A versatile unitary transformation framework for an optimal bath construction in density-matrix based quantum embedding approaches
Quentin Marécat, Matthieu Saubanère
The performance of embedding methods is directly tied to the quality of the bath orbitals construction. In this paper, we develop a versatile framework, enabling the investigation…
Unitary transformations within density matrix embedding approaches: A novel perspective on the self-consistent scheme for electronic structure calculation
Quentin Marécat, Benjamin Lasorne, Emmanuel Fromager +1
In this work, we introduce an original self-consistent scheme based on the one-body reduced density matrix () formalism. A significant feature of this methodology is the utiliza…
Recursive relations and quantum eigensolver algorithms within modified Schrieffer--Wolff transformations for the Hubbard dimer
Quentin Marécat, Bruno Senjean, Matthieu Saubanère
We derive recursive relations for the Schrieffer--Wolff (SW) transformation applied to the half-filled Hubbard dimer. While the standard SW transformation is set to block-diagonali…
