We study the N-component (2+1)-dimensional Gross-Neveu model bounded between two parallel planes separated by a distance L at finite temperature (T). We obtain a closed expression for the large-N effective coupling constant ...

We propose the Woods–Saxon (WS) potential to simulate spatial confinement. The great advantage of our methodology is that it enables the study of a wide range of systems and confinement regimes by varying two parameters ...

We show that self-localized ground states can be created in the spin-balanced gas of fermions with repulsion between the spin components, whose strength grows from the center to periphery, in combination with the ...

We study the N-component (2+1)-dimensional Gross–Neveu model bounded between two parallel planes separated by a distance L at finite temperature T. From the four-point function, we obtain a closed expression for the large-N ...

Abstract: The potential curve for a confined He 2 dimer is computed using the variational method. The approach proposed here uses a trial function for the ground state composed of the Slater determinant with the orbitals ...
