Calum Brown

My research focuses on the theory of open quantum systems, specifically the stochastic dynamics of systems subjected to repeated measurements. The evolution of a single trajectory of the system can reveal phenomena which are hidden in the standard ensemble-averaged description given by conventional master equations. I aim to understand how measurements and environmental interactions affect these trajectories of quantum systems and how this can be exploited for real-time feedback and adaptive control.

Joe Crossley

I'm primarily interested in strongly correlated many-body physics. During my PhD, I focussed on systems of interacting spins on a lattice. I studied the low-temperature thermodynamics of the spin-liquid candidate Ca10Cr7O28 and I explored the utility of the "Path Integral over Tensor Networks" tool applied to spin chains. At Nottingham, I will be working on novel approximations to correlated many-body ground states and on the application of various numerical methods to many-body quantum thermodynamics.

Joint with J.P. Garrahan

I am broadly interested in models with constraints. These include classical stochastic dynamics and large deviations, but also (classical and quantum) spin models. For both of these classes, I am interested in answering questions regarding the character of their phases, their phase transitions, and their dualities. Interests include topological phenomena, in- and out-of-equilibrium dynamics, tensor networks, dynamical facilitation and glasses and constrained satisfaction problems.

Jared Jeyaretnam

Joint with J.P. Garrahan, I. Lesanovsky, and B. Bertini

I am interested in non-equilibrium quantum many-body physics - in particular, ergodicity breaking (where matter taken out of equilibrium fails to thermalise), such as when strong quenched disorder is applied to an interacting system to localise it. I have also recently been studying fragmentation in lattice gauge theories and tensor network methods. At Nottingham, I will be taking these themes and combining them with a quantum circuit perspective.

My general research interests are in many-body physics and non-equilibrium systems. I am currently focused on the realisation of Majorana fermions in heterostructures that give rise to topological superconductivity. Primarily using analytical techniques, I explore how the Majorana fermions arise in vortices and the properties they have, especially those that will allow for their experimental verification, such as their non-Abelian statistics.

Anna Dalmasso

The main focus of my research is many-body physics, particularly topological systems in (2+1) dimensions. Using both analytical and numerical methods, I investigate the dynamics of anyonic excitations, with the first aim of developing a compact anyon-to-qubit mapping. I am also interested in these systems in the context of topological quantum computing and quantum error correction.

Caitlin Lewis

Jointly supervised with Jonathan Hirst and Katherine Inzani

I completed my undergraduate MSci degree in Chemistry and Molecular Physics at the University of Nottingham. My masters project, conducted within the Hirst group, focused on electronic structure calculations for protein Circular Dichroism. Now, I'm pursuing my PhD with the same group, exploring how quantum computing can enhance quantum chemistry research.
