Conical diffraction intensity profiles generated using a top-hat input beam
Donegan, John; Lunney, James; Eastham, Paul; Mc Closkey, David (2014) -
Localization and self-trapping in driven-dissipative polariton condensates
Eastham, Paul; Bello, Frank (2017) -
Near-field relaxation of a quantum emitter to 2D semiconductors: surface dissipation and exciton polaritons
Eastham, Paul; Bradley, Louise; Karanikolas, Vasilios D.; Marocico, Cristian A. (2016)The total spontaneous emission rate of a quantum emitter in the presence of an infinite MoS2 monolayer is enhanced by several orders of magnitude, compared to its free-space value, due to the excitation of surface exciton ... -
Optimizing performance of quantum operations with non-Markovian decoherence: the tortoise or the hare?
Eastham, Paul (2024)The interaction between a quantum system and its environment limits our ability to control it and perform quantum operations on it. We present an efficient method to find optimal controls for quantum systems coupled to ... -
Quantum control of excitons for reversible heat transfer
Eastham, Paul (2019)Lasers, photovoltaics, and thermoelectrically-pumped light emitting diodes are thermodynamic machines which use excitons (electron-hole pairs) as the working medium. The heat transfers in such devices are highly irreversible, ... -
Quantum heat statistics with time-evolving matrix product operators
Eastham, Paul; Mitchison, Mark T.; Popovic, Maria; Goold, John (2021)We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix product operator algorithm. This approach is ... -
Synchronization crossover of polariton condensates in weakly disordered lattices
Eastham, Paul (2018) -
Synchronization in disordered oscillator lattices: Nonequilibrium phase transition for driven-dissipative bosons
Eastham, Paul (2021)We show that lattices of phase oscillators with random natural frequencies undergo a transition from a desynchronized to a synchronized state for dimensions d<4. The oscillators are described by a generalization of the ... -
Weyl points and exceptional rings with polaritons in bulk semiconductors
Eastham, Paul (2020)Weyl points are the simplest topologically protected degeneracy in a three-dimensional dispersion relation. The realization of Weyl semimetals in photonic crystals has allowed these singularities and their consequences to ...
