Full-wave nonlinear microscopy reveals guided channel for ultrafast polariton transport
Qingyi Zhou, Piper Fowler-Wright, Zongfu Yu +2
We show how finite-difference time-domain (FDTD) simulations can be extended to model ultrafast nonlinear microscopy, enabling the prediction of spatially-resolved pump--probe sign…
Coherent room-temperature dipole synchronization in nanocavity sheets
Rakesh Arul, Piper Fowler-Wright, Lille Borresen +3
Plasmonic nanocavities enable the synchronization of spatially distant emissive dipoles through strong near-field coupling in sub-nm gaps. We report formation of a room-temperature…
Dynamical Drexhage Effect: Amplified Emission in Time-Modulated Electromagnetic Environments
Juan Carlos Obeso Jureidini, Michael Reitz, Piper Fowler-Wright +4
We investigate the effect of nonrelativistic motion on the emission dynamics of a dipole emitter moving next to a reflecting interface. Within the formalism of macroscopic QED, we…
Theory of dynamical superradiance in organic materials
Lukas Freter, Piper Fowler-Wright, Javier Cuerda +3
We develop the theory of dynamical superradiance -- the collective exchange of energy between an ensemble of initially excited emitters and a single-mode cavity -- for organic mate…
Mapping molecular polariton transport via pump-probe microscopy
Piper Fowler-Wright, Michael Reitz, Joel Yuen-Zhou
We demonstrate how the transport properties of molecular polaritons in optical cavities can be extracted from a microscopic modeling of pump-probe spectroscopy. Our approach combin…
Non-Markovian effects in long-range polariton-mediated energy transfer
Kristin B. Arnardottir, Piper Fowler-Wright, Christos Tserkezis +2
Intramolecular energy transfer driven by near-field effects plays an important role in applications ranging from biophysics and chemistry to nano-optics and quantum communications.…
OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors
Gerald E. Fux, Piper Fowler-Wright, Joel Beckles +11
Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. De…
Mean-field and cumulant approaches to modelling organic polariton physics
Piper Fowler-Wright
In this thesis we develop methods for many-body open quantum systems and apply them to systems of organic polaritons. The methods employ a mean-field approach to reduce the dimensi…
Determining the validity of cumulant expansions for central spin models
Piper Fowler-Wright, Kristín B. Arnardóttir, Peter Kirton +2
For a model with many-to-one connectivity it is widely expected that mean-field theory captures the exact many-particle limit, and that higher-order cumulant expansion…
Efficient many-body non-Markovian dynamics of organic polaritons
Piper Fowler-Wright, Brendon W. Lovett, Jonathan Keeling
We show how to simulate a model of many molecules with both strong coupling to many vibrational modes and collective coupling to a single photon mode. We do this by combining proce…
