Survey of the Hierarchical Equations of Motion in Tensor-Train format for non-Markovian quantum dynamics
Etienne Mangaud, Amine Jaouadi, Alex Chin +1
This work is a pedagogical survey about the hierarchical equations of motion and their implementation with the tensor-train format. These equations are a great standard in non-pert…
Unveiling non-Markovian spacetime signalling in open quantum systems with long-range tensor network dynamics
Thibaut Lacroix, Angus Dunnett, Dominic Gribben +2
Nanoscale devices - either biological or artificial - operate in a regime where the usual assumptions of a structureless, Markovian, bath do not hold. Being able to predict and stu…
Simulating quantum vibronic dynamics at finite temperatures with many body wave functions at 0K
Angus J. Dunnett, Alex W. Chin
For complex molecules, nuclear degrees of freedom can act as an environment for the electronic `system' variables, allowing the theory and concepts of open quantum systems to be ap…
Dynamically Evolving Bond-Dimensions within the one-site Time-Dependent-Variational-Principle method for Matrix Product States: Towards efficient simulation of non-equilibrium open quantum dynamics
Angus J. Dunnett, Alex W. Chin
Understanding the emergent system-bath correlations in non-Markovian and non-perturbative open systems is a theoretical challenge that has benefited greatly from the application of…
The role of the multiple excitation manifold in a driven quantum simulator of an antenna complex
A. W. Chin, B. Le Dé, E. Mangaud +2
Biomolecular light-harvesting antennas operate as nanoscale devices in a regime where the coherent interactions of individual light, matter and vibrational quanta are non-perturbat…
Intermediate scattering function and quantum recoil in non-Markovian quantum diffusion
Peter S. M. Townsend, Alex W. Chin
Exact expressions are derived for the intermediate scattering function (ISF) of a quantum particle diffusing in a harmonic potential and linearly coupled to a harmonic bath. The re…
