Detecting exceptional points through dynamics in non-Hermitian systems
Keshav Das Agarwal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Non-Hermitian rotation-time reversal (RT)-symmetric spin models possess two distinct phases, the unbroken phase in which the entire spectrum is real and the broken phase which cont…

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…
