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…
The Transfer Tensor Method: an Analytical Study Case
Marcel Morillas-Rozas, Alberto López-GarcÃa, Gonzalo Reina Rivero +2
The transfer tensor method is a versatile tool for analyzing and propagating general open quantum systems. It captures in a compact manner all memory effects in a non-Markovian sys…
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…
Quantum Beatings in Optical Cavities
Ishaan Ganti, Jianshu Cao
Cavity polaritons, quasiparticles formed by coherent light-matter coupling, are at the heart of fundamental concepts of quantum optics. The quintessential signature of this coheren…
Dynamical generation and transfer of nonclassical states in strongly interacting light-matter systems in cavities
Ilia Tutunnikov, Vasil Rokaj, Jianshu Cao +1
We propose leveraging strong and ultrastrong light-matter coupling to efficiently generate and exchange nonclassical light and quantum matter states. Two initial conditions are con…
Unusual Diffusivity in Strongly Disordered Quantum Lattices: Random Dimer Model
Ilia Tutunnikov, Jianshu Cao
Recent advances in transport properties measurements of disordered materials and lattice simulations, using superconducting qubits, have rekindled interest in Anderson localization…
