Density matrix renormalization group (DMRG) for cyclic and centrosymmetric linear chains
Manoranjan Kumar, Dayasindhu Dey, Aslam Parvej +2
The density matrix renormalization group (DMRG) method generates the low-energy states of linear systems of sites with a few degrees of freedom at each site by starting with a…

Magnetic Field Induced Exotic Phases in Isotropic Frustrated Spin-1/2 chain
Aslam Parvej, Manoranjan Kumar
The frustrated isotropic model with ferromagnetic and anti-ferromagnetic interactions in presence of an axial magnetic field shows many exotic phases, such as…
