Periodically driven three-dimensional Kitaev model
Soumya Sasidharan, Naveen Surendran
We study the dynamics of a three-dimensional generalization of Kitaev's honeycomb lattice spin model (defined on the hyperhoneycomb lattice) subjected to a harmonic driving of $J_z…
Dynamical freezing and switching in periodically driven bilayer graphene
Soumya Sasidharan, Naveen Surendran
A class of integrable models, such as the one-dimensional transverse-field Ising model, respond nonmonotonically to a periodic drive with respect to the driving parameters and free…
Topological entanglement entropy of three-dimensional Kitaev model
N. C. Randeep, Naveen Surendran
We calculate the topological entanglement entropy (TEE) for a three-dimensional hyperhoneycomb lattice generalization of Kitaev's honeycomb lattice spin model. We find that for thi…
Topological excitations in three dimensional Kitaev model
Saptarshi Mandal, Naveen Surendran
We study the excitations in a three dimensional version of Kitaev's spin-1/2 model on the honeycomb lattice introduced by the present authors recently. The gapped phase of the syst…
Exact Haldane mapping for all and super universality in spin chains
A. M. M. Pruisken, R. Shankar, N. Surendran
The low energy dynamics of the anti-ferromagnetic Heisenberg spin chain in the semiclassical limit is known to map onto the O(3) nonlinear model with a ter…
Exactly solvable Kitaev model in three dimensions
Saptarshi Mandal, Naveen Surendran
We introduce a spin-1/2 model in three dimensions which is a generalization of the well-known Kitaev model on a honeycomb lattice. Following Kitaev, we solve the model exactly by m…
