Predicting topological quantum phase transition from dynamics via multisite entanglement
Leela Ganesh Chandra Lakkaraju, Sudip Kumar Haldar, Aditi Sen De
An exactly solvable Kitaev model in a two-dimensional square lattice exhibits a topological quantum phase transition which is different from the symmetry-breaking transition at zer…
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…
Mimicking quantum correlation of a long-range Hamiltonian by finite-range interactions
Leela Ganesh Chandra Lakkaraju, Srijon Ghosh, Debasis Sadhukan +1
The quantum long-range extended Ising model possesses several striking features that cannot be observed in the corresponding short-range model. We report that the pattern obtained…
Quantum battery with non-Hermitian charging
Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju, Aditi Sen De
We propose a design of a quantum battery exploiting the non-Hermitian Hamiltonian as a charger. In particular, starting with the ground or the thermal state of the interacting (non…
