We study the magnetisation process of the one dimensional spin-1/2 antiferromagnetic Heisenberg model with modulated couplings over j=1,2,3 sites. It turns out that the evolution of magnetisation plateaus depends on j and on the wave number q of the ...

Quasi-periodic spin chains in a magnetic field
We study the interplay between a (quasi) periodic coupling array and an external magnetic field in a spin-1/2 XXZ chain. A new class of magnetization plateaux are obtained by means of Abelian bosonization methods which give rise to a sufficient ...

Site-centered impurities in quantum spin chains
The magnetic behavior of antiferromagnetic spin 1/2 chains with site-centered impurities in a magnetic field is investigated. The effect of impurities is implemented by considering different situations of both diagonal and off-diagonal disorder.

La cabra criolla santandereana
The Santanderean Creole Goat represents a valuable zoogenetic resource adapted to the semi-arid conditions of the Chicamocha Canyon in Colombia. This outreach article examines its productive traits, health challenges---particularly gastrointestinal parasitism caused by nematodes---and sustainable management strategies.
