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-Markovianity in a dressed qubit with local dephasing
Saima Bashir, Muzaffar Qadir Lone, Prince A Ganai
We study the dynamics of a dressed qubit implemented by a spinless fermion hopping between two lattice sites with each site strongly coupled to a bath of phonons. We employ Lang-Fi…
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…
Decoherence dynamics in a polaron system with collective dephasing
Saima Bashir, Muzaffar Qadir Lone, Prince A Ganai
Within quantum information frameworks, managing decoherence stands as a pivotal task. The present work delves into decoherence dynamics of a dressed qubit, represented by a spinles…
