Spin-1/2 string correlations and singlet-triplet gaps of frustrated ladders with ferromagnetic (F) legs and alternate F and AF rungs
Monalisa Chatterjee, Manoranjan Kumar, Zoltán G. Soos
The frustrated ladder with alternate ferromagnetic(F) exchange and AF exchange to first neighbors and F exchange to second neighbors is studied by exact diagona…
Quantum Phase Transitions in Skewed Ladder Systems
Sambunath Das, Dayasindhu Dey, Rajamani Raghunathan +3
In this brief review, we introduce a new spin ladder system called skewed spin ladders and discuss the exotic quantum phases of this system. The spin ladders studied are the 5/7, 3…
Singlet quantum phases and magnetization of the frustrated spin-1/2 ladder with ferromagnetic (F) exchange in legs and alternating F-AF exchange in rungs
Monalisa Chatterjee, Manoranjan Kumar, Zoltán G. Soos
The magnetization is used to identify three singlet quantum phases of the ladder with isotropic exchange interactions. The Dimer phase with frustrated F exchanges in rungs a…
Spin Peierls transition of and extended models with ferromagnetic .Sublattice dimerization and thermodynamics of zigzag chains in -TeVO
Manodip Routh, Sudip Kumar Saha, Manoranjan Kumar +1
The spin chain with ferromagnetic exchange between first neighbors and antiferromagnetic between second neighbors supports two spin-Peierls (SP) instabili…
Low temperature thermodynamics of the antiferromagnetic model: Entropy, critical points and spin gap
Sudip Kumar Saha, Manodip Routh, Manoranjan Kumar +1
The antiferromagnetic model is a spin-1/2 chain with isotropic exchange between first neighbors and between second neighbors. The model supports bo…
Density matrix renormalization group approach to the low temperature thermodynamics of correlated 1D fermionic models
Sudip Kumar Saha, Debasmita Maiti, Manoranjan Kumar +1
The low temperature thermodynamics of correlated 1D fermionic models with spin and charge degrees of freedom is obtained by exact diagonalization (ED) of small systems and followed…
