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…
On the existence of twin prime in an interval
Shaon Sahoo
Let , where , is the -th prime and . If $M_α(x…
On twin prime distribution and associated biases
Shaon Sahoo
A modified totient function () is seen to play a significant role in the study of the twin prime distribution. The function is defined as $ϕ_2(n):=\#\{a\le n ~\vert ~\textrm{$…
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…
