HP - A code for the calculation of Hubbard parameters using density-functional perturbation theory
Nicola Marzari, Iurii Timrov, Matteo Cococcioni
We introduce HP, an implementation of density-functional perturbation theory, designed to compute Hubbard parameters (on-site U and inter-site V ) in the framework of DFT+U and DFT+U+V. The code does not require the use of computationally expensive superce ...
ELSEVIER2022Multiple Surface Site Three-Dimensional Structure Determination of a Supported Molecular Catalyst
Moreno Lelli, Pierrick Berruyer, David Benjamin Roger Antoine Gajan, Zhuoran Wang
The structural characterization of supported molecular catalysts is challenging due to the low density of active sites and the presence of several organic/organometallic surface groups resulting from the often complex surface chemistry associated with supp ...
AMER CHEMICAL SOC2022State selective cooling of SU(N) Fermi gases
We investigate a species selective cooling process of a trapped SU(N) Fermi gas using entropy redistribution during adiabatic loading of an optical lattice. Using high-temperature expansion of the Hubbard model, we show that when a subset N-A < N of the si ...
AMER PHYSICAL SOC2021Atomic scale investigations of fracture in metal alloys
The demand for metal alloys with superior structural performance in industrial applications continues to increase, as does the need for more-energy efficient materials and methods. Many materials that are otherwise attractive for structural applications ar ...
EPFL2021Highlights of the Science and Life of Peter Varga (1946-2018)
Peter Varga has passed on October 27, 2018. His pioneering discoveries of chemical resolution at the atomic scale on surface alloys, atomic resolution of ultrathin alkali halides, nucleation of bcc iron in ultrathin films, and the microscopic structure of ...
SURFACE SCI SOC JAPAN2020Multiple dehydrogenation reactions of negative ions in low pressure silane plasma chemistry
Christoph Hollenstein, Alan Howling, Antoine Descoeudres
Micro-particle formation in low pressure silane (SiH4) plasmas has been of technical interest and concern for at least 40 years. Negative ion plasma chemistry is a candidate for the initial nucleation, which has been extensively studied both experimentally ...
