New Approaches for ab initio Calculations of Molecules with Strong Electron Correlation
Stefan Knecht, Erik Donovan Hedegård, Sebastian Keller +5
Reliable quantum chemical methods for the description of molecules with dense-lying frontier orbitals are needed in the context of many chemical compounds and reactions. Here, we r…
An Efficient Matrix Product Operator Representation of the Quantum-Chemical Hamiltonian
Sebastian Keller, Michele Dolfi, Matthias Troyer +1
We describe how to efficiently construct the quantum chemical Hamiltonian operator in matrix product form. We present its implementation as a density matrix renormalization group (…
Pair Correlations in Doped Hubbard Ladders
Michele Dolfi, Bela Bauer, Sebastian Keller +1
Hubbard ladders are an important stepping stone to the physics of the two-dimensional Hubbard model. While many of their properties are accessible to numerical and analytical techn…
