Fermionic wave functions from neural-network constrained hidden states
We introduce a systematically improvable family of variational wave functions for the simulation of strongly correlated fermionic systems. This family consists of Slater determinants in an augmented Hilbert space involving “hidden” additional fermionic deg ...
2022Spinor GW /Bethe-Salpeter calculations in BerkeleyGW: Implementation, symmetries, benchmarking, and performance
Computing the GW quasiparticle band structure and Bethe-Salpeter equation (BSE) absorption spectra for materials with spin-orbit coupling have commonly been done by treating GW corrections and spin-orbit coupling (SOC) as separate perturbations to density- ...
AMER PHYSICAL SOC2022HP - 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 ...
ELSEVIER2022Ab Initio Electron-Phonon Interactions in Correlated Electron Systems
Nicola Marzari, Iurii Timrov, Matteo Cococcioni, Andrea Floris
Electron-phonon (e-ph) interactions are pervasive in condensed matter, governing phenomena such as transport, superconductivity, charge-density waves, polarons, and metal-insulator transitions. First-principles approaches enable accurate calculations of e- ...
AMER PHYSICAL SOC2021Visualizing the multifractal wave functions of a disordered two-dimensional electron gas
The wave functions of a disordered two-dimensional electron gas at the quantum-critical Anderson transition are predicted to exhibit multifractal scaling in their real space amplitude. We experimentally investigate the appearance of these characteristics i ...
AMER PHYSICAL SOC2021Mahan excitons in room-temperature methylammonium lead bromide perovskites
Majed Chergui, László Forró, Endre Horvath, Ana Akrap, Edoardo Baldini, Márton Kollár, Tania Palmieri
In a seminal paper, Mahan predicted that excitonic bound states can still exist in a semiconductor at electron-hole densities above the insulator-to-metal Mott transition. However, no clear evidence for this exotic quasiparticle, dubbed Mahan exciton, exis ...
NATURE PUBLISHING GROUP2020Quantum interference effects of out-of-plane confinement on two-dimensional electron systems in oxides
Emmanouil Frantzeskakis, Ji Dai
It was recently discovered that a conductive, metallic state is formed on the surface of some insulating oxides. First observed on SrTiO3 (001), it was then found in other compounds as diverse as anatase TiO2, KTaO3, BaTiO3, ZnO, and also on different surf ...
