Exact Fractionalized Ground States in an Extended Spin-1 Kitaev Chain
Alwyn Jose Raja, R. Ganesh
Inspired by the Affleck-Kennedy-Lieb-Tasaki (AKLT) model, we present exact solutions for a spin-1 chain with Kitaev-like couplings. We consider an expanded Kitaev model with biline…

Spin-basis wavefunctions for the one-dimensional Kitaev model
Alwyn Jose Raja, Rajesh Narayanan, R. Ganesh
Magnetic phases with quantum entanglement are often expressed in terms of parton wavefunctions. Relatively few examples are known where wavefunctions can be directly written down i…

Measuring dark state number in the Tavis-Cummings model
L. Theerthagiri, Rajesh Narayanan, R. Ganesh
Quantum mechanics allows for light-matter setups that hold excitations without releasing them as light. Arising from destructive interference processes, they are best seen in a Tav…
