Coupled Cluster Amplitude Extrapolation in Geometry Optimization
Jonas Beck, Michele Nottoli, Tommaso Nottoli +3
In this work, we present an amplitude extrapolation ansatz for geometry optimization that uses calculations from previous steps to construct an initial guess for the quasi-Newton s…
On the Regularity and Interpolation of Coupled Cluster Amplitudes in Canonical Orbital Basis
Jonas Beck, Benjamin Stamm
Arguably the most widely used approaches for obtaining highly accurate molecular ground-state energies are coupled cluster methods. Despite introducing two layers of approximation,…
Kekulé order from diffuse nesting near higher-order Van Hove points
Jonas Beck, Jonathan Bodky, Matteo Dürrnagel +4
Translation symmetry-breaking order is assumed to be suppressed by the lack of Fermi surface nesting near certain higher-order Van Hove singularities (HOVHS). We show the anisotrop…
Phase diagram of the - Heisenberg Model on the Maple-Leaf Lattice: Neural networks and density matrix renormalization group
Jonas Beck, Jonathan Bodky, Johannes Motruk +3
We microscopically analyze the nearest neighbor Heisenberg model on the maple-leaf lattice through neural quantum states (NQS) and infinite density matrix renormalization group (iD…
