摘要：

We numerically investigate the existence and stability of self-bound states forming in a one-dimensional binary bosonic condensate confined in non-parity-time ( $$\mathcal{PT}\mathcal{}$$ )-symmetric complex potentials under the influence of the Lee–Huang–Yang (LHY) correction. The linear spectrum of the non- $$\mathcal{PT}\mathcal{}$$ -symmetric complex potentials may undergo phase transition where the eigenspectrum changes from partially complex to all real through the adjustment of the phase transition parameter. Below ...
