At very high doping levels the van Hove singularity in the π* band of graphene becomes
occupied and exotic ground states possibly emerge, driven by many-body interactions …

Exotic ordered ground states driven by electronic correlations are expected to be induced in
monolayer graphene when doped to the Van Hove singularity. Such doping levels are …

Progress in performing angle-resolved photoemission spectroscopy (ARPES) with high
spatial resolution on the order of 1 lm or less (nanoARPES) has opened the possibility to …

Employing the density functional theory incorporating on-site and inter-site Coulomb
interactions (DFT+ U+ V), we have investigated the role of the nonlocal interactions on the …

A flat energy dispersion of electrons at the Fermi level of a material leads to instabilities in
the electronic system and can drive phase transitions. Here we show that the flat band in …

Superlattices from twisted graphene mono-and bilayer systems give rise to on-demand
many-body states such as Mott insulators and unconventional superconductors. These …

Integrating the carrier tunability of a functional two-dimensional material electronic device
with a direct probe of energy-and momentum-resolved electronic excitations is essential to …

Using time-and angle-resolved photoemission spectroscopy, we study the response of
metallic single-layer TaS 2 in the 1H structural modification to the generation of excited …

We apply the linear logarithmic relaxation (LLR) method, which generalizes the Wang-
Landau algorithm to quantum systems with continuous degrees of freedom, to the fermionic …

We investigate a layer of cobalt tetrapyridyl porphyrins (CoTPyPs) self-assembled on an
almost freestanding graphene (GR) sheet supported by Ir (111) with complementary …
