Phase stability, charge ordering, and charge-liquid formation in the Falicov-Kimball model on triangular and kagome lattices
Ammar Nejati, Marvin Lenk
We present a systematic investigation of the stability of the phase diagram of the spinless Falicov-Kimball model on two-dimensional non-bipartite lattices, the triangular and kago…
Oscillation and suppression of Kondo temperature by RKKY coupling in two-site Kondo systems
Ammar Nejati, Johann Kroha
We apply our recently developed, selfconsistent renormalization group (RG) method to STM spectra of a two-impurity Kondo system consisting of two cobalt atoms connected by a one-di…
Kondo Destruction in RKKY-Coupled Kondo Lattice and Multi-Impurity Systems
Ammar Nejati, Katinka Ballmann, Johann Kroha
In a Kondo lattice, the spin exchange coupling between a local spin and the conduction electrons acquires nonlocal contributions due to conduction electron scattering from surround…
A Two-Dimensional Approach to Evaluate the Scientific Production of Countries (Case Study: The Basic Sciences)
Ammar Nejati, Seyyed Mehdi Hosseini Jenab
The quantity and quality of scientific output of the topmost 50 countries in the four basic sciences (agricultural and biological sciences, chemistry, mathematics, and physics and…
Relative Positions of Countries in the World of Science
Seyyed Mehdi Hosseini Jenab, Ammar Nejati
A novel picture of the relative positions of countries in the world of science is offered through application of a two-dimensional mapping method which is based on quantity and qua…
Higher Order and boundary Scaling Fields in the Abelian Sandpile Model
S. Moghimi-Araghi, A. Nejati
The Abelian Sandpile Model (ASM) is a paradigm of self-organized criticality (SOC) which is related to conformal field theory. The conformal fields corresponding to some hei…
