Revealing effects of local dimension on variable-range interacting model by connecting Lieb-Robinson bounds and multipartite entanglement
Keshav Das Agarwal, Debkanta Ghosh, Pritam Halder +1
A spin- variable-range interacting Ising model may display qualitatively different behaviors depending on the fall-off rate of the interactions, as already seen in equilibrium s…
Entanglement of weighted graphs uncovers transitions in variable-range interacting models
Debkanta Ghosh, Keshav Das Agarwal, Pritam Halder +1
The cluster state acquired by evolving the nearest-neighbor (NN) Ising model from a completely separable state is the resource for measurement-based quantum computation. Instead of…
Recognizing critical lines via entanglement in non-Hermitian systems
Keshav Das Agarwal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
The non-Hermitian model exhibits counterintuitive phenomena that are not observed in the Hermitian counterparts. To probe the competition between non-Hermitian and Hermitian intera…
