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…
A Markovian approach to -photon correlations beyond the quantum regression theorem
Mateusz Salamon, Oliver Dudgeon, Ahsan Nazir +1
Multi-photon correlations from quantum emitters coupled to vibrational environments lie beyond the reach of standard tools such as the quantum regression theorem (QRT). Here, we in…
Arbitrary gauge quantisation of light-matter theories with time-dependent constraints
Adam Stokes, Ahsan Nazir
We provide a general framework for the quantisation of light-matter theories with time-dependent holonomic constraints. Unless time dependence is present from the outset at the Lag…
Cauchy-Schwarz bound on the accuracy of truncated models in non-relativistic quantum electrodynamics
Daniel Eyles, Adam Stokes, Ahsan Nazir
We show that the Cauchy-Schwarz inequality provides a simple yet general bound that limits the accuracy of light-matter theories which retain only finite numbers of material energy…
Non-Markovian Quantum Heat Statistics with the Reaction Coordinate Mapping
Mike Shubrook, Jake Iles-Smith, Ahsan Nazir
The definition of heat in quantum mechanics is ambiguous. Complications arise in particular when the coupling between a quantum system and a thermal environment is non-negligible,…
Capturing non-Markovian polaron dressing with the master equation formalism
Jake Iles-Smith, Owen Diba, Ahsan Nazir
Understanding the dynamics of open quantum systems in strong coupling and non-Markovian regimes remains a formidable theoretical challenge. One popular and well-established method…
