Signatures of many-body localisation in a system without disorder and the relation to a glass transition
James M. Hickey, Sam Genway, Juan P. Garrahan
We study a quantum spin system with local bilinear interactions and without quenched disorder which seems to display characteristic signatures of a many-body localisation (MBL) tra…
Fluctuation Theorems and the Generalised Gibbs Ensemble in Integrable Systems
James M. Hickey, Sam Genway
We derive fluctuation relations for a many-body quantum system prepared in a Generalised Gibbs Ensemble subject to a general nonequilibrium protocol. By considering isolated integr…
Localisation in space and time in disordered-lattice open quantum dynamics
Sam Genway, Igor Lesanovsky, Juan P. Garrahan
We study a two-dimensional tight-binding lattice for excitons with on-site disorder, coupled to a thermal environment at infinite temperature. The disorder acts to localise an exci…
Dynamical phase transitions, time-integrated observables and geometry of states
James M. Hickey, Sam Genway, Juan P. Garrahan
We show that there exist dynamical phase transitions (DPTs), as defined in [Phys. Rev. Lett. 110 135704 (2013)], in the transverse-field Ising model (TFIM) away from the static qua…
Dynamical Phases in the Full Counting Statistics of the Resonant-Level Model
Sam Genway, James M. Hickey, Juan P. Garrahan +1
We present a thermodynamic formalism to study the full counting statistics (FCS) of charge transport through a quantum dot coupled to two leads in the resonant-level model. We show…
Time-integrated observables as order parameters for dynamical phase transitions in closed quantum systems
James M. Hickey, Sam Genway, Igor Lesanovsky +1
The dynamical behaviour of many-body systems is often richer than what can be anticipated from their static properties. Here we show that in closed quantum systems this becomes evi…
Thermodynamics of Quadrature Trajectories in Open Quantum Systems
James M. Hickey, Sam Genway, Igor Lesanovsky +1
We apply a large-deviation method to study the diffusive trajectories of the quadrature operators of light within a reservoir connected to dissipative quantum systems. We formulate…
