This review addresses the method of explicit calculations of interatomic exchange
interactions of magnetic materials. This involves exchange mechanisms normally referred to …

Atomic layers deposited on semiconductor substrates introduce a platform for the realization
of the extended electronic Hubbard model, where the consideration of electronic repulsion …

We report on structural and electronic properties of superconducting nanohybrids made of
Pb grown in the ultrahigh vacuum on the atomically clean surface of single crystals of …

In this work we computed the phase diagram as a function of temperature and doping for a
system of lead adatoms allocated periodically on a silicon (111) surface. This Si (111): Pb …

Adsorption of one-third monolayer of Sn on an atomically clean Si (111) substrate produces
a two-dimensional triangular adatom lattice with one unpaired electron per site. This dilute …

We clarify the ground-state phase diagram of the half-filled square-lattice Hubbard model
with Rashba spin-orbit coupling (SOC) characterized by the spin-split energy bands due to …

Chiral superconductors are one of the predominant quantum electronic states of matter
where topology, symmetry, and Fermiology intertwine. This is pushed to a new limit by …

Superconductivity was recently observed in boron-doped (3× 3) Sn/Si (111). The material
can be described by an extended Hubbard model on a triangular lattice. Here, we use the …

We employ the weak-coupling renormalization group approach to study unconventional
superconducting phases emerging in the extended, repulsive Hubbard model on …

We address here general issues and show how to properly extract the local charge order in
two-dimensional systems from scanning tunneling microscopy/spectroscopy (STM/STS) …
