Entanglement generation from degeneracy breaking of superradiant Liouvillian steady states by local operations
Adam Burgess, Erik M. Gauger
Superradiance is a collective optical effect where emitters cooperatively radiate with a maximal intensity scaling proportional to the square of the number of emitters. Despite the…
Dynamics and spectra of open quantum systems coupled to anharmonic environments
Kian Damezin, Brendon W. Lovett, Erik M. Gauger +1
In open quantum systems, the environment is typically modelled as a collection of harmonic oscillators, whereas realistic environments often exhibit unique non-Markovian effects du…
Tensor network methods for non-perturbative dynamics of open quantum systems
Thibaut Lacroix, Adam Burgess, Nicola Lorenzoni +11
The description of open quantum system dynamics beyond the perturbative treatment (usually associated with Markovian master equations) is a computationally challenging task due to…
Scalable framework for quantum transport across large physical networks
Adam Burgess, Nicholas Werren, Erik M. Gauger
Accurately modelling many-body quantum transport systems poses a challenge both conceptually and computationally due to the growth of the Hilbert space and the multi-scale nature o…
Numerically exact open quantum system work statistics with process tensors
Mike Shubrook, Moritz Cygorek, Erik Gauger +2
Accurately quantifying the thermodynamic work costs of quantum operations is essential for the continued development and optimisation of emerging quantum technologies. This present…
Fermionic versus Spin Baths in non-Interacting Transport Models
Muhammad Zia, Moritz Cygorek, Erik M. Gauger +1
We investigate how fermionic anticommutation shapes transport in a noninteracting resonant-level model where a single central site is coupled to an environment. To this end, we com…
Time-nonlocal versus time-local long-time extrapolation of non-Markovian quantum dynamics
Moritz Cygorek, Erik M. Gauger
The high numerical demands for simulating non-Markovian open quantum systems motivate a line of research where short-time dynamical maps are extrapolated to predict long-time behav…
Optical signatures of coherence in molecular dimers
Priyankar Banerjee, Adam Burgess, Julian Wiercinski +2
We calculate experimentally measurable signatures of quantum correlations in a coupled molecular dimer that strongly interacts with its vibrational environment. We investigate inte…
Enhancing energy transport utilising permanent molecular dipoles
Adam Burgess, Erik Gauger
We study exciton quantum transfer along a molecular chain whilst accounting for the effects of permanent dipoles that are induced by charge displacements in the molecular orbitals.…
