Polaron effects on the information backflow in Jaynes-Cummings model
Saima Bashir, Mehboob Rashid, Rayees A Malla +1
We investigate the influence of phonon degrees of freedom on the qubit dynamics in Jaynes-Cummings (JC) model. A strong qubit-phonon coupling is considered giving rise to Jaynes-Cu…
Non-Markovian amplitude damping in a central spin model with random couplings
Mehboob Rashid, Rayees A Mala, Saima Bashir +1
Non-Markovian dynamics is central to quantum information processing, as memory effects strongly influence coherence preservation, metrology, and communication. In this work, we inv…
Analysis of memory effects in the dynamic evolution of the spin-boson model
Rayees A Mala, Mehboob Rashid, Muzaffar Qadir Lone
Quantum information processing relies on how dynamics unfold in open quantum systems. In this work, we study the non-Markovian dynamics in the single mode spin-boson model at stron…
Dissipative dynamics of an interacting spin system with collective damping
Irfan A Dar, Faisal Farooq, Junaid Majeed +3
The competition between Hamiltonian and Lindblad dynamics in quantum systems give rise to non-equillibrium phenomena with no counter part in conventional condensed matter physics.…
