Quantum phases of spin-1 system on 3/4 and 3/5 skewed ladders
Sambunath Das, Dayasindhu Dey, S. Ramasesha +1
We study the quantum phase transitions of frustrated antiferromagnetic Heisenberg spin-1 systems on the 3/4 and 3/5 skewed two leg ladder geometries. These systems can be viewed as…

Quantum phases of a frustrated spin-1 system: The 5/7 skewed ladder
Sambunath Das, Dayasindhu Dey, Manoranjan Kumar +1
The quantum phases in a spin-1 skewed ladder system formed by alternately fusing five- and seven-membered rings are studied numerically using the exact diagonalization technique up…

Magnetization plateaus of spin- system on a 5/7 skewed ladder
Dayasindhu Dey, Sambunath Das, Manoranjan Kumar +1
Magnetization plateaus are some of the most striking manifestations of frustration in low-dimensional spin systems. We present numerical studies of magnetization plateaus in the fa…
