Predicting Critical Phases from Entanglement Dynamics in XXZ Alternating Chain
Keshav Das Agarwal, Leela Ganesh Chandra Lakkaraju, Aditi Sen De
The quantum XXZ spin model with alternating bond strengths under magnetic field has a rich equilibrium phase diagram which includes Haldane, Luttinger liquid, singlet, and paramagn…
Detection of unbroken phase of non-Hermitian system via Hermitian factorization surface
Leela Ganesh Chandra Lakkaraju, Aditi Sen De
In the traditional quantum theory, one-dimensional quantum spin models possess a factorization surface where the ground states are fully separable having vanishing bipartite as wel…
Necessary condition for information transfer under simulated parity-time-symmetric evolution
Leela Ganesh Chandra Lakkaraju, Shiladitya Mal, Aditi Sen De
Parity-time (PT) symmetric quantum theory can broaden the scope of quantum dynamics beyond unitary evolution which may lead to numerous counter-intuitive phenomena, including singl…
