Light-Induced Quantum Self-Trapping of Vibrational Excitons in an Optical Cavity

Vincent Pouthier, Saad Yalouz

In an optical cavity, strong light--matter coupling between excitons and photons has been widely reported as a way to enhance energy delocalization through spatially extended polar…

Defect-Mediated Pairing and Dissociation of Strongly Correlated Electrons in Low Dimensional Lattices: The Quantum Taxi Effect

Vincent Pouthier, Saad Yalouz

We study the quantum dynamics of a strongly correlated electron pair in a one-dimensional lattice, focusing on the occurrence of local dissociation/pairing mechanisms induced by a…

Optimized excitonic transport mediated by local energy defects: survival of optimization laws in the presence of dephasing

Lucie Pepe, Vincent Pouthier, Saad Yalouz

In an extended star with peripheral defects and a core occupied by a trap, it has been shown that exciton-mediated energy transport from the periphery to the core can be optimized…

The extended star graph as a light-harvesting-complex prototype: excitonic absorption speedup by peripheral energy defect tuning

Saad Yalouz, Vincent Pouthier

We study the quantum dynamics of a photo-excitation uniformly distributed at the periphery of an extended star network (with branches of length ). More specifically, we…

Energy transfer in finite-size exciton-phonon systems : confinement-enhanced quantum decoherence

Vincent J. C. Pouthier

Based on the operatorial formulation of the perturbation theory, the exciton-phonon problem is revisited for investigating exciton-mediated energy flow in a finite-size lattice. Wi…

Vibrational exciton-mediated quantum state transfert: a simple model

Vincent J. C. Pouthier

A communication protocol is proposed in which quantum state transfer is mediated by a vibrational exciton. We consider two distant molecular groups grafted on the sides of a lattic…
