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…
Taming the 3D Wilson-Fisher Fixed Point via Nonlocal Effective Action
Hyeon Jung Kim, Seung-Jong Yoo, Jinmo Bok +3
We present a Renormalization Group (RG) framework based on a nonlocal effective action ansatz to analyze the strong coupling dynamics of the three-dimensional relativistic …
Unique entanglement time evolution of two-qubit product separable and extended Werner-like states in a discrete qubit environment
Renzo P. Alporha, Lemuel John F. Sese, Rayda P. Gammag
This study investigates the parameters affecting the entanglement time evolution of product separable (PS) and extended Werner-like (EWL) states in homogeneous, white noise, and mi…
