Emergent Phases in an Extended Bose-Hubbard Model with Three-body On-site Interaction
Henry Otobrise, Kunle Adegoke
We study the Extended Bose-Hubbard Model with a three-body onsite interaction. Using an exact diagonalization method and a variational Matrix Product States algorithm, \emph{Alps m…

On approximating the free harmonic oscillator by a particle in a box
Kunle Adegoke, Adenike Olatinwo, Henry Otobrise +2
The main purpose of this paper is to demonstrate and illustrate, once again, the potency of the variational technique as an approximation procedure for the quantization of quantum…

Exact diagonalization of the dimensional confined quantum harmonic oscillator
Kunle Adegoke, Adenike Olatinwo, Henry Otobrise +2
In the existing literature various numerical techniques have been developed to quantize the confined harmonic oscillator in higher dimensions. In obtaining the energy eigenvalues,…
