Gapless points of dimerized quantum spin chains: analytical and numerical studies
V. Ravi Chandra, Diptiman Sen, Naveen Surendran
We study the locations of the gapless points which occur for quantum spin chains of finite length (with a twisted boundary condition) at particular values of the nearest neighbor d…

Exact magnetization plateaus and phase transitions in spin-S Heisenberg antiferromagnets in arbitrary dimensions
V. Ravi Chandra, Naveen Surendran
We generalize a class of Heisenberg antiferromagnets in one, two and three dimensions, which have been shown to exhibit magnetization plateaus for spin-1/2. In a certain parameter…
