Magnetic plateaus and jumps in a spin-1/2 ladder with alternate Ising-Heisenberg rungs: a field dependent study
Sk Saniur Rahaman, Manoranjan Kumar, Shaon Sahoo
We study a frustrated two-leg spin-1/2 ladder with alternate Ising and isotropic Heisenberg rung exchange interactions, whereas, interactions along legs and diagonals are Ising typ…
Ground state properties and exact thermodynamics of a 2-leg anisotropic spin ladder system
Sk Saniur Rahaman, Shaon Sahoo, Manoranjan Kumar
We study a frustrated two-leg spin ladder with alternate isotropic Heisenberg and Ising rung exchange interactions, whereas, interactions along legs and diagonals are Ising-type. A…
Periodically Driven Many-Body Systems: A Floquet Density Matrix Renormalization Group Study
Shaon Sahoo, Imke Schneider, Sebastian Eggert
Driving a quantum system periodically in time can profoundly alter its long-time correlations and give rise to exotic quantum states of matter. The complexity of the combination of…
Haldane and Dimer phases in a frustrated spin chain: an exact groundstate and associated topological phase transition
Shaon Sahoo, Dayasindhu Dey, Sudip Kumar Saha +1
A Heisenberg spin- chain with alternating ferromagnetic () and antiferromagnetic () nearest-neighbor (NN) interactions, exhibits the Dimer and spin- Halda…
Studies on a frustrated Heisenberg spin chain with alternating ferromagnetic and antiferromagnetic exchanges
Shaon Sahoo, V. M. L. Durga Prasad Goli, Diptiman Sen +1
We study Heisenberg spin-1/2 and spin-1 chains with alternating ferromagnetic () and antiferromagnetic () nearest-neighbor interactions and a ferromagnetic next-neare…
Quantum phases of dimerized and frustrated Heisenberg spin chains with s = 1/2, 1 and 3/2: an entanglement entropy and fidelity study
V. M. L. Durga Prasad Goli, Shaon Sahoo, S. Ramasesha +1
We study here different regions in phase diagrams of the spin-1/2, spin-1 and spin-3/2 one dimensional antiferromagnetic Heisenberg systems with frustration (next-nearest-neighbor…
