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 appli…
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…
Distribution of critical temperature at Anderson localization
Rayda Gammag, Ki-Seok Kim
Based on a local mean-field theory approach at Anderson localization, we find a distribution function of critical temperature from that of disorder. An essential point of this loca…
Two-dimensional electron gas tilt-induced Landau level crossings
Rayda Gammag, Cristine Villagonzalo
This work elucidates the novel behavior found in a two-dimensional electron gas (2DEG) under a tilted magnetic field in which the field's angle becomes the dominant factor in tunin…
Enhancement of the superconducting transition temperature from the competition between electron-electron correlations and electron-phonon interactions
Rayda Gammag, Ki-Seok Kim
We uncover that the competition between electron-electron correlations and electron-phonon interactions gives rise to unexpectedly huge enhancement of the superconducting transitio…
Persistent spin splitting of a two-dimensional electron gas in tilted magnetic fields
Rayda Gammag, Cristine Villagonzalo
By varying the orientation of the applied magnetic field with respect to the normal of a two-dimensional electron gas, the chemical potential and the specific heat reveal persisten…
