Matrix-product-state-based band-Lanczos solver for quantum cluster approaches
Sebastian Paeckel, Thomas Köhler, Salvatore R. Manmana +1
We present matrix-product state (MPS) based band Lanczos method as solver for quantum cluster methods such as the variational cluster approximation. While a naïve implementation of…
Parametrization of the Coulomb interaction matrix with point-group symmetry
Coraline Letouzé, Guillaume Radtke, Benjamin Lenz +1
Coulomb integrals, i.e., matrix elements of bare or screened Coulomb interaction between one-electron orbitals, are fundamental objects in many approaches developed to tackle the c…
Paramagnon dispersion and damping in doped NaCaCuOCl
Blair W. Lebert, Benjamin Bacq-Labreuil, Mark P. M. Dean +13
Using Resonant Inelastic X-ray Scattering, we measure the paramagnon dispersion and damping of undoped, antiferromagnetic CaCuOCl as well as doped, superconducting Na$_…
Order from disorder phenomena in BaCoS
Benjamin Lenz, Michele Fabrizio, Michele Casula
At the layered insulator BaCoS transitions to a columnar antiferromagnet that signals non-negligible magnetic frustration despite the relatively high $…
Two-dimensional fluctuations and competing phases in the stripe-like antiferromagnet BaCoS
Haneen Abushammala, Benjamin Lenz, Benoit Baptiste +5
By means of a combined x-ray diffraction, magnetic susceptibility and specific heat study, we investigate the interplay between orthorhombic distortion and stripe-like antiferromag…
Oxygen vacancies at the origin of pinned moments in oxide interfaces: the example of tetragonal CuO/SrTiO
Benjamin Bacq-Labreuil, Benjamin Lenz, Silke Biermann
Obtaining an accurate theoretical description of the emergent phenomena in oxide heterostructures is a major challenge. Recently, intriguing paramagnetic spin and pinned orbital mo…
