On the effective reconstruction of expectation values from ab initio quantum embedding
Max Nusspickel, Basil Ibrahim, George H. Booth
Quantum embedding is an appealing route to fragment a large interacting quantum system into several smaller auxiliary `cluster' problems to exploit the locality of the correlated p…
Systematic improvability in quantum embedding for real materials
Max Nusspickel, George H. Booth
Quantum embedding methods have become a powerful tool to overcome deficiencies of traditional quantum modelling in materials science. However, while these are systematically improv…
Fully Algebraic and Self-consistent Effective Dynamics in a Static Quantum Embedding
P. V. Sriluckshmy, Max Nusspickel, Edoardo Fertitta +1
Quantum embedding approaches involve the self-consistent optimization of a local fragment of a strongly correlated system, entangled with the wider environment. The `energy-weighte…
Efficient Compression Of The Environment Of An Open Quantum System
Max Nusspickel, George H. Booth
In order to simulate open quantum systems, many approaches (such as Hamiltonian-based solvers in dynamical mean-field theory) aim for a reproduction of a desired environment spectr…
Frequency-dependent and algebraic bath states for a Dynamical Mean-Field Theory with compact support
Max Nusspickel, George H. Booth
We demonstrate an algebraic construction of frequency-dependent bath orbitals which can be used in a robust and rigorously self-consistent DMFT-like embedding method, here called $…
