This paper reports the results of the adoption of a probabilistically defined communication
structure in a special algorithm coined as EPSO-Evolutionary Particle Swarm Optimization …

Despite concerted efforts, the problem of dilute local moments embedded in a correlated
conduction electron host such as Nd $ _ {1-x} $ Ce $ _x $ CuO $ _2 $ persists due to lack of …

We studied 2D surface state in the periodic Anderson model of a bulk topological Kondo
insulator (TKI) system, involving strongly correlated f orbital electrons screened by d orbital …

We investigate the ground-state properties of the periodic Anderson model on the square
lattice across various band fillings. Employing the infinite projected entangled-pair states …

The periodic Anderson model (PAM) is a fundamental model describing heavy fermion
systems' behavior. In this paper, we investigate the PAM in the presence of electron–phonon …

The interplay between the Kondo effect and magnetic ordering driven by the Ruderman-
Kittel-Kasuya-Yosida interaction is studied within the two-dimensional Hubbard-Kondo …

We study the ground-state properties of an extended periodic Anderson model to
understand the role of Hund's coupling between localized and itinerant electrons using the …

We investigate the behavior of the periodic Anderson model in the presence of d–f Coulomb
interaction (U df) using mean-field theory, variational calculation, and exact diagonalization …

Using a canonical transformation, it is possible to faithfully represent the Kondo lattice model
in terms of Majorana fermions. Studying this representation, we discovered an exact …

We have investigated the effects of the Coulomb interaction between conduction electrons
on the excitation gap of the Kondo insulator. As a theoretical model of the Kondo insulator …
