Noise-enhanced Ballistic Expansion of Polariton Wave-packets in a Multimode Cavity
Ilia Tutunnikov, Md Qutubuddin, H. R. Sadeghpour +1
Advances in optical measurements enable precise tracking of cavity polariton wave-packets across broad spatial and temporal ranges, but how dephasing reshapes their real-space dyna…

Complementarity Beyond Definite Causal Order
Mohd Asad Siddiqui, Md Qutubuddin, Tabish Qureshi
Wave--particle duality is a cornerstone of quantum mechanics, traditionally formulated under definite causal order. We investigate how complementarity is modified when the temporal…

Characterization of Polariton Dynamics in a Multimode Cavity (II): Coherent-Incoherent Transition Driven by Photon Loss
Md Qutubuddin, Ilia Tutunnikov, Jianshu Cao
Motivated by the recent advances in optical imaging and tracking of wave-packet propagation in optical cavities, we systematically explore the non-Hermitian polariton dynamics with…
