Dynamic Compressed Sensing for Real-Time Tomographic Reconstruction
Jonathan Schwartz, Huihuo Zheng, Marcus Hanwell +2
Electron tomography has achieved higher resolution and quality at reduced doses with recent advances in compressed sensing. Compressed sensing (CS) theory exploits the inherent spa…
Dielectric dependent hybrid functionals for heterogeneous materials
Huihuo Zheng, Marco Govoni, Giulia Galli
We derive a dielectric-dependent hybrid functional which accurately describes the electronic properties of heterogeneous interfaces and surfaces, as well as those of three- and two…
From real materials to model Hamiltonians with density matrix downfolding
Huihuo Zheng, Hitesh J. Changlani, Kiel T. Williams +2
Due to advances in computer hardware and new algorithms, it is now possible to perform highly accurate many-body simulations of realistic materials with all their intrinsic complic…
The importance of sigma bonding electrons for the accurate description of electron correlation in graphene
Huihuo Zheng, Yu Gan, Peter Abbamonte +1
Electron correlation in graphene is unique because of the interplay of the Dirac cone dispersion of electrons with long range Coulomb interaction. The random phase approximatio…
Density-matrix based determination of low-energy model Hamiltonians from ab initio wavefunctions
Hitesh J. Changlani, Huihuo Zheng, Lucas K. Wagner
We propose a way of obtaining effective low energy Hubbard-like model Hamiltonians from ab initio Quantum Monte Carlo calculations for molecular and extended systems. The Hamiltoni…
Computation of the correlated metal-insulator transition in vanadium dioxide from first principles
Huihuo Zheng, Lucas K. Wagner
Vanadium dioxide(VO) is a paradigmatic example of a strongly correlated system that undergoes a metal-insulator transition at a structural phase transition. To date, this trans…
