Interaction-Endowed PT-Symmetry and its Effects on Decoherence, Einselection, and Non-Markovianity in a Central Spin Model
Leoj Phoebe M. Esquierdo, Lemuel John F. Sese, Rayda P. Gammag
We have introduced PT-symmetry to a central spin model by adding a PT-symmetric interaction with a tunable hermiticity parameter . Using the pseudo-Hermitian formalism, we appl…

Coupling effect of nearest-neighbor interacting qubit chains to a single qubit system
Manuel Allan L. Orongan, Lemuel John F. Sese, Rayda P. Gammag
This study establishes a theorem that provides sufficient criteria for identifying terms in any time-independent Hamiltonian that have no influence on local dynamics, local observa…
