    Analysis

    This paper explores squeezed states in composite bosons, specifically those formed by fermion pairs (cobosons). It addresses the challenges of squeezing in these systems due to Pauli blocking and non-canonical commutation relations. The work is relevant to understanding systems like electron-hole pairs and provides a framework to probe compositeness through quadrature fluctuations. The paper's significance lies in extending the concept of squeezing to a non-standard bosonic system and potentially offering new ways to characterize composite particles.

    The paper defines squeezed cobosons as eigenstates of a Bogoliubov transformed coboson operator and derives explicit expressions for the associated quadrature variances.
