Chain representations of open quantum systems and their numerical simulation with time-adapative density matrix renormalisation group methods
Alex W. Chin, Susana F. Huelga, Martin B. Plenio
This chapter gives a self-contained review of the how standard open quantum system Hamiltonians can be mapped analytically onto representations in which the environments appear as…
Mappings of open quantum systems onto chain representations and Markovian embeddings
M. P. Woods, R. Groux, A. W. Chin +2
We derive a sequence of measures whose corresponding Jacobi matrices have special properties and a general mapping of an open quantum system onto 1D semi infinite chains with only…
Quantum Metrology in Non-Markovian Environments
Alex W. Chin, Susana F. Huelga, Martin B. Plenio
We analyze precision bounds for a local phase estimation in the presence of general, non-Markovian phase noise. We demonstrate that the metrological equivalence of product and maxi…
A variational description of the quantum phase transition in the sub-Ohmic spin-boson model
A. W. Chin, J. Prior, S. F. Huelga +1
The sub-ohmic spin-boson model is known to possess a novel quantum phase transition at zero temperature between a localised and delocalised phase. We present here an analytical the…
