Research Interests: I am interested in phase transitions and dynamics of non-equilibrium systems, renormalization group theory, gauge theories, ultra-cold quantum physics, strongly correlated many-body systems, and the simulation of synthetic gauge fields.

Research Interests: I am interested in the superfluid properties of microcavity-polaritons, which are quasi-particles that result from the strong-coupling of cavity photons and quantum well excitons. Experimental observations have shown polaritons to exhibit aspects of superfluid behaviour, like suppressed scattering and quantised vortices. However, superfluidity is more complicated in non-equilibrium systems like polaritons because the system must be driven by a laser, which affects the excitation spectrum and consequently the flow properties. I study superfluidity in polaritons by using Keldysh field theory, which allows the construction of path integrals in non-equilibrium systems, to calculate the response functions of the system.

Paul Brookes

Research Interests: My overall interest is how circuit-QED can be used in the construction of processors and memories for quantum computation. Within this field my research is focused on developing novel readout protocols based on non-linear effects in the Jaynes-Cummings model of a qubit coupled to a microwave resonator. In particular I study a phenomenon known as bistability in which a driven anharmonic oscillator has two different steady state modes of oscillation with different amplitudes and phases. In collaboration with experimental groups we hope to harness this effect to design new and more simple methods of high fidelity qubit readout which differ from previous applications of bistability such as the Josephson Bifurcation Amplifier.

Alex Ferrier

Research Interests: My research interests include order and phase transitions in non-equilibrium many-body quantum systems, and phase space methods for simulating driven-dissipative many-body quantum systems, particularly the truncated Wigner representation, which works well for these systems due to the dissipation justifying the truncation of higher order quantum fluctuations. The particular physical system that I study with these methods is the optical parametric oscillator regime of polaritons in semiconductor microcavities, where multiple momentum modes become macroscopically occupied via parametric scattering of polaritons from the mode that is coherently pumped. My current research involves looking at the spacial correlations in this system to find evidence of the KPZ phase.

Conor Mc Keever

Research Interests: I am interested in a range of topics including quantum simulation, strongly correlated systems, open quantum systems out of equilibrium and quantum information. My current research focuses on developing tensor network state based methods to simulate many body quantum systems in driven-dissipative environments. In particular, I am interested in polariton lattices. In these systems, planar semiconductor microcavities are engineered such that the microcavity exciton-polaritons are strongly confined into 1D or 2D lattice geometries. As well as being a versatile platform for quantum simulation these systems offer an insight into topological states and non-equilibrium physics.
