Stellar model of compact star with dark matter equation of state
In this work we model compact stars with an equation of state of dark matter with admixed matter. Physical features of an exact solution of the Einstein system are explored by incorporating the effects of line...

Deep sub-barrier breakup dynamics in the \(^8{\mathrm{B}}+{}^{208}{\mathrm{Pb}}\) reaction
Breakup reactions at deep sub-barrier incident energies are the less investigated in the breakup of loosely-bound systems. Motivated by a recent study by Pakou et al (Phys. Rev. C 102:031601(R), 2020), we further...

Crystallization, Fermionization, and Cavity-Induced Phase Transitions of Bose-Einstein Condensates
Bose-Einstein condensates (BECs) are one of the cornerstones in the exploration of the quantum many-body physics of interacting indistinguishable particles. Here, we study them using the MultiConfigurational T...

Mesoscopic Bose-Einstein Condensate in Anharmonic Trap: Concept of Transition Exponent
We utilize a two-body correlated basis function and van der Waals interaction to describe interacting bosons in the anharmonic trap. We analyze the behaviour of specific heat capacity near the transition tempe...

Open AccessSorting Fermionization from Crystallization in Many-Boson Wavefunctions
Fermionization is what happens to the state of strongly interacting repulsive bosons interacting with contact interactions in one spatial dimension. Crystallization is what happens for sufficiently strongly in...

Neutron tunneling in nanostructured systems: isotopical effect
This contribution reports, to the best of our knowledge, for the first time on the neutron tunneling phenomenon in nickel isotopes based nanostructured. More accurately, 58Ni-62Ni-58Ni thin films Fabry-Perot reso...

Use of Two-Body Correlated Basis Functions with van der Waals Interaction to Study the Shape-Independent Approximation for a Large Number of Trapped Interacting Bosons
We study the ground-state and the low-lying excitations of a trapped Bose gas in an isotropic harmonic potential for very small ( $$\si...

A Few-Body Approach to Bose–Einstein Condensation
A simple method to calculate ground state energies for a typical condensates containing up to A ~ 107 atoms is presented. The method, based on the expansion of the wave function in terms of the Faddeev components...

Alpha-Particles within Nuclei
We present a formalism describing the bound state of a large number of bosons and apply it to study nuclei consisting of A α particles. The method has its roots in a few-body approach and is based on the expansio...

An Integro-Differential Equation for Bose–Einstein Condensates
We present an integro-differential equation describing systems with large number of bosons. The new equation includes the two-body correlations exactly into account and the kernel has a simple analytic form. T...

Three-Body Bound State Calculations Without Explicit Partial Wave Decomposition
The problem of calculating three-body bound state properties has been tackled by several authors for a considerable time. In the usual approach the partial wave decomposition of the solution is sought, resulti...
