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…

Quantum phases of ferromagnetically coupled dimers on Shastry-Sutherland lattice
Monalisa Chatterjee, Santanu Pal, Manoranjan Kumar
The ground state (gs) of antiferromagnetically coupled dimers on the Shastry-Sutherland lattice (SSL) stabilizes many exotic phases and has been extensively studied. The gs propert…
