Constrained Random Phase Approximation: the spectral method
Merzuk Kaltak, Alexander Hampel, Martin Schlipf +3
We present a constrained Random Phase Approximation (cRPA) method, termed spectral cRPA (s-cRPA), and compare it to established cRPA approaches for Scandium and Copper by varying t…
Machine Learning Study of Surface Reconstructions of the CuO(111) Surface
Payal Wadhwa, Michael Schmid, Georg Kresse
The atomic structure of the most stable reconstructed surface of cuprous oxide (CuO)(111) surface has been a longstanding topic of debate. In this study, we develop on-the-fl…
Magnetism-Enhanced Strong Electron-Phonon Coupling in Infinite-Layer Nickelate
Ruiqi Zhang, Yanyong Wang, Manuel Engel +12
Intriguing analogies between the nickelates and the cuprates provide a promising avenue for unraveling the microscopic mechanisms underlying high- superconductivity. While ele…
Comparative analysis of methods for calculating Hubbard parameters using cRPA
Indukuru Ramesh Reddy, M. Kaltak, Bongjae Kim
In this study, we present a systematic comparison of various approaches within the constrained random-phase approximation (cRPA) for calculating the Coulomb interaction parameter $…
Self-Refinement of Auxiliary-Field Quantum Monte Carlo via Non-Orthogonal Configuration Interaction
Zoran Sukurma, Martin Schlipf, Georg Kresse
For optimal accuracy, auxiliary-field quantum Monte Carlo (AFQMC) requires trial states consisting of multiple Slater determinants. We develop an efficient algorithm to select the…
Accurate Electron-phonon Interactions from Advanced Density Functional Theory
Yanyong Wang, Manuel Engel, Christopher Lane +9
Electron-phonon coupling (EPC) is key for understanding many properties of materials such as superconductivity and electric resistivity. Although first principles density-functiona…
