QMCPACK: Advances in the development, efficiency, and application of auxiliary field and real-space variational and diffusion Quantum Monte Carlo
P. R. C. Kent, Abdulgani Annaberdiyev, Anouar Benali +21
We review recent advances in the capabilities of the open source ab initio Quantum Monte Carlo (QMC) package QMCPACK and the workflow tool Nexus used for greater efficiency and rep…
A Tunable Two-impurity Kondo system in an atomic point contact
Jakob Bork, Yong-hui Zhang, Lars Diekhöner +5
Two magnetic atoms, one attached to the tip of a Scanning Tunneling Microscope (STM) and one adsorbed on a metal surface, each constituting a Kondo system, have been proposed as on…
Mean-field quantum phase transition in graphene and in general gapless systems
Ádám Bácsi, Attila Virosztek, László Borda +1
We study the quantum critical properties of antiferromagnetism in graphene at T=0 within mean-field (MF) theory. The resulting exponents differ from the conventional MF exponents,…
Underscreened Kondo effect in quantum dots coupled to ferromagnetic leads
Ireneusz Weymann, Laszlo Borda
We analyze the equilibrium transport properties of underscreened Kondo effect in the case of a two-level quantum dot coupled to ferromagnetic leads. Using the numerical renormaliza…
Non-equilibrium current and relaxation dynamics of a charge-fluctuating quantum dot
C. Karrasch, S. Andergassen, M. Pletyukhov +4
We study the steady-state current in a minimal model for a quantum dot dominated by charge fluctuations and analytically describe the time evolution into this state. The current is…
Comment on "Twofold Advance in the Theoretical Understanding of Far-From-Equilibrium Properties of Interacting Nanostructures"
L. Borda, A. Zawadowski
Boulat, Saleur and Schmitteckert (BSS) reported results on the full characteristics of the interacting resonant level model (IRLM) exhibiting region with unexpected negative…
