupling limit ({\it i.e.} away from th…
The cohomology structure of string algebras
Juan Carlos Bustamante
We show that the graded commutative ring structure of the Hochschild cohomology HH*(A) is trivial in case A is a triangular quadratic string algebra. Moreover, in case A isgentle,…
Field-dependent diamagnetic transition in magnetic superconductor
R. Prozorov, D. D. Lawrie, I. Hetel +2
The magnetic penetration depth of single crystal was measured down to 0.4 K in dc fields up to 7 kOe. For insulating , Sm…
Abelian exact subcategories closed under predecessors
Ibrahim Assem, Manuel Saorin
In the category of finitely generated modules over an artinian ring, we classify all the abelian exact subcategories closed under predecessors or, equivalently, all the split torsi…
