OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors
Gerald E. Fux, Piper Fowler-Wright, Joel Beckles +11
Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. De…
Wavefront Curvature in Optical Atomic Beam Clocks
A. Strathearn, R. F. Offer, A. P. Hilton +5
Atomic clocks provide a reproducible basis for our understanding of time and frequency. Recent demonstrations of compact optical clocks, employing thermal atomic beams, have achiev…
Numerical evaluation and robustness of the quantum mean force Gibbs state
Yiu-Fung Chiu, Aidan Strathearn, Jonathan Keeling
We introduce a numerical method to determine the Hamiltonian of Mean Force (HMF) Gibbs state for a quantum system strongly coupled to a reservoir. The method adapts the Time Evolvi…
Exact dynamics of non-additive environments in non-Markovian open quantum systems
Dominic Gribben, Dominic M. Rouse, Jake Iles-Smith +6
When a quantum system couples strongly to multiple baths then it is generally no longer possible to describe the resulting system dynamics by simply adding the individual effects o…
Using the Environment to Understand non-Markovian Open Quantum Systems
Dominic Gribben, Aidan Strathearn, Gerald E. Fux +2
Tracing out the environmental degrees of freedom is a necessary procedure when simulating open quantum systems. While being an essential step in deriving a tractable master equatio…
Quantum heat statistics with time-evolving matrix product operators
Maria Popovic, Mark T. Mitchison, Aidan Strathearn +3
We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix pro…
Exact Quantum Dynamics in Structured Environments
Dominic Gribben, Aidan Strathearn, Jake Iles-Smith +4
The dynamics of a wide range of technologically important quantum systems are dominated by their interaction with just a few environmental modes. Such highly structured environment…
Efficient non-Markovian quantum dynamics using time-evolving matrix product operators
Aidan Strathearn, Peter Kirton, Dainius Kilda +2
In order to model realistic quantum devices it is necessary to simulate quantum systems strongly coupled to their environment. To date, most understanding of open quantum systems i…
Efficient Real-Time Path Integrals for Non-Markovian Spin-Boson Models
Aidan Strathearn, Brendon W. Lovett, Peter Kirton
Strong coupling between a system and its environment leads to the emergence of non-Markovian dynamics, which cannot be described by a time-local master equation. One way to capture…
