QAssemble: A Pure Python Package for Quantum Many-Body Theory
Seongjun Mo, Dongming Li, Mancheon Han +5
QAssemble is a pure-Python package for the quantum many-body problem. It implements various functional approaches, such as tight-binding, Hartree-Fock, and GW approximations within…
Two Channel Multi impurity Kondo model
A. M. Tsvelik, G. Kotliar
We show that the Ruderman-Kittel-Kasua-Yoisida interaction between overscreened spins in two channel Kondo impurity systems is a relevant perturbation when the number of impurities…
Connection between f-electron correlations and magnetic excitations in UTe2
Thomas Halloran, Peter Czajka, Gicela Saucedo Salas +8
The detailed anisotropy of the low-temperature, low-energy magnetic excitations of the candidate spin-triplet superconductor UTe is revealed using inelastic neutron scattering.…
Low-energy perspective on two-orbital Hund metals and the case of LaNiO2
Fabian B. Kugler, Chang-Jong Kang, Gabriel Kotliar
The Hund-metal route to strong correlations continues to attract large interest in the condensed-matter community. The question arose to what extent it applies to the infinite-laye…
Vacancy-induced tunable Kondo effect in twisted bilayer graphene
Yueqing Chang, Jinjing Yi, Ang-Kun Wu +5
In single sheets of graphene, vacancy-induced states have been shown to host an effective spin-1/2 hole that can be Kondo-screened at low temperatures. Here, we show how these vaca…
EDRIXS: An open source toolkit for simulating spectra of resonant inelastic x-ray scattering
Y. L. Wang, G. Fabbris, M. P. M. Dean +1
Resonant inelastic x-ray scattering (RIXS) has become a very powerful experimental technique to probe a broad range of intrinsic elementary excitations, for example, from low energ…
Self-energies in itinerant magnets: A focus on Fe and Ni
L. Sponza, P. Pisanti, A. Vishina +6
We present a detailed study of local and non-local correlations in the electronic structure of elemental transition metals carried out by means of the Quasiparticle Self-consistent…
The Mott transition in V_2 O_3 and Ni Se_x S_{2-x}: insights from dynamical mean field theory
G. Kotliar
We discuss some aspects of the pressure (or interaction) driven Mott transition, in three dimensional transition metal oxides by means of dynami cal mean field theory. We isolate t…
First-principles Calculations of the Electronic Structure and Spectra of Strongly Correlated Systems: Dynamical Mean-field Theory
V. I. Anisimov, A. I. Poteryaev, M. A. Korotin +2
A recently developed dynamical mean-field theory in the iterated perturbation theory approximation was used as a basis for construction of the "first principles" calculation scheme…
